What this covers

This notice explains the cookies and similar technologies (such as browser local storage) used on our website and app.

Essential storage

Authentication: when you sign in, we store session tokens in your browser’s local storage to keep you signed in. These are necessary for the service to work.

Security: Cloudflare Turnstile may set a token to verify that public form submissions are genuine.

Preferences: we store your cookie choice so we don’t ask again.

Analytics (only with consent)

We do not load analytics or any non-essential tracking unless you accept it via our cookie banner. If you accept, we may use privacy-respecting analytics to understand and improve how the site is used. You can withdraw consent at any time by clearing your browser storage.

Managing cookies

You can decline non-essential cookies in our banner, and you can clear or block cookies and local storage in your browser settings. Blocking essential storage may stop parts of the service from working.
