DoEveryday stores your habits and check-ins in your own DoEveryday account (Supabase Postgres, encrypted at rest).

The extension communicates only with:
• supabase.co — to read and write your habits and check-ins
• accounts.google.com / appleid.apple.com — only when you choose to sign in with Google or Apple

The only data the extension transmits is your authentication session (to sign you in) and your own habit data (to your own account). We do not sell your data, we do not track you across the web, and the extension does not inject scripts into other websites — it runs only on its own pages (the new-tab override and toolbar popup) plus a message relay on doeveryday.app.
