Cookies and local storage

Last updated 3 November 2026.

No advertising cookies and no tracking cookies. That is why there is no cookie banner. We only use storage that is strictly needed to run the site and app.

What we use

Your browser's local storage / IndexedDB (enerchi.app): your profile, language, theme, journal and settings. It never leaves your device. Clear it in Me → Delete data or in your browser settings.
Sign-in session (Supabase): keeps you signed in after you log in. Removed when you sign out.
Checkout (Paddle): Paddle may set strictly necessary cookies or storage to run the payment window and prevent fraud.
Service worker cache: lets the app open offline.
Analytics: cookieless page and feature counts from Vercel. No identifiers are stored in your browser.

If we ever add anything that is not strictly necessary, we will ask for your consent first and update this page.
