Cookie Policy

Effective November 7, 2026

What cookies are

Cookies are small text files a website stores in your browser. “Local storage” is a similar browser feature. This policy covers both.

Everything we store in your browser

All of these are first-party. No third party can read them.

Categories

  • Essential:required for sign-in, security and remembering your cookie choice. These don't need consent and can't be switched off, but you can block them in your browser (sign-in will then stop working).
  • Diagnostics (optional): if you turn it on, our error monitor (Sentry) keeps a short, privacy-masked replay of the moments before an error (text, inputs and images hidden) and sends it only if an error happens. Off by default. Error reports without replays are sent either way and contain no personal data or cookies.
  • Advertising:we don't use any.

Changing your choice

You can change or withdraw your choice at any time. Rejecting is as easy as accepting, and it doesn't limit any feature.

We store your choice for 12 months, then ask again. We also respect your browser's cookie controls.
