Privacy Policy

Last updated: April 2026

Toothhound is built to leak as little as possible. We don’t require an account, we don’t sell data, and your finds stay on your device by default.

What we store on your device

Logbook entries — finds, photos, notes, and conditions you record. Stored in your browser’s IndexedDB. Never transmitted to us.
Notification preferences — saved location subscriptions, kept inlocalStorage.
Cached map tiles & data — for offline use, held by the service worker.

NOAA CO-OPS — tide station IDs and date ranges for predictions. No personal data.
Open-Meteo — site coordinates and date ranges for weather. No personal data.
Google Gemini API — when you use the AI tooth identifier, the photo you upload is sent to Google’s vision model for classification, then discarded by us. Google’s data handling applies; review their terms.
Vercel Analytics & Speed Insights — aggregated, cookie-less page-view and Web Vitals telemetry. No IP storage, no fingerprinting. See Vercel’s policy.
CARTO basemaps + unpkg — map tile and Leaflet asset CDNs. They see your IP because your browser fetches the tiles directly.

None set by Toothhound itself.

Toothhound is suitable for all ages and does not knowingly collect personal data from anyone, children included.

You can export or delete your logbook at any time from the Logbook page. To wipe everything: clear site data in your browser settings.

If we materially change this policy, we’ll bump the “last updated” date and call it out on the home page.
