This Privacy Policy describes how PowerGlass ("the app", "we", "us") handles your information. PowerGlass is developed by JZA Applications.

The data PowerGlass works with

To predict your battery life, PowerGlass records and stores on your watch:

• Battery readings. Your watch's battery percentage, charging state and power mode, sampled while the app runs in the foreground or background.
• Learned usage patterns. The hourly drain rates the app derives from those readings, kept as separate models for Standard and Low Power Mode.
• Your settings. Choices such as your watch model, learning speed, displayed data fields and complication layout.
• Achievement progress. Which milestones you have unlocked and when.

None of this identifies you, and none of it leaves your watch.

Where your data is stored

Everything PowerGlass records is stored locally on your Apple Watch. There is no PowerGlass account, no developer-operated server, and no copy of your data held by us. If you back up your devices, your PowerGlass data may be included in that backup, which is governed by Apple's terms and Apple's Privacy Policy.

Notifications

PowerGlass can ask for permission to show notifications, for example when you unlock an achievement. These are local notifications generated on your watch — nothing is sent to us or to any third party, and you can revoke the permission at any time in Settings.

Data we collect

We do not collect, transmit, sell, or share your personal data. Specifically, PowerGlass:

• Does not connect to the internet or transmit any data off your device.
• Does not use third-party analytics, advertising, or tracking SDKs.
• Does not maintain developer-operated servers that receive your data.
• Does not create user accounts with us or require you to provide an email or password.
• Does not access your location, health data, contacts, or any other personal information.
• Does not track you across apps or websites.

Children's privacy

PowerGlass is not directed at children and does not knowingly collect personal information from anyone, including children under 13.

Your control over your data

You can wipe everything the app has learned at any time with Settings → Reset All Data inside the app. Deleting the app removes all of its data from your watch.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date at the top.
