Cookie notice
Last updated 7 October 2026
Cookies are small files a website stores in your browser. This site uses only the ones listed here. It uses no advertising, tracking or analytics cookies, and it stores nothing else in your browser (no local storage).
| Cookie | Purpose | Lasts | Needs your consent? |
|---|---|---|---|
sm_session | Keeps you logged in (only if you log in) | 7 days | No: strictly necessary |
sm_consent | Remembers your choice on this page | 180 days | No: strictly necessary |
sm_visitor | Lets you continue your public-page conversations on this device | 90 days | Yes. Set only if you press Accept |

If you reject
The public chat still works. Your conversation stays on the page while it is open, and is lost when you close or reload it. To limit abuse we count questions per visitor with a hashed form of your IP address, which is not a cookie (see the privacy notice).
Changing your mind
Use “Cookie settings” at the foot of any page to accept or reject again. Rejecting after accepting removes the visitor cookie at once. You can also delete cookies in your browser settings.
