What's Your Sign?
KAYAK does not collect any of your personally identifiable information (“PII”) when you do basic searches on the site. However, certain services we provide require you to authorize us to collect PII, including your name (and the traveler name, if different), email address, phone number, password, credit card information, passport number and billing address. Our software uses the PII to personalize and manage the KAYAK website for you. Here are some examples of services we can provide if you authorize us to use your PII:
With your credit card information and billing address, we can facilitate your reservations.
Your name, travel dates, destination, itinerary, supplier (airline, hotel etc.), passport number, email address, telephone number, credit card information and billing address may be necessary to process your booking on our site and/or to provide you valuable information about our services or those of our partners.
If you choose KAYAK personal trip management service (the “My Trips Service”), you authorize us to collect your travel information in order to create and maintain your travel itineraries.
So, remember, if you do decide to use any of these KAYAK services and give us PII about you, you are telling us that this PII is true, accurate and current. Also, you are telling us that you have the authorization to provide us with that PII.
In order to make our site more efficient, we may also collect certain information (such as destination or site usage behavior) based on your use of KAYAK. We may use this information to display advertising that you find interesting and suppress advertising that you might find boring or annoying. For example, we might show you travel offers from your home airport. Also, we may use this information to send you targeted email-marketing messages that you might find interesting.
To help us debug problems with our software, we may collect some technical information from your browser software (such as Mozilla Firefox or Internet Explorer), screen resolution and the website that referred you to us.
