Terms of Use

Last updated: July 13, 2026

These Terms of Use (the “Terms”) are a legal agreement between you and Technology One, Inc., a Delaware corporation (“we”, “us”), governing your use of the TideWatch mobile application (the “App”), including the TideWatch Pro subscription. By downloading or using the App, you agree to these Terms. If you don’t agree, don’t use the App.

TideWatch is a planning tool, not a navigational aid. Tide and weather forecasts are predictions and can be wrong. Never rely on the App for navigation, or for any decision where an error could put people or property at risk.

1. License

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, for your own non-commercial use, in accordance with the usage rules of the app store you downloaded it from. You may not copy, modify, reverse-engineer, resell, or redistribute the App, or use it to build a competing product.

2. TideWatch Pro subscription

Some features are available only with TideWatch Pro, an auto-renewing subscription.

Price and term: $9.99 per year, following a 30-day free trial. Prices are in U.S. dollars and may vary by region; the exact price is shown in the App before you confirm.
Free trial: if you cancel before the trial ends, you are not charged. If you don’t cancel, the subscription begins automatically at the end of the trial.
Auto-renewal: the subscription renews automatically each year unless you cancel at least 24 hours before the end of the current period. Your store account is charged for renewal within 24 hours before the period ends.
Cancelling: manage or cancel at any time in your Apple or Google account settings — see Support for the steps. Cancelling stops future renewals; you keep Pro through the end of the period you have already paid for.
Billing: payment is charged to your Apple or Google account. We never see or handle your payment card details.
Price changes: we may change the price. Changes apply to future renewals only, and the store will notify you and, where required, ask for your consent before the new price takes effect.

Founding Members

Some early users have been granted complimentary access to Pro features as “Founding Members”. This access is provided free of charge and at our discretion; it is not a purchased subscription and confers no payment or refund rights.

Refunds

Purchases are processed by Apple and Google, and refunds are handled under their policies, not ours. Request a refund through Apple or the Google Play order history. Except where the law requires otherwise, subscription fees are non-refundable and we do not provide partial refunds for unused portions of a term.

3. Forecast data and its sources

Tide predictions are sourced from the NOAA Center for Operational Oceanographic Products and Services (CO-OPS). Weather and marine forecasts are sourced from Open-Meteo. We are not affiliated with, endorsed by, or sponsored by either.

This data is provided to you as-is. Tide predictions are astronomical estimates that do not account for weather, storm surge, or local conditions. Marine and weather forecasts are model output. Actual conditions will differ, sometimes substantially. Activity recommendations in the App are generated by a deterministic scoring model from that same forecast data — they are a convenience, not advice, and they are only as good as the forecast behind them.

4. Your responsibilities

You are solely responsible for decisions you make about entering the water, boating, fishing, walking on tidal flats, or any other activity. Always consult official sources — the U.S. Coast Guard, the National Weather Service, and local authorities — and use your own judgment.

5. Ownership

The App, its design, and its content (excluding third-party forecast data) are owned by Technology One, Inc. and are protected by intellectual property law. These Terms grant you a license to use the App — they do not transfer ownership of anything.

6. Disclaimer of warranties

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ANY FORECAST OR PREDICTION IT DISPLAYS WILL BE ACCURATE.

7. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TECHNOLOGY ONE, INC. WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF YOUR USE OF (OR INABILITY TO USE) THE APP — INCLUDING ANY INJURY, LOSS, OR DAMAGE RESULTING FROM RELIANCE ON TIDE, WEATHER, OR MARINE INFORMATION. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE APP WILL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE.

Some jurisdictions do not allow certain limitations, so parts of the two sections above may not apply to you.

8. Changes and termination

We may update the App or these Terms. If we make a material change to these Terms, we’ll update the “last updated” date above and, where appropriate, notify you in the App. Continuing to use the App after a change means you accept the revised Terms. We may suspend or terminate your access if you breach these Terms. You can end this agreement at any time by deleting the App.

9. Apple App Store

If you downloaded the App from the Apple App Store, you acknowledge that: these Terms are between you and Technology One, Inc. only, not Apple; Apple has no obligation to provide maintenance or support for the App; if the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price, and Apple has no other warranty obligation whatsoever; Apple is not responsible for addressing any claim by you or a third party relating to the App, including product liability, regulatory, or intellectual-property claims; and Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

10. Governing law

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Any dispute will be brought in the state or federal courts located in Delaware, and you consent to their jurisdiction. Nothing here deprives you of the protection of mandatory consumer-protection laws in your place of residence.
