Privacy policy

The short version

If you don't sign in, nothing about you leaves your device. Your tracker log and settings are stored in your browser's local storage on your own machine. We collect no analytics on launch, run no ad trackers, and set no marketing cookies.

If you sign in

Cloud sync uses Google sign-in. We receive and store your Google account email address (that's the entire profile we keep), a secure session identifier, and the drink entries you choose to sync. You can delete your synced data at any time with the Sign out + Clear controls, or by emailing us. Synced entries live in a Cloudflare D1 database in the region serving the API.

What we never do

• Sell or share your data with anyone.
• Send you email (we don't ask for it beyond your Google address, and we don't write to it).
• Track you across other sites.

AI agents

This site exposes public tools so AI assistants can look up caffeine facts. Those tools return public drink data only — the daily_total tool reads your log from your own browser and sends it nowhere.
