Privacy Policy
Last updated: August 19, 2026
Wattoo collects no personal data. None. It's that simple.
The app runs entirely on your device: no account, no server, no usage analytics, no advertising, no trackers.
Your calculations and diagrams
Everything you create in Wattoo — calculations, electrical diagrams, PDF exports — is stored only on your device. Nothing is transmitted, nothing leaves your iPhone or iPad. If you delete the app, this data is deleted with it.
Purchases
The subscription and the lifetime purchase are handled exclusively by Apple, through the App Store. Wattoo never sees your payment information. Purchase management and refunds are governed by the App Store terms.
Network
Wattoo contacts no third-party server. The only network communication is Apple's own purchase validation (StoreKit), handled by the operating system.
Children's data
Since the app collects no data at all, no data about children is collected either.
Changes
If this policy ever changes — for instance if a future version added an online feature — this page will be updated before that version ships, with the date shown at the top.
