Cookie policy.

A session cookie for signing you in (essential), and a small preferences cookie remembering your theme, accent colour, density and unit system (essential to honour your choices).

Stripe sets cookies during checkout to prevent fraud. If cookieless analytics (Plausible/Umami) are enabled, they set none. We use no advertising or cross-site tracking cookies.

You can clear or block cookies in your browser at any time — signing in and theme memory will stop working, everything else keeps functioning.
