Privacy policy

Last updated 2 September 2026 · Applies to Powernotch 1.0 and later

Data collected

None. Powernotch does not collect, store, transmit or share any personal data or usage data. It does not use cookies, identifiers, analytics, crash reporting or advertising frameworks. There is no account and no sign-up.

What the app reads on your Mac

To do its job, Powernotch reads the following information from macOS, locally on your Mac:

• The battery level, charging state and estimated remaining time of the Mac it runs on.
• The battery level, charging state and device name of accessories paired with your Mac, such as a Magic Keyboard, Magic Mouse, Magic Trackpad, AirPods, headphones and controllers.

This information is only used to display it on your screen and, if you enable it, to show a low-battery notification. It is never sent anywhere and is not written to disk, except for your own settings, which are stored in the app's sandbox container on your Mac.

Network access

Powernotch has no network access. It cannot send or receive data over the internet.

Permissions

• Bluetooth, required by macOS to read the battery level of wireless accessories. macOS asks for it once, at first launch.
• Notifications, optional, only if you turn on low-battery alerts.

Both can be revoked at any time in System Settings. Powernotch does not request Accessibility, Screen Recording, location, contacts, camera or microphone access.

Purchases

Powernotch Pro is an in-app purchase handled entirely by Apple through the Mac App Store. Powernotch never sees your payment details. Apple's own privacy policy applies to the purchase.

Children

Powernotch does not collect data from anyone, including children.

Changes

If this policy ever changes, the new version will be published at this address with an updated date.
