In some cases, we receive personal information from our group companies, and we share personal information with our group companies.

“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.”
Personal Information We Collect Directly From You. As you visit or use our Services, we collect the following categories of personal information directly from you:
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, 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.
We do not proactively collect sensitive personal information, such as health-related information. However, our Services 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. 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). Sensitive personal information you voluntarily submit is processed on the basis of your consent, which you may revoke 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:
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 KAYAK 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:
We use your personal information for the following purposes (“Purposes”), to:
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.
Trips 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 authorise 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 synchronisation of your emails to our Trips service, you authorise 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 synchronisation 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:
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 data controllers. To learn more about how a travel partner may use your personal information, you should review its privacy notice.
Processing Bases and Consequences. When we process your personal information, we rely on the following legal bases:
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.
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.
We disclose the personal information we collect (or otherwise generate or obtain) as follows:
In some circumstances, you may have the right to opt out or object to our sharing of your information with certain third parties. For more information, or to exercise these or other rights, see the Your Choices and Rights section below.
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.
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.
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 KAYAK 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. KAYAK 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:
Sharing with Other Service Providers. We share information with third-party vendors, consultants, and other service providers who perform services or functions on our behalf (e.g., hosting or operating our Services, data collection, manually parsing booking confirmations, reporting, ad response measurement, site analytics, data analysis, delivering marketing messages and advertisements, processing credit card payments, and providing fraud detection services). 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.
KAYAK maintains commercially-reasonable technical, administrative, and physical security measures designed to protect your information from loss, misuse, unauthorized access, disclosure, alteration, and destruction.
When your payment information is being transmitted to our Services or through our Services, it will be protected by cryptographic protocols. To be clear, KAYAK 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 KAYAK 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. You play an important role in keeping your information secure. You should not share your user name, password, or other security information for your KAYAK account with anyone. If we receive instructions using your user name and password, we will assume you have authorized the instructions. If you have reason to believe that your interaction with us is no longer secure (e.g., if you feel that the security of any account you might have with us has been compromised), please contact us immediately as detailed in the How to Contact Us section below.
Retention. We may retain your personal information for as long as your account is active and for a period of time thereafter to allow you to re-activate your account without loss of information. We may also retain your personal information as necessary to:
When you use or visit the Services, we collect information about your usage and activity using cookies, web beacons, and other technologies. Third parties may also view, edit, or set their own cookies. We and our third-party service providers, affiliates, and other business partners may also place web beacons for these third parties. The use of these technologies by third parties is subject to their own privacy policies and is not covered by this Policy, except as required by law. See our Cookies Policy for more details.

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.

We work with third parties that place cookies on our Sites to provide their services, including:
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.
When you first visit our Sites, where required by law, you will have the option to give your consent to the advertising and functional cookies we use, or to refuse your consent to our use of those cookies by clicking on the [X] within that disclosure.
Browsers. Most browsers accept cookies by default. You may be able to change the settings to have your browser refuse certain cookies or notify you before accepting cookies. To do so, please follow the instructions provided by your browser which are usually located within the "Help", "Tools" or "Edit" facility. Some third parties also provide the ability to refuse their cookies directly by clicking on an opt-out link, and we have tried to indicate where this is possible in the table above.

Please keep in mind that, without cookies, you may not have access to certain features on our Sites, including access to your profile/account and certain personalized content. Removing all cookies from your computer could also affect your subsequent visits to certain websites, including our Sites, by requiring that, for example, you enter your login name when you return to that website. Please note that even if you exercise any of the choices described above, you will still see ads, but they will not be based upon the information collected through these tracking technologies, and therefore not necessarily relevant to your interests.
