Common questions

Does Proofrun run real code?

Yes. Python, JavaScript, Node.js, SQL, HTML/CSS, React and PHP run on your phone, offline. On Android, Java, C and C++ also run on the device.

C or C++ says it needs a newer "Android System WebView"

The C/C++ compiler needs a recent version of Android System WebView. Update "Android System WebView" (and Chrome) in Google Play, then reopen Proofrun.

Are lessons in my language?

The app and its menus are translated. Lessons are in English for now.

I bought Pro but it is not unlocked

Open the Pro screen and tap Restore purchases, signed in with the same Google or Apple account you bought with. If it still does not unlock, email us with your order ID.

How do I cancel Pro?

In Google Play: Payments & subscriptions → Subscriptions. On iPhone: Settings → your name → Subscriptions. Uninstalling the app does not cancel it.

Will I lose my progress?

Progress is stored on your phone. Uninstalling the app or clearing its data removes it.
