1. What a cookie is here
A cookie is a small value your browser stores for this site and sends back on each request. We also use local storage for a few interface preferences. Both are covered by this policy — the technology matters less than what is kept and why.
2. Strictly necessary
The session cookie identifies your signed-in session. It is set when you log in, it is marked HttpOnly and Secure so scripts cannot read it, and it is deleted when you log out or when the session expires. Without it the platform cannot know who you are, so it cannot be switched off while you are signed in.
3. Preferences
Your language choice and your light or dark theme are stored so the site opens the way you left it. These are set by your own actions in the interface and are not shared with anyone.
4. Security
We record request metadata — address, browser, timestamp — for rate limiting, fraud detection and the session list you can review in your account. That is server-side logging rather than a cookie, and it is described here so the picture is complete.
5. What we do not use
No advertising cookies, no cross-site tracking pixels, no third-party analytics that profile you across the web. If that ever changes, this page changes first and you will be asked before any non-essential cookie is set.
6. Managing cookies
You can clear or block cookies in your browser settings. Blocking the session cookie will sign you out and prevent you from signing back in. Clearing preferences resets the language and theme to their defaults, and nothing else is lost.
