What a booking keeps
A date, a length, a district or a hotel name, the way you asked to be replied to, and a reference number. Not your room number, which is said downstairs and never typed; not your full name unless you give it; not an IP address, not a copy of a document. Ask after the evening and the record is deleted.
At the hotel
The meeting is in the lobby or at the bar, and nothing is said at reception unless the hotel registers visitors; where it does, you know before the time is confirmed, and she gives her name as your guest. The model never has your number and you never have hers: the chat is with the agency, and it carries the brand name only if you have an account and asked for notifications.
An account, if you want one
A booking needs no account: a date and a way to reply are enough. If you open one, it holds your favourites, your bookings and your questions, signed in through Telegram, Google or email, and it is deleted in one step from settings. Reviews appear under a pseudonym and never mention a name, a hotel or a date. Discreet mode in the header blurs every photograph until you hover over it.
The formal version is in the Privacy Policy.
