INFORMATION WE COLLECT AND USE

“Personal information” is data that identifies, relates to, describes, can be used to contact, or could reasonably be linked directly or indirectly to you. For purposes of this Policy, there is no meaningful distinction between the terms “Personal information” and “Personal data”

  • Other information you may provide (including other information you provide about yourself or others through our Services or to which you provide us with access via third-party platforms)

You may choose not to provide some of the personal information described above. Please note, however, that many of our Services require some personal information to operate, including sensitive personal information, so if you choose not to provide the personal information necessary to operate and provide you with a particular Service or feature of that Service, you may not be able to use that Service or feature.

Sensitive Personal Information. Some of the information identified above, such as your passport number, redress travel number, and citizenship information, may be considered "sensitive personal information" under certain laws. Please be aware that this information may be required for certain bookings and we may not be able to complete such bookings without this information. In addition, our Services may include text boxes that are designed for you to describe certain details about your travel preferences or special requests that you want us or our travel partners to know, which may also be more sensitive in nature. Please be aware that information you freely submit in these boxes may reveal to us or to the travel partners or third parties with whom we share information (as detailed in the How We Share Your Information section below) certain information that may be considered sensitive personal information under applicable law (for example, information about dietary restrictions or disability accommodations). Lastly, certain features of our Services may prompt your device or browser to request access to your precise geolocation information, which may be considered sensitive personal information. We do not process precise geolocation absent you granting permission through your device or browser. Where you have voluntarily consented to our processing of your sensitive personal information, you may revoke such consent at any time by contacting us at the details set out in the How to Contact Us section below.

Personal Information Generated By Us. As you use our Services, we generate certain personal information about you, including through automatic data collection and by inferences based on the information we collect about you and your activity. We may automatically collect information about your interactions with the Services or communications you receive (such as email) using certain technologies, such as cookies, web beacons and other technologies (see our Cookies and Interest-Based Advertising Policy for more details). We generate the following categories of personal information about you:

  • Device information. When you visit or use our Services, we automatically collect certain information about your device (e.g., your mobile device, computer, or tablet), including information about your hardware and software, device configuration, and nearby networks. Such data may include data about your device operating systems, browsers, and other software installed on your device; such as IP address or other device identifier; country of origin, region and language settings; and information about domain servers and wireless or network access points near your device.
  • Usage and performance information. We also automatically collect personal information about your usage of the Services, including information about your searches, statistics about the travel itineraries you share with us, how you interact with the features of our Services and the links you click, your preferences, access times, referring URL, and performance of our Services.
  • Location information. If you use our Services, we automatically collect approximate location information about you (such as your city) or, with your consent, precise geographic location data from your mobile device when the app is running and when it is not running, depending on the choices you make when you are asked to consent to our collection of location information. The technologies we use to determine your location may include IP address mapping, cell tower position, Wi-Fi position and GPS signals. We may use and store this information to provide and improve features of our Services, for example, to tailor our Services on a needs-based manner to better facilitate your requests (such as helping you find the hotel closest to you) and to provide you with more relevant content in the cities you visit (such as sending you marketing communications relating to goods or services in your current city, including local accommodations and travel options). Cheapflights does not have control over your device settings, but we do recommend enabling location services on your device so you can take advantage of the location-based features and functionality offered. Please see the Your Rights and Choices section below for more information about how to adjust your preferences, including those related to location information.
  • Inferences about you. We combine the information we collect, generate, or otherwise obtain to draw inferences about your preferences and interests in order to provide and personalize our Services and tailor the advertising we and our partners display or offer to you.
  • Emails you synchronize with your Trips account. If you sign up to synchronize your email inbox to your Trips account, you authorize us to access the emails in the email accounts you have connected to your Trips account in order to create travel itineraries. This involves automatically scanning your inbox at regular intervals to identify emails that are booking confirmations, which are then parsed automatically or manually for relevant travel details and imported into our Trips service (along with a copy of the email, which is saved to your Trips account). See the Trips Services section below for more information.

Personal Information We Obtain from Third Parties. We may also receive certain categories of personal information from third parties, such as third-party websites, applications, social media networks, and services (each, a “third-party platform”), our group companies, travel partners, and other third parties, including individuals who have shared their travel itineraries with you through our Trips service. If you are an existing Cheapflights user, we will combine this information with information we collect through our Services and use and share it for the purposes described below. The categories of personal information we may obtain from third parties includes:

  • Your name
  • Email address or other contact information
  • Social media data, if you connect to our Services using a social media third-party platform or interact with Cheapflights by liking or commenting on our social media pages or content, we may receive information from that social media third-party platform about those interactions and from your social media profile (e.g., name, age, gender, photograph, and other personal information related to that account)
  • Browsing, purchase, usage and advertising details, including information about restaurant or travel accommodations and bookings you make through our group companies and travel partners (for example, if you book a flight through one of our group companies, we or our travel partners may receive the general location of your destination and use that information to provide recommendations for hotels or other accommodations or complementary services); how you use third-party websites, applications, and services; information relating to your interactions with our advertising and marketing materials; and demographic information about users of our Services.

  • Providing Trips services, including automatically creating a “Trips” account for you if you make a booking using our Services. This account collects your travel information to create and maintain your travel itineraries, which you can then share with others. If you sign up for the synchronization of your emails to our Trips service, we access the emails in the email accounts you have connected to your Trips account, to regularly review these emails in order to identify those that are booking confirmations that we can import into our Trips service, to parse these emails and to add the information we have collected (including a copy of the email to your Trips account) (see below for more detail on Trips Services)
  • Authenticate your account credentials and identify you, as necessary to log you in to the Services and ensure the security of your account
  • Show your reservations and bookings made through the websites, applications, and services of our group companies, such as Booking.com or OpenTable, on your account page
  • Communicate with you about your account or use of our Services, products, and/or functionality (e.g., soliciting reviews and feedback, sending alerts and notifications you have subscribed to, providing updates regarding itineraries processed by our Trips service, sending you booking confirmations, sending you information servicing and administrative emails or other notices required by law); respond to, or follow up on, your comments and questions; and otherwise provide customer service (see below for more detail on Electronic Communications)
  • Send you marketing communications, including communicating with you about services or products offered by KAYAK, our group companies, or our business partners and other marketing communications that we believe you would be interested in, as permitted by law (see below for more detail on Electronic Communications and Your Choices and Rights)
  • Operate and improve our Services and develop new products and services, including using analytics to better understand how you use our Services for purposes of product, website, application and service development and to enhance the user experience
  • Process and deliver contest entries and rewards
  • Process your payment information
  • Provide services and information to travel partners, such as providing user feedback and usage details
  • Tailor your experience with our Services, such as by making inferences or combining different pieces of information we have collected about you to offer better search results or otherwise tailor our Services to you according to your preferences or restrictions. For example, if you frequently book rooms at four-star hotels and rent cars when you travel, we may prioritize four-star hotels in your search results or bring you a combined package offer for hotel and car, or prioritize accommodations you have previously booked
  • Provide you more relevant advertising on and off our Services, including to show you personalized offers and advertising on and off our Services. For example, if you tend to book rooms at four-star hotels and often travel to Tokyo, we may display advertising for a four-star Tokyo hotel to you on our Services or work with our travel partners and advertising partners to display advertisements for four-star Tokyo hotels to you on other websites you visit.
  • Protect against, investigate, and deter fraudulent, unauthorized, or illegal activity
  • Comply with our policies, procedures and legal obligations, including complying with law enforcement or government authority requests, addressing litigation-related issues, and exercising rights or obligations conferred by law
  • As otherwise consented to by you and as required or permitted by applicable law. If you give your consent to any further use of personal information, you can withdraw that consent at any time by contacting us using the details set out below.

You have choices about your personal information, and in some circumstances, you may have the right to opt out or object to our uses of your personal information for these Purposes. For more information, or to exercise these or other rights (where available), see the Your Choices and Rights section below.

Trip Services. If you register for an account, send a booking confirmation to our Trips service or make a booking through our Services, you will have access to our Trips service, where we will collect your travel information to create and maintain your travel itineraries. If you directly send us booking confirmation emails, you authorize us to parse these emails automatically or manually and to add the information you provide to your Trips account, along with other information that we have collected (including saving a copy of the original email to your Trips account). If you sign up for the synchronization of your emails to our Trips service, you authorize us to access the emails in the email accounts you have connected to Trips, to regularly review these emails in order to identify those that are booking confirmations that we can import into our Trips service, to parse these emails automatically or manually and to add the information we have collected to your Trips account (including saving a copy of the original email to your Trips account). To the extent permissible by our email synchronization partners, we use the information in your Trips account to show you more relevant search results (e.g., accommodations you previously booked) or to provide you statistics about your travels, and we may use such information for marketing communications as described above. If you use or have itineraries as part of our Trips Service, you can send or grant access to your itinerary to anyone you choose. Your itinerary may contain enough details (e.g., booking reference codes) to allow the recipient to cancel or modify your booking, perform a check-in, etc. You should only share your itinerary with people you trust. Please also refer to our Getting Started with Trips page and the detailed Trips FAQ for answers to frequently asked questions, and visit your Account page to update your account settings and preferences. If you choose to display your itinerary on publicly-viewable web pages (Facebook, for instance), that information may be collected and used by others.

Electronic Communications. Consistent with the above Purposes and as permitted by applicable law, we may communicate with you via electronic messages, including email, text message, or mobile push notification to:

  • Send you information relating to our products and Services. This may include booking confirmations and updates, receipts, technical notices, updates, security alerts, and support and administrative messages.
  • Send you marketing communications. In other situations, subject to the Your Choices and Rights section below and applicable law, we may communicate with you about contests, offers, promotions, rewards, upcoming events, and other news about products and Services offered by us, our group companies, our travel partners, and other business partners.

With your consent, where required, we may contact you at the mobile phone number that you provide to us by way of direct dial calls, autodialed and prerecorded message calls, and text messages in connection with the above Purposes.

Our Role as Data Controller. For purposes of European Union law and similar data protection regimes, we generally act as a data controller, meaning we determine the purposes and means of processing your personal information. Our travel partners to whom we may connect you to make reservations are also generally independent data controllers. To learn more about how our travel partners may use your personal information, we encourage you to review their privacy notice.

Processing Bases and Consequences. When we process your personal information, we rely on the following legal bases:

  • Performance of the contract we have with you (for example, if you use our Services to book a flight, we will process your information in order to allow the relevant airline partner to complete and administer that booking).
  • Compliance with legal obligations to which we are subject (such as when we are obliged to comply with lawful requests from competent authorities such as law enforcement).
  • To serve our legitimate interests (such as tailoring your experience with our Services, carrying out online advertising, and for fraud detection), provided that such processing does not outweigh your rights and freedoms. The processing must also be pursuant to other applicable legal bases for data processing, especially provisions set out under local law.

When we use personal information to meet our legitimate interests, we take steps to ensure that your rights to your personal information are not infringed. You can contact us using the details set out in the How to Contact Us section below for more information about the steps we take to ensure these rights are not infringed. You also have the right to object to such processing as described in the Your Choices and Rights section below.

  • Consent. To the extent that a legal ground described above would not apply to processing of your personal information by us, we will seek your consent for such specific purpose in accordance with applicable law (such as sending direct marketing messages by electronic means, like email, without an exception from the requirement to obtain consent).

Aggregate Information. We aggregate personal information collected directly from you, information generated about you by us, and information obtained from third parties (with your consent, where required) with personal information collected about other users in order to produce general statistics that cannot be linked to you or any other specific user. Information that has been aggregated and de-identified is no longer considered “Personal information” and may be subsequently used for any purpose.

Anonymized Information. We may process information that cannot be linked to you or any other specific user using any means available to us, either because it was collected anonymously or has been subsequently anonymized. Information that is anonymous or has been anonymized is no longer considered “Personal information” and may be subsequently used for any purpose.

HOW WE SHARE YOUR INFORMATION

  • With our travel partners. We share your information with our travel partners to provide the Services (such as connecting users with airlines or online travel agents to book a flight or other travel service, and sharing personal details, contact information, passport information, preferences, requests, accommodations, and other information with the airline or online travel agent) and for our travel partners' own purposes, which may include marketing or advertising purposes (see below for more detail on Sharing with Travel Partners).

Sharing with Travel Partners. Our travel partners include online travel agencies, hotels, airlines, car rental companies, and travel insurance providers. When you make a request for a booking or reservation from one of our partners through our Services, we share your information with that travel partner to facilitate the booking or reservation and provide the services you requested. Depending on the request, this may include your name, contact information, passport information, frequent flyer details, itinerary details as described above, your preferences, any special requests or accommodations, information or comments that you choose to submit (if any), and other information as required by the particular travel partner. Your information is provided to the travel partner, just as it would be if you contacted the travel partner directly. If you provide a mobile phone number in connection with your request, travel partners may send you text messages regarding your request. Some travel partners also require you to provide credit or debit card account information to secure your reservation.

When you make a request, we also share with the travel partner additional information about you, such as information about your travel activity and history, and/or information that we collect from you and third parties. Travel partners use this information for their own purposes, which may include to improve their products or services and to provide you with targeted advertising and marketing communications, where permitted under law.

Sharing with Our Group Companies. We share your information with our affiliates and subsidiaries in the U.S. and worldwide, as well as with our parent corporation, Booking Holdings, Inc., and its other subsidiaries (collectively, as also defined earlier in this Privacy Policy, our “group companies”). We may share your information with our group companies for the following reasons:

  • Provide you with integrated services (including to administer and manage reservations, bookings, services, and payments across our affiliated platforms).
  • Provide personalized offers or send you marketing communications with your consent or as otherwise permitted by applicable law.
  • Enable “single sign-on”, i.e., allowing you to log into a shared account for multiple Booking Holdings Inc. brands using a single set of log-in credentials, which allows us to, for example, show your reservations and bookings made through the websites, applications, and services of our group companies on your account page, and allow our group companies to show information in your respective account(s) with them.
  • Provide customer support services.
  • Detect, prevent, and investigate fraud and misuse of our services, other illegal activities, and data breaches.
  • Analyze how users use our independent and affiliated platforms, including so that we may improve existing products and services and develop new features, products, and services that may be of interest to our users.
  • Ensure compliance with applicable law.

To learn more about your choices related to how we share your information with our group companies (including our subsidiaries, our parent company, and its other subsidiaries), please see the Your Choices and Rights section below.

Sharing with Our Business Partners. We share your information with other third-party business partners for their own marketing purposes. These third parties include online advertisers or ad tech companies, who may provide you with targeted advertising and marketing communications, where permitted under law. The information we share includes information collected through your use of our Services (e.g., information about your bookings and reservations for flights, hotels, car rentals, or other travel accommodations) and information we collect about you through the use of cookies and similar technologies (e.g., information about the websites you visit; information about your searches, including the cities or destinations you search for, the types of accommodations you search for, your travel preferences, price range, intended travel dates, and the number of travelers in your party).

For example, if you frequently search for flights from Seattle to Paris around certain holidays, we may share that information with a particular airline partner so it can better understand which of our customers are interested in flights from Seattle to Paris on certain dates. The airline partner may then, for example, use this information to offer you a promotion.

To learn more about your choices related to how we share your information with our business partners, please see the Your Choices and Rights section below.

Sharing with Social Networking Services. Our Services allow you to connect and share your actions, comments, content, and information publicly or with friends. Our Services may also allow you to connect with us on, share on, and use third-party platforms, including those on which Cheapflights has a presence. Please be mindful of your personal privacy needs and the privacy needs of others as you choose whom to connect with and what to share and make public. We cannot control the privacy or security of information you choose to make public or share with others. Cheapflights also does not control the privacy practices of third-party platforms. Please contact those sites and services directly to learn about their privacy practices.

Sharing to Process Payment Information. To use certain Services (such as to book a flight) and to make payments to certain of our travel partners, we require payment information (e.g., credit or debit card account information, other online payment method information, etc.). When you submit your payment information through our Services, we will share that information with travel partners, third-party payment processors, and other third-party service providers (including, but not limited to, vendors who provide fraud detection services to us and other third parties), to the extent necessary to meet our contractual obligations to you (e.g., to secure your reservation or make a payment to a travel partner where required), to meet our legitimate interests in preventing fraud and other misuses of our platforms or Services, or with your consent where this is required by law. In particular:

  • When you use a credit or debit card to secure a booking or reservation through our Services, we provide your credit or debit card account information (including card number and expiration date, and if required by the travel partner, CVV number) to the applicable travel partner to process the transaction.
  • When you provide your credit or debit card account information through our Services, you will have the option to save your information to your account for future use.

We do not authorize these third parties to use or disclose your information for purposes other than those for which it has been provided. We require these third parties to maintain and implement security measures to protect your information from unauthorized access or processing.

HOW WE STORE AND PROTECT YOUR INFORMATION

Cheapflights maintains commercially-reasonable technical, administrative, and physical security measures designed to protect your information from loss, misuse, unauthorized access, disclosure, alteration, and destruction.

You play an important role in keeping your information secure. You should not share your user name, password, or other security information for your Cheapflights account with anyone. If we receive instructions using your user name and password, we will assume you have authorized the instructions.

When your payment information is being transmitted to our Services or through our Services, it will be protected by cryptographic protocols. To be clear, Cheapflights only stores your payment information if you choose to save that information to your account. When you submit a booking or reservation, we transfer your payment information to the applicable travel partner to process the transaction. Our contracts with third parties that receive your payment information require them to keep it secure and confidential.

However, we cannot guarantee that transmissions of your payment information or your other information will always be secure or that unauthorized third parties will never be able to defeat the security measures taken by Cheapflights or our third-party service providers. Except to the extent that liability cannot be excluded or limited due to applicable law, we assume no liability or responsibility for disclosure of your information due to errors in transmission, unauthorized third-party access, or other causes beyond our control.

Retention. We may retain your personal information for as long as your account is active and for a period of up to five years thereafter to allow you to re-activate your account without loss of information. We may also retain your personal information as necessary to:

COOKIES AND INTEREST-BASED ADVERTISING POLICY

What are Cookies?

Cookies and similar tracking technologies, such as beacons, scripts, web beacons and tags (which together we refer to as “cookies”), are small bits of text, usually stored on a user's computer hard drive or within a browser. They enable a website to remember information about the user's visit to the website. On mobile websites and mobile applications, we use device IDs and / or Advertising IDs in a similar manner to which we use cookies.

We and certain third-party partners (as described below) use cookies on our websites, our mobile applications and within emails or other communications we send to you (we refer to these together as our “Sites”).

To the extent the cookies we use for these purposes lead to the processing of your personal information, details about how we use that personal information and your rights over that personal information are discussed in our Privacy Policy.

What types of Cookies are used on our Sites and what do we use them for?

We use “first-party cookies,” i.e., those that are used solely by us or by third parties who act only on our instructions or on our behalf. These types of cookies are used for our own analysis of our own Sites, or to provide functionality such as remembering your language preference.

Other cookies on our Sites are used both by us for the purposes described in this policy and by third parties for purposes where those third parties may wish to combine information from our Sites with information from other sites to improve their services. For example, these types of cookies may be used for interest-based advertising purposes.

The cookies used on our Sites, by either us or by third parties, can be “session” cookies, or “persistent” cookies. “Session” cookies are deleted automatically when you close your browser, and are used for things like ensuring you are kept logged in as you navigate around our Sites. “Persistent” cookies remain stored on your device or browser even after you close it. These cookies are used, for example, to recognize you when you come back to our Sites.

We divide the cookies we use into three categories:

Type of cookieDescription of how we use this type of cookieWhat choices do you have?
Required

To provide a secure log-in to our Sites.

To keep you logged in so that you do not have to log in repeatedly to access different pages of the Sites.

Required cookies are necessary for our Sites to operate. On some platforms, you can delete all cookies, but this may affect the basic functionality of the Sites.
Functional

To recognize you if you have visited previously, and remember your preferences from past visits, such as your language preference.

To track when you make purchases or bookings on websites operated by our group companies (e.g., travel bookings on Booking.com, restaurant reservations on OpenTable, or car rentals on Rentalcars.com), so that we can display your bookings with our group companies on your account page.

To improve our Sites and our offerings by helping us to understand how users use the Sites and to analyze trends which appear in that data. For example, we make changes to the user interface if we can see that certain pages are difficult for a large number of users to navigate. We also collect broad information about how our users use the Sites, for example, to understand which aspects of our Sites and our services are particularly popular, so that we can make improvements going forward.

To personalize your experience of our Sites, for example, by showing you offers on our homepage or in emails that are most relevant to you based on your previous visits to our Sites or those operated by our group companies or by ranking certain types of options (e.g., only non-stop flights) higher in your search results.

Where required by law, functional cookies will only be used on the Sites where you have given your consent to their use.

You can opt out of our use of Google Analytics by downloading the browser add-on

Advertising (e.g., Google DoubleClick, Google Ads, Oath, Bing Ads)

To recognize you if you have used our services on another device. We combine information received from multiple devices to determine if you are using a new device, so that we can continue to provide you with a personalized experience on our Sites.

To enable you to post to social media sites and other platforms, for example, to allow you to access a particular social media page to post a comment or a “like.”

To collect information for use in advertising on our own Sites and on third party sites which you may visit. Such information is based on your preferences and your usage of our Sites. We have included more information about our use of advertising cookies below.

We work with third parties that place cookies on our Sites to provide their services, including:

  1. Ad Targeting. We work with third-party advertising companies to serve ads while you are visiting our Sites and to permit these companies to place and access their own cookies on your computer in the course of serving advertisements on our Sites.

    These companies may use information obtained through their cookies (which does not include your name, address, e-mail address or telephone number) about your visits to our Sites and other websites, in combination with information about your purchases and interests from other online sites in order to provide advertisements about goods and services of interest to you.

    We also allow certain third parties (as described in our Privacy Policy to collect web log data from you (which may include IP address, where permitted, and information about your browser or operating system), when you visit our Sites, or to place or recognize a unique cookie on your browser to enable you to receive customized ads or content. The cookies may reflect de-identified usage data or other data linked to data you voluntarily have submitted to us, for example, your email address, that we may share with third parties solely in hashed, non-human readable form.

  2. Advertising Analytics/Measurement. We make use of analytics cookies as part of our online advertising campaigns to learn how users interact with our Sites after they have been shown an online advertisement, which may include advertisements on third-party websites. In particular, our Sites use Google Analytics 360 Suite, including Google Analytics Advertising, which are web analytics and analytics advertising services provided by Google, Inc., which use third party cookies. Where required, our Sites have activated the IP address anonymization functionality so that the IP address of the user is shortened by Google. Our Sites also use the following Google Analytics Advertising features: Google Remarketing, Google Segments, Google Ads Manager and Google Ads. These features use third party cookies to collect information about our website traffic by tracking users across websites and across time and generating reports for us to better understand our website users and to create audiences for our advertisements based on such understanding.
  3. Remarketing Pixel Tags. In addition, we may share website usage information about visitors to our Sites with third-party advertising companies for the purpose of managing and targeting advertisements and for market research analysis on our Sites and other sites. For these purposes, we and our third-party advertising companies may place pixel tags (also called clear gifs) on some of the pages you visit on our Sites. We will then use the information that is collected using these pixel tags to serve you relevant advertisements when you are visiting other sites on the Internet. These advertisements may be based on your interests, for example, on the basis of specific searches you conducted on our Sites during earlier browsing sessions.
  4. Other Cookies: Our partners, who provide certain features on our Sites or display advertising based on your browsing activity, also use Local Storage such as HTML5, to collect and store content information and preferences. Please note that different web browsers offer their own management tools for removing HTML5 local storage.

Mobile Devices, Anonymous Device Identifiers and Hashed IDs. We and/or third parties that we have engaged may collect and store a unique identifier matched to your mobile device, in order to deliver customized ads or content while you use applications or surf the internet, or to identify you in a unique manner across other devices or browsers. In order to customize these ads or content, we or a third party may collect de-identified usage data or other data about you which you have either voluntarily submitted to us, for example, your email address, or has been passively collected from you, such as your device identifier or IP address, where permitted. However, if we share your email address, we share it solely in hashed, non-human-readable form.
