Terms of Use

Effective July 3, 2026

Ebb is an offline tide and solunar app for iOS made by Tundra Industries. By using it you agree to these terms — kept as short and human as we can make them.

The purchase

Ebb's core is free. The one-time purchase ("Ebb — Offline Forever") unlocks everything, permanently, on the Apple ID that bought it. It is not a subscription and never renews — there is nothing to cancel. Purchases and refunds are handled by Apple under their standard terms; restore it any time on a new device with Restore Purchases.

What Ebb is — and what it isn't

Ebb is a fishing-planning tool. It computes tide and solunar predictions from NOAA harmonic data so you can plan a trip. It is not a navigation or safety product and must not be relied on for any purpose where an error could put you or anyone else at risk.

Predictions are computed from NOAA harmonic data. Ebb is a fishing-planning tool — always follow official sources for navigation. Conditions, weather, and local factors change tides in ways no prediction can capture; official real-time sources are always the authority.

No warranty

Ebb is provided as-is. We work hard to keep its predictions dependable and validate them against NOAA's own published tables, but to the maximum extent allowed by law we disclaim warranties of any kind and are not liable for indirect or consequential damages. Our total liability is limited to what you paid for the app.

Changes

If these terms change, the current version will always be at this address. Continuing to use Ebb after a change means you accept it.
