1. What we use and why
Strictly necessary technologies make the service work (signing you in, protecting against attacks, remembering your language, display preferences and consent choice). The law does not require consent for them, and they can't be switched off.
Optional technologies (browser error monitoring and product analytics) are used only after you accept them in the cookie banner or in Cookie settings, and you can withdraw consent at any time. We do not use advertising or cross-site tracking cookies.
2. How to control them
Use Cookie settings (in the footer and in Settings → Privacy) to accept, reject or change optional categories. Withdrawing consent stops the optional tools and removes their storage from your browser. You can also block or delete cookies in your browser settings, but blocking strictly necessary cookies will prevent you from signing in.
3. Changes
When we add a new optional category, we will ask for your consent again.
