Rheenu uses a small amount of browser storage — mostly to keep you signed in and to keep working when your connection is patchy. Here is exactly what is stored and why.
Rheenu keeps you signed in using tokens stored by Firebase Authentication in your browser. Without these you would be signed out on every page load, so they cannot be turned off while you use an account.
We also use your browser's local storage to hold a copy of published content and any edits waiting to sync, so the site still works if your connection drops.
We measure how the core loop performs — quiz completions, check-ins, questions posted — so we can tell what genuinely helps people. These measurements are aggregated and not used to build advertising profiles.
If we add a third-party analytics tool, we will list it here and ask for consent first where the law requires it.
You can clear cookies and local storage at any time in your browser settings. Doing so signs you out and removes any locally cached content, but nothing you have published is lost.
Blocking essential storage entirely will prevent sign-in from working.
