Artificial intelligence
and data.

On this site, artificial intelligence is used in exactly one place: the home page, where what you write is sent to a language model that writes the answer shown. No other page calls a model. The rest of the site is text written by hand.

The model is gpt-5.4-mini, provided by OpenAI Ireland Ltd, declared as a processor in our privacy policy.

What you write passes through this site, goes to the model, and nothing of it is left here. Here is what that sentence covers, point by point.

• The request is sent with the option store: false. We ask the provider neither to keep the response, nor to cache the request.
• The text you write is written to none of our logs: not the service's, and not the web server's, where it never passes since it travels in the body of the request. What our traces carry are counters: the number of tokens of an answer, and the rank of the day.
• Your IP address is not kept. It serves to count your requests for the hour, and it is reduced for that to a salted fingerprint that lives only in the memory of the process. The salt is drawn at random at each start of the service: two days do not overlap, the fingerprint cannot be traced back to an address, and everything disappears on restart.

They are set in the code of the site, they are independent of one another, and none of them replaces the others.

• Five requests per hour and per visitor.
• Five hundred answers per day for the page as a whole.
• Five hundred characters at most in what you write.
• Three hundred and fifty words, and nine hundred tokens, at most in what comes back.
• Twenty-five seconds, after which the answer stops where it stands.

On their side, their own policy applies, and they are the ones who publish it: abuse monitoring logs are retained for up to thirty days, and data sent to their API is not used to train their models. Read the OpenAI policy.

What follows is the principle. The facts of a project are written in its contract, and it is the contract that binds.

• Only what is strictly necessary is sent to the model.
• The client's data stays with the client, and it trains no model.
• A person decides what binds the company. A model proposes, it does not sign.
• Nothing medical and nothing legal is settled by a model.
• Hosting is chosen according to what the law requires of the project, and it is written into the contract.

This site is hosted by Hetzner Online GmbH, in Germany, within the European Union. It is ordinary hosting: it carries no sector certification, and nothing on this site calls for one.
