How we use cookies & local storage

We keep our use of cookies minimal. We do not use advertising or cross-site tracking cookies. The storage we use falls into two buckets:

Strictly necessary

  • Supabase authentication cookies — keep you signed in. Essential for accounts.
  • geo_country — a short-lived cookie storing your approximate country code, used to decide regional feature eligibility (e.g. US-only offers).

Functional (on your device only)

  • Local storage keys for your theme, unit preferences, check-ins and profile when used without an account, and your privacy choices. These never leave your device unless you sign in to sync.

Third-party

  • Cloudflare Turnstile may set its own storage to perform bot checks during sign-up/sign-in.

Managing cookies

Because we only use strictly-necessary and functional storage, the app works without advertising cookies. You can clear local data anytime from Account → Privacy & Data, or via your browser settings. Contact privacy@mybmi.ai with any questions.
