2. What we process

Immoprobe is a calculator and a place to keep rental investment properties. You connect your own AI assistant (Claude or ChatGPT, say) yourself; its provider is your contractual partner, and we run no language model of our own. The calculator without an account needs no data from you; an account exists only with an e-mail address.

Land values, the other geodata and the map come from our own data on our own servers; no map provider receives your IP address. The only cookie is session (HttpOnly, Secure, SameSite=Strict); it is required for the service and needs no consent (§ 25(2) no. 2 TDDDG). There are no tracking, advertising or analytics cookies. Database backups are overwritten within 30 days of a deletion.
