Privacy Policy

AlarmAmps: Battery & Voltage does not collect any data. No accounts, no analytics, no advertising, and no tracking of any kind. The app makes no network requests at all.

Your projects, devices and calculations are stored only on your iPhone.
The PDF submittal is generated on your device and handed to the iOS share sheet — we never see it.
We cannot see your data, because it never leaves your device.
Deleting the app removes all of its data from your device.

Purchases are processed by Apple. We never receive your payment details.

Full Unlock

AlarmAmps: Battery & Voltage is free to use. A one-time, non-consumable Full Unlock purchase ($4.99) unlocks the premium features. It is not a subscription and never expires. Restore it on a new device with Restore Purchase in Settings.

FAQ

Does it work offline? Yes — entirely. The app has no network code at all.

I paid but the features are locked. Tap Restore Purchase in Settings while signed in to the same Apple ID used for the original purchase.

Why do I type in the device currents? Because the app ships no device tables. You enter the standby and alarm current from your own datasheet, which is also more accurate — currents vary by model and revision.
