Cookies
Citerra sets cookies for one purpose, which is keeping you signed in. It runs no analytics, no advertising and no cross-site tracking. This page names every cookie set, says what is not set, explains why there is no consent banner, and says how to control them.
§ 1
What Citerra sets
These carry your session. Blocking them signs you out and prevents you from signing back in, because they are what the session is. They are set by Clerk, the authentication provider, and Clerk stores no personally identifiable information in them by default.
Nothing is stored on your device until you sign in to the app. Reading citerra.de sets no cookie at all, signed in or not: the marketing site neither reads nor mints a session.
| Cookie | What it does | How long |
|---|---|---|
| __client | The client token. A signed token on clerk.citerra.de holding a client id and a rotating anti-fixation token, from which each host mints its own session. HttpOnly, and never readable by the page. | 7 days, the session lifetime Clerk applies |
| __session | The session token for one host. A short-lived signed token carrying your user id, refreshed from the client token as you browse. | Under a minute, then refreshed |
| __client_uat | Says whether a session probably exists, so a page can decide whether to attempt a handshake before it renders. Carries a timestamp and nothing else. | Until you sign out |
| __clerk_db_jwt | Development only. Keeps a session in step between localhost and the Clerk development domain. It is never set on citerra.de. | Development sessions only |
§ 2
What Citerra does not set
No analytics cookies, no advertising cookies, and no cross-site tracking. This website loads no tag manager and no third-party script.
Session replay is switched off on the editor, because a replay of the writing surface would record an unpublished paper keystroke by keystroke. Error reports carry a stack trace with personal data removed.
The application remembers interface choices such as the theme and the panel sizes in your browser's local storage. That never leaves your device and is not a cookie.
§ 3
Why there is no banner
The law requires consent for cookies that are not strictly necessary. Every cookie on this page is strictly necessary, so there is nothing to ask you about. A dialog whose only control is an always-on toggle would waste your click.
If Citerra ever adds an analytics or marketing cookie, this page gains a group for it and a preferences dialog appears. The decision is stored and can be revoked. That change would be announced before it takes effect.
