What Are Cookies

Analytics Cookies (Opt-in)
We use Google Analytics 4 to measure aggregate platform usage (pageviews, session counts, approximate geography). Analytics cookies are not set until you click “Accept analytics”on the banner shown on your first visit. If you decline, or haven’t answered yet, no analytics cookies are written and no data is sent.
We use Google’s Consent Mode v2, with IP anonymisation enabled. We do not use advertising cookies and no data is shared with third-party advertisers.
Managing Your Analytics Consent
To change your choice, clear the fedimpute.consent entry in your browser’s local storage (DevTools → Application → Local Storage) and reload the page — the banner will re-appear.
Local Storage
In addition to cookies, we use browser local storage to store your authentication token (JWT) for API requests. This token is cleared when you log out.
Managing Cookies
You can clear cookies through your browser settings. Note that clearing authentication cookies will log you out of the platform.
