Privacy, plainly.

This site sets no analytics, no advertising and no tracking of any kind. One value is stored in your browser’s local storage: your day/night display preference. It never leaves your device.

Server logs record requests the way web servers do (IP address, path, time) and are used only to operate and protect the service.

If you use the “Ask” assistant, the question you type is sent to our server and processed with the help of Anthropic’s Claude API under a zero-data-retention configuration to generate an answer from our own public documentation. Questions are handled as content, not identity: don’t include personal data in them. If you leave your e-mail address for a follow-up, we use it to reply and for nothing else.
