The short version: Ebb collects nothing. There is no account, no server, no analytics, and no tracking of any kind. Everything the app knows about you stays on your phone.
Ebb has no backend. Your favorite stations, chosen units, and alert settings are stored on your device only, in storage the app shares with its widget. Nothing is uploaded, because there is nowhere to upload it to. The tide engine runs entirely on-device — the app makes no network requests except the purchase flow described below.
If you allow it, Ebb uses your location while you're using the app (when-in-use) for a single purpose: to sort the station list by distance so the nearest tide stations float to the top. That reading is used once, in the moment, on your device. It is never stored and never transmitted. Deny the permission and Ebb works fine — you'll just search or scroll for your station instead.
We do not use analytics SDKs, advertising identifiers, or any tracking technology. We cannot see which stations you check, when you fish, or anything else you do in the app.
The one-time unlock is processed by Apple and, on our side, by RevenueCat (our purchase infrastructure), which receives a random device identifier so the app can remember your purchase is valid and restore it later. It receives none of your data — not your location, not your stations, nothing you do in the app. See RevenueCat's privacy policy.
Delete the app and everything Ebb stored goes with it — favorites, settings, scheduled alerts, all of it. There is no copy anywhere else, because there was never a copy anywhere else.
Ebb is not directed at children under 13 and collects no data from anyone.
If this policy ever changes, the current version will always be at this address.
