Cookie policy
Last updated: 2026-08-31
We use strictly necessary cookies only. That is why you see no consent banner: for strictly necessary cookies the law does not require one, and we place no advertising or behavioural analytics cookies at all.
What is set and when
| Cookie | When it appears | Purpose | Lifetime |
|---|---|---|---|
| session | After signing in | Keeps you signed in and ties requests to your account. It is signed and marked HttpOnly, Secure and SameSite. | Session, expiring on inactivity |
| csrf | On the forms inside the application | Prevents a form on another site being submitted in your name | Session |
| cf_* | On the anti-bot check of the contact form and on Cloudflare protection | Tells a human from a robot and filters abusive traffic | Up to 30 minutes |
What we do not set
No advertising, retargeting or social network cookies. No behavioural analytics - no Google Analytics, no click maps, no session recordings.
Local storage in your browser
The application keeps your interface preferences in your browser: language, timezone, panel layout, chart drawings. These are not cookies and they go to no third party; they are removed when you clear site data in the browser.
How to control them
You can delete or block cookies in your browser settings. If you block the session cookie signing in stops working - it is the cookie that keeps the account open. The public site can be read without it.
