## Summary
CircuitChef: One-Minute Repair is a mobile puzzle game. Version 1 has no backend server, no advertising SDK, no analytics SDK, and no external payment method. Gameplay progress and game settings are stored locally on the player's device. Digital purchases are processed by Google Play Billing.
## Information The App Stores Locally
The app may store the following information on the player's device using local app storage such as SharedPreferences:
- level progress, stars, best remaining time, and unlocked levels;
- coin balance and optional assist item counts;
- unlocked cosmetics and selected cosmetic settings;
- sound, haptic, and local debug purchase settings;
- locally delivered Google Play purchase entitlements;
- local purchase audit entries containing product ID, event type, delivery state, purchase ID when supplied by Google Play Billing, timestamp, and an optional status message.
This local information is used only to run the game, restore local state, deliver optional purchases, and show gameplay progress. The app does not send this information to a CircuitChef backend in version 1 because no backend exists.
## Purchases And Subscriptions
All digital goods are sold through Google Play Billing when the app is distributed on Google Play. CircuitChef does not provide external payment links or alternative payment flows for digital goods.
The app supports five consumable coin packs:
- `coins_1000`
- `coins_5500`
- `coins_12000`
- `coins_30000`
- `coins_70000`
The app supports three independent weekly subscriptions. These subscriptions can be active at the same time because each one is a separate Google Play subscription product:
- `circuit_club_weekly`
- `bench_club_weekly`
- `helper_club_weekly`
Google Play may process payment information, purchase tokens, subscription state, renewal, cancellation, and refund information according to Google's own policies. CircuitChef version 1 does not operate a backend purchase verification service and does not receive payment card details.
## Data Collection And Sharing
CircuitChef version 1 does not collect personal data through a developer-operated backend. The app does not include ads, ad measurement, third-party analytics, or social login.
Google Play and Android system services may process data needed for app distribution, purchases, crash handling, security, and billing according to Google's terms and privacy policy. CircuitChef does not sell personal data.
## Children And Target Audience
CircuitChef is a general-audience puzzle game and is not specifically directed to children. The game does not contain gambling, real-money rewards, ads, or user-generated public content.
## Data Retention And Deletion
Local gameplay data remains on the device until the player clears app data or uninstalls the app. Google Play purchase and subscription records are managed by Google Play. Players can manage subscriptions, cancellation, and payment methods through Google Play.
## Security
The app stores version 1 game state locally. Because version 1 has no backend, subscription and purchase entitlements are delivered client-side after Google Play Billing events. A backend verification service may be added in a future version for stronger purchase security.
## Changes To This Policy
This policy may be updated when the app changes. Material changes should be reflected in the app listing or in-app disclosures.
