Tide Privacy Policy

Effective 2026-08-24.

The short version

Tide does not have a server. The app runs entirely on your device. We do not collect, log, or upload anything about you. There is no account.

Nothing leaves your device. The following data is read only on-device:

Location (when in use) — used to suggest nearby NOAA tide stations and to compute accurate sun, moon, and solunar times for your spot. Coordinates are never transmitted off the device.
Saved spots (station IDs, your nicknames) — stored locally in SwiftData on the device. They are not synced, backed up to us, or shared.
Notification preferences — stored locally and used to schedule local notifications.

The app makes no network requests at all. Tide predictions, sun, moon and solunar figures are computed on the device from data bundled in the app.

None. We don't ship any SDK that talks to a server.

The app is rated 4+ and does not collect data from any user.

Delete the app to remove every byte of local data. There is nothing stored anywhere else.
