Cookie Notice
The cookies and browser storage Chronos uses. Only what the service needs; no tracking.
Effective 22 October 2026
In short
Chronos uses only strictly necessary cookies, to sign you in and keep sign-in safe, and stores dashboard preferences in your browser. There are no analytics, advertising or tracking cookies, and none from third parties for those purposes, so there is nothing to opt in to.
Cookies
| Cookie | Set by | Why | Lasts |
|---|---|---|---|
__session, __client_uat | our sign-in provider, on chronos.2090.tech | keep you signed in to the site and dashboard | the session; renewed while you use it |
__client | our sign-in provider, on its sign-in subdomain of 2090.tech | remember your sign-in across visits; protect sign-in from abuse | until you sign out, or up to the provider’s session lifetime |
Signing in may also involve a bot-protection check that sets its own necessary cookie. All of these are needed for the service to work, so they are set without asking.
Browser storage
The dashboard keeps your preferences in your browser’s local storage, never sent to us:
- theme, sidebar, table density, hidden columns and column widths, diagram layout;
- the world you last looked at in each project;
- the SQL editor’s open tabs and query text, and simulation drafts, so they’re there when you come back.
Clearing your browser’s site data removes them.
Your choices
You can block or delete cookies in your browser’s settings. If you block the necessary ones, you won’t be able to sign in. Signing out ends the sign-in cookies.
