Cookies and analytics
The site sets no advertising cookie and embeds no third-party tracker. This page describes the little that remains.
Cookies set
One only, and only if you change language: tb_lang, which remembers your choice so it is not asked again on every visit. Duration: one year. It contains no personal identifier.
Local storage
The seven-day challenge saves your progress in your browser’s local storage (localStorage). That data never leaves your device and is not transmitted to us. The "reset" button on the challenge page erases it.
Analytics
It works without cookies and without a persistent identifier: each page view is counted in isolation, with the page, the language, the device type, the referrer and any campaign parameters. The IP address is truncated before any recording. No profile is built, and no visit is linked to another.
Opting out
Your browser’s "Do Not Track" and GPC signals are respected: if either is enabled, nothing is recorded. No consent banner is shown because no processing requires one.
