Terms of Service

Welcome to SnapshotWatt (“the App”), developed by CompoundWater. By downloading or using the App, you agree to these terms.

1. What the App does

The App estimates charging power from how fast the battery level rises and the phone’s battery capacity, and logs each charge. iOS only gives apps the battery level in 5% steps, so the watts shown on iPhone are estimates and may differ from the actual power. They are not readings from a professional measuring instrument. The Mac app reads battery data provided by macOS.

2. Using the App

• No account is needed and your data stays on your device. Back up anything you need; deleting the App deletes all its records.
• Charge safely according to the instructions of your charger, cable and phone manufacturers. The App does not control or change charging in any way.

3. In-app purchases

• SnapshotWatt Pro is a one-time purchase that unlocks Pro features such as full charge history, advanced analytics and widgets, including Pro features added later. Pro is tied to the Apple ID you bought it with; use Restore Purchases after reinstalling or on a new device. Family Sharing is not available.
• Tips (“Buy us a bubble tea”) are voluntary support and unlock nothing.
• Prices are as shown in the App Store. Apple handles payment, receipts and refunds; to request a refund, follow Apple’s process at reportaproblem.apple.com.
• Speed tests, the Dynamic Island and Bedside mode work without any purchase.

4. Disclaimer

Values and tips in the App are for reference only and are not professional advice or a quality guarantee. Do not rely on the App alone to judge whether a charger or battery is safe or faulty.

The App is provided “as is”. We try to keep values reasonable and the App stable, but we do not guarantee it is fully accurate, error-free or uninterrupted. To the extent permitted by law, we are not liable for any loss arising from using or being unable to use the App, including loss of devices, accessories or data.

5. Intellectual property

The App’s code, interface design, icons and text are owned by CompoundWater. The charge records and share cards you create are yours to use and share freely.

iPhone, Mac and Dynamic Island are trademarks of Apple Inc. The App is not affiliated with or endorsed by Apple.

6. Restrictions

• Do not reverse engineer, modify or redistribute the App.
• Do not use the App for any unlawful purpose.

7. Changes to the App

We may add, change or remove features at any time, or stop offering the App.

8. Changes to these terms

If these terms change, we will update the date at the top of this page. Continuing to use the App after a change means you accept the updated terms.

9. Governing law

These terms are governed by the laws of the Republic of China (Taiwan). The Taiwan Taipei District Court shall be the court of first instance for any dispute.
