Overview
Guest gameplay, puzzle progress, settings, streaks, unlocks, and saved games stay on your device. Signing in, cloud backup, purchases, social features, rewarded cosmetic offers, analytics, and diagnostics are optional and are used only when the corresponding feature is available and you choose to use it.
Sudoku Lumina does not sell personal information. It does not use interstitial or mid-puzzle ads, and it does not request App Tracking Transparency permission for optional non-personalized cosmetic reward ads.
Data we handle
On-device play
The app stores puzzle state, completion history, XP, streaks, settings, accessibility preferences, and earned cosmetics locally so play can resume offline.
Optional account and cloud backup
If you sign in, we process an account identifier and the gameplay, settings, unlock, entitlement, and sync data needed to provide backup and multi-device recovery. Analytics consent, diagnostics consent, and cellular-download choices remain device-local and are not restored from another device.
Optional purchases and rewards
Apple or Google processes payments. RevenueCat processes store transaction and entitlement records. If you explicitly start a cosmetic rewarded-ad offer, Google AdMob may process device, consent, ad-delivery, coarse-location, and fraud-prevention information. Lumina stores a one-way transaction digest and reward time to prevent duplicate or excessive grants.
Optional analytics and diagnostics
Usage analytics and crash diagnostics have separate controls and both default to off. Allowed events use controlled categories and coarse ranges. They exclude account IDs, email, free text, puzzle IDs, board contents, exact solve times, and exact mistake counts. Crash messages are reduced on-device to an approved category and reason code before transmission.
Player-initiated support reports
A support report is created only after you confirm. It contains app/build, platform, settings, aggregate progression, content/sync, and recovery-health information. It excludes identity, puzzle contents, saved games, tokens, secrets, file paths, and raw error text. The app opens the operating-system share sheet; it does not upload the report automatically.
Your choices and rights
- Play as a guest without creating an account.
- Enable or disable analytics and diagnostics independently in Settings.
- Export signed-in account data from Profile when cloud services are configured.
- Delete a signed-in account in the app or follow the account deletion instructions.
- Use store controls to manage or cancel subscriptions and restore qualifying purchases.
- Contact us to request access, correction, deletion, or another privacy right available where you live.
Deleting a Lumina account does not cancel an Apple or Google subscription. Guest data remains local until you clear app storage or remove the app.
Service providers
Depending on the features you choose and the release lane, Sudoku Lumina may use Apple App Store, Google Play, Firebase Authentication, Cloud Firestore, Cloud Functions, App Check, Analytics, Crashlytics, Performance Monitoring, Remote Config, RevenueCat, and Google AdMob. These providers process data under their own terms and our configured service instructions.
Social and leaderboard visibility defaults are restrictive. Public identity or share-card identity is not exposed unless you explicitly choose the relevant setting.
Retention and security
Local data remains until you clear it or remove the app. Signed-in cloud data remains while your account is active and is removed through the account-deletion flow, except records Apple, Google, or another processor must retain for security, fraud prevention, tax, or legal obligations. Opt-in analytics and diagnostics are configured for no more than 90 days.
We use platform authentication, App Check where available, encrypted save transport, least-privilege database rules, integrity checks, and duplicate-safe transaction receipts. No system can be guaranteed perfectly secure.
Children
Sudoku Lumina is family-friendly but is not directed to children under the minimum digital-consent age in their jurisdiction. We do not knowingly request a child's name, email, or public profile.
Changes to this policy
We may update this policy when the game, service providers, or legal requirements change. The effective date above identifies the current version. Material changes will be communicated in the app or through the public site where required.
