KAYAK is part of the Booking Holdings Inc. corporate group, which includes Booking.com, OpenTable, Priceline, Agoda, and Rentalcars.com, (collectively, “our group companies”). In some cases, we receive personal information from our group companies, and we share personal information with our group companies.
For more information about the information we share with third parties and the recipients of such information, please refer to the How We Share Your Information section of this Policy.

“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/My Trips Services. If you register for an account, send a booking confirmation to our Trips/My Trips service or make a booking through our Services, you will have access to our Trips/My 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/My Trips account, along with other information that we have collected (including saving a copy of the original email to your Trips/My Trips account). If you sign up for the synchronization of your emails to our Trips/My Trips service, you authorize us to access the emails in the email accounts you have connected to Trips/My Trips, to regularly review these emails in order to identify those that are booking confirmations that we can import into our Trips/My Trips service, to parse these emails automatically or manually and to add the information we have collected to your Trips/My Trips account (including saving a copy of the original email to your Trips/My Trips account). To the extent permissible by our email synchronization partners, we use the information in your Trips/My 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/My 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/My Trips page and the detailed Trips/My 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.
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.
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:

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.

Cookies and Interest-Based Advertising.

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). KAYAK 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.

Legal Rights. Where applicable under local law, you may have the following rights regarding your personal information: the right to access personal information we hold, and in some situations, the right to have that personal information corrected or updated, erased, restricted, or delivered to you or a third party in a usable electronic format (the right to data portability).

Where we are using your personal information on the basis of your consent, and where applicable under local law, you have the right to withdraw that consent at any time. Where you have granted consent to receive direct marketing communications from us, and where applicable under local law, you may withdraw that consent at any time.
If you wish to exercise the legal rights you may have under applicable law, please submit your request by using our feedback form. So that we can better process your request, please provide the email you use to log into your KAYAK account.

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.

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.
