Where your data is

Generative Cities runs in Switzerland: the website backend, the database and the AGC model are hosted by Infomaniak in Geneva. Your questions are not sent to services outside Switzerland. The website pages are delivered by Vercel; they do not store your questions or account data.

What we store

• Questions to AGC and its answers, with the time, the language, the building you had selected and your 👍/👎 feedback. Guests are identified only by a salted, one-way code derived from their network address; we do not store IP addresses.
• Your account, if you create one: email address, optional name, your user type, building unlocks and settings. Passwords are stored only as secure hashes. With Google sign-in we receive your email and name from Google, nothing else.
• A daily question counter per guest or account, to apply the question limits.

Why

To answer your questions, to apply the limits of your user type, and to improve AGC. Questions may be used, after removing personal details, to train future versions of AGC. You can opt out in your account (“Do not use my questions to train AGC”).

How long

Questions and answers are kept for at most 24 months; anonymised copies used for training may be kept longer. Account data is kept until you delete your account.

Your rights

You can see, correct and delete your data. Signed-in users can delete their account, including their stored questions, at any time in the account dialog. For anything else, use the Contact link at the top of this page.

The numbers

All energy, CO₂ and cost figures are modelled estimates for typical use, not measurements, and not financial, investment, tax or legal advice.
