Wattwise Privacy Policy

Last updated: 7 November 2026 · Developer: Fablelamp Studio · App: Wattwise – Electrician Calculator (com.reliablecalculator.wattwise)

Wattwise is a set of electrical, energy and building-services calculators. It works offline and does not collect any personal data.

Data we collect

None. Wattwise does not collect, transmit, sell or share personal data. It has no user accounts, no advertising, no analytics and no crash-reporting SDKs. The app does not request any permission. The developer has no server that receives your data.

Data stored on your device

Your settings (theme, colour, units, wiring standard, language), favourite calculators, the last values you entered and, with Pro, your saved calculations are stored only in the app's private storage on your device. They are deleted when you uninstall the app or clear its data. If Android backup is enabled on your device, this storage may be included in your personal Google backup under Google's own privacy terms.

Sharing and PDF reports

"Share" and "PDF report" create the text or PDF file on your device and open Android's share sheet. What you send or save is handled by the app you choose; the developer never receives it.

In-app purchase

Wattwise Pro is a one-time in-app purchase processed by Google Play Billing under Google's own terms. The app only asks Google Play whether Pro has been purchased on your Google account; the developer receives no payment card details.

Children

Wattwise is a professional tool and is not directed at children.

Changes

If this policy changes, the new version will be published on this page with a new date.
