Terms of Use
Last updated: July 2026
Independent tide predictions
Tidewell is an independent tide-prediction app. It is not affiliated with, authorised by, or endorsed by any hydrographic office, port authority, or government agency. Tide predictions are calculated using standard harmonic methods and are estimates only.
Not for navigation
Independent tide-prediction app. Tide predictions are estimates and must not be used for navigation. Do not rely on Tidewell for navigation, diving, or any safety-critical decision. Always consult official marine charts, tide tables, and your local authority for those purposes.
Purchases
A one-time in-app purchase (“Tidewell Pro”) unlocks unlimited favourite stations, widgets and tide alarms. Purchases are handled by Apple under the App Store terms and verified via RevenueCat; refunds are managed by Apple.
Acceptable use
The app and its content are for your personal use. You may not redistribute, resell, or scrape station or tide data from the app.
No warranty
The app is provided “as is”. While we work hard on prediction accuracy, we don’t warrant that any tide time is exact — actual water levels can differ due to weather, air pressure, and local conditions.
Changes
We may update these terms from time to time; the current version is always posted at gettidewell.app/terms.
