This is an extract from an archived copy, fetched 19 August 2026. Booking.com didn't author this page for us. It's a snapshot we captured from https://www.booking.com/content/privacy.html. We hold the whole page and publish this part of it: the sentence a verdict rests on, with the text either side, so you can see it hasn't been lifted out of an exception.

The entry cited this capture from 19 August 2026 until 24 August 2026, when the document was re-read; it now cites the capture of 7 September 2026. This page stays so that anything that linked it still works.

The passage, in context

Paragraph 86 of 474

We may send you a warning or other notice if a trip provider reports misconduct by you.

To do this, we use personal data such as your first and last name, email address, and reservation details, including reservation IDs and chosen locations.

We sometimes invite our customers to participate in market research. Review the information that accompanies this kind of invitation to understand what personal data will be collected and how it's used.

We use personal data about travelers using our platform for analytical purposes, including for analyzing how you or travelers like you with similar interests use our platform, understanding customer sentiment and satisfaction, measuring our operating performance and improving trip services. We may process your user ID for the purpose of measuring the audience visiting our websites. We may use your personal data to develop and enhance our machine learning models and artificial intelligence systems. This is a necessary part of our ongoing commitment to make our services better and enhance our travelers' experience. For further details, see the section How we use artificial intelligence and make automated decisions .

In addition to the statistics we generate regularly about our business, we use data to perform experiments (such as A/B tests) to try out and troubleshoot platform features. The main goal here is to get insights into how our services perform, how they are used, and ultimately how to optimize and customize our website and mobile apps, in an effort to make them easier and more meaningful to use. In order to achieve this purpose, we may combine personal data we collect from you during different visits to our platform or visits on different devices or different websites of ours, even when you are not logged in.

To do this, we use personal data such as:

Reservations made by travelers over specific periods of time or for specific products

Checking the rest of it

The complete page is kept here and isn't republished. It's Booking.com's copyrighted document, and an extract is what a reader needs to check a quotation. The SHA-256 above is of that whole snapshot: fetch the page yourself, hash it, and you can tell whether ours has been altered without having to trust us.

If you work for Booking.com, or you are researching this and need the full capture, ask us for it and we will send it. If you believe a quote here is wrong or out of date, send us the paragraph. The correction gets published beside the clause.
