Off-Grid Solar Calculator works on your phone and does not send what you type to us or to anyone else. There is no account, no analytics, no advertising and no location access. The app has no internet permission.
Your projects (loads, battery, panel and cable choices), your unit setting and a count of saved reports are stored on the device only. If you turn on Android backup, Google may back these up to your own Google account under your own settings; we never receive them. You can export everything as a file or delete everything at any time in Settings.
We collect nothing. The app has no internet permission, so it cannot send data anywhere.
If you subscribe to Pro or buy the lifetime option, the purchase is handled by Google Play. Google Play Billing sends diagnostics to Google when the purchase screen is used. For Google Play's Data safety form we declare:
App info and performance > Diagnostics: collected, not shared, required.
We never see your payment details. We only learn from Google Play, on your device, whether Pro is active.
The app requests no permissions. In particular it has no internet permission and no location permission.
Peak sun hours and night-time low temperatures for the 100 bundled places come from NASA POWER monthly climatology (2001 to 2025) and are stored inside the app. The app never looks up your location.
The app is not directed at children under 13.
Open Settings > Delete all data. This removes every project and setting from the device. Uninstalling the app does the same. A Pro purchase is kept by Google Play and returns with Restore purchases.
If this policy changes, the new version will be published at the address above with a new date.
