Privacy Policy

Last updated: September 4, 2026

The short version

AmpCalc has no accounts and no servers. Your calculator inputs and settings are stored only on your device. We cannot see them, sell them, or lose them, because they never reach us.

Data stored on your device

• The last inputs of each calculator (so screens reopen with your values).
• App settings (theme, unlocked status).

Nothing leaves your device. AmpCalc makes no network requests.

Purchases

In-app purchases are processed by Apple. We use RevenueCat to validate purchase receipts; it receives an anonymous app identifier and purchase status — never your inputs or personal details.

What we do NOT do

• No user accounts, no passwords, no email collection.
• No analytics SDKs, no advertising identifiers, no tracking.
• No ads.

Your control

Deleting the app deletes all data stored in it.
