Privacy

This site uses no tracking and no advertising cookies.

It sets one technical cookie, lang, when you choose a language with the switch, so the next visit opens in that language. It holds only the language code and lasts a year.

The calculators and the question form run in your browser and send nothing unless you press a button that sends the result, by the channel you chose. The check-up with the assistant works differently, and the paragraph below says how.

The site is served by Cloudflare, which processes technical request data such as your IP address to deliver pages and protect the site.

The check-up with the assistant works differently. What you type is sent to Google, which writes the reply with its Gemini model. Ours is a paid plan, and for paid plans Google's terms say the text is not used to improve its products and is kept for 55 days, only to detect abuse and to meet legal obligations. At the end of each conversation we receive an email with the conversation and the result, which stays in our mailbox like any other message. If you choose to leave a name, a phone number or an email at the end, it arrives in that email, and we use it only to reply to you. Of the conversation we keep nothing else: no database, no copy. To keep the service within its limits we count each connection's conversations for two days, under a code that changes every day and does not contain your address.
