1. Overview
Fast Mahjong Cards ("we," "our," or "us") respects your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information when you use our iOS app.
2. Information We Collect
We collect limited information needed to run the app, process purchases, and keep your cards available across sessions.
Information stored on your device
- Card designs, saved cards, and drafts
- Print quota and usage state
- Recently generated card fingerprints so you do not see the same card twice
- A stable device identifier used only for purchase restoration
Information processed by RevenueCat
We use RevenueCat to manage subscriptions, purchases, and Pro entitlements. RevenueCat may collect:
- Device type and operating system version
- Purchase history, subscription status, and transaction tokens
- Your app user ID or a stable device identifier
- Last-seen timestamp
See RevenueCat's privacy policy at revenuecat.com/privacy.
Information processed by Despia
Despia is the native runtime that bridges our web app to iOS features such as the RevenueCat paywall and haptic feedback. It processes your user agent and device environment so native calls can work, and it passes purchase and entitlement data between the app and RevenueCat.
Information stored in our backend
If you create an account, our backend (hosted on Lovable Cloud / Supabase) stores:
- Your user ID
- Pro entitlement status, product ID, and expiration date
- Purchase event history received from RevenueCat webhooks
We do not offer Google Sign-In, Apple Sign-In, or any other social login.
3. How We Use Your Information
- To generate, save, and print your Mahjong cards
- To track free print usage and unlock Pro features after purchase
- To restore previous purchases across app reinstalls
- To avoid showing you the same generated card repeatedly
- To process and validate subscriptions and one-time purchases
4. Data Sharing
We do not sell, rent, or trade personal information. We share only the limited data described above with our service providers (RevenueCat, Despia, and Lovable Cloud) so they can perform purchase handling and app hosting on our behalf.
5. Third-Party Services
The app uses the following third-party services:
- RevenueCat — in-app purchases and subscription management
- Despia — native iOS runtime and paywall bridge
- Lovable Cloud / Supabase — user accounts, entitlements, and webhook storage
- Google Fonts — font files loaded by the app
6. Your Rights and Choices
You can delete locally stored data at any time from theSettings screen, or by clearing the app's storage. If you have an account and want your backend data deleted, contact us at the email below.
7. Children's Privacy
The app is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
