Solitaire: Proven Solvable ("the app") is a classic card game (Klondike and FreeCell) made by an independent developer. This policy explains what data the app handles.
The app has no account system, no registration, and no server of its own. Everything you build up while playing — your win rate, streaks, coins, unlocked card backs and tables, daily-deal progress, and your in-progress game — is stored only on your device and is never uploaded by us. We cannot see it, and we do not receive it.
The solver that verifies each deal is solvable, and the "Is this deal still winnable?" feature, both run entirely on your device. No game state is ever sent anywhere.
The mobile app shows ads served by Google AdMob: occasional interstitials after you win a game (never after a loss), and rewarded videos you may choose to watch to earn coins for cosmetic card backs and tables. There is no banner ad — the play area is never covered by advertising. AdMob may collect and process data to serve and measure ads, including:
Google's handling of this data is described in the Google Privacy Policy and How Google uses information from sites or apps that use our services.
Undo, hints, restart, new deal, and the "still winnable?" prover are always free and never require watching an ad. Rewarded videos are optional and only ever grant cosmetic items.
In regions where it is required, the app shows a Google-certified consent form (UMP) before serving personalised ads, and you can change or withdraw that consent at any time. On iOS 14.5+, the app asks for App Tracking Transparency permission; if you decline, ads are still shown but are not personalised using the IDFA.
The app offers a single one-time Remove Ads purchase (not a subscription). Payment is processed by Apple or Google; we never see your payment details.
The app is not directed at children under 13. We do not knowingly collect personal information from children.
You can reset all locally stored data by deleting the app. You can limit ad personalisation in your device settings (iOS: Settings → Privacy & Security → Tracking; Android: Settings → Google → Ads).
