How These Games Handle Data
We keep the data model intentionally small:
- Local gameplay data: puzzle progress, preferences, streaks, and purchased entitlements are stored on your device.
- Anonymous product analytics: TelemetryDeck is used to understand aggregate usage, such as puzzle completions, hint use, theme selection, widget use, and navigation flows.
- Optional Apple platform features: some games integrate with Game Center and iCloud when you choose to use those services.
What We Collect
- app opens, screen views, and session-level usage
- puzzle start, completion, solve time, move count, and hint usage
- difficulty, theme, widget, and feature usage
- basic technical context such as app version and device class
- No name, email address, phone number, or contact list
- No location data
- No advertising identifiers and no ads SDK
- No payment card or billing details
- No social graph, contact uploads, or personal profile data created by us
Apple Services Used by Optional Features
Game Center
If you sign in to Game Center, Apple may process your Game Center account data so leaderboards and achievements work. We use Game Center for gameplay features such as:
- leaderboards
- achievements
- player ranking and profile display inside Game Center UI
We do not receive your Apple account password or payment data.
iCloud Sync
Some iOS games optionally use Apple cloud services to sync progress or statistics across your devices:
- CloudKit: for puzzle progress where cloud sync is supported
- NSUbiquitousKeyValueStore: for lightweight statistics sync in some titles
If iCloud is unavailable or disabled, the games continue using local storage only.
StoreKit
In-app purchases are handled by Apple via StoreKit. We only receive the entitlement result needed to unlock paid content.
Local Storage on Your Device
- Preferences and consent: stored in on-device settings storage such as UserDefaults
- Puzzle progress and state: stored locally in app-managed on-device databases or persistence containers
- Purchase state: derived from StoreKit entitlements and local app state
Your Choices
- Analytics: disable analytics in Settings where that control is exposed
- Game Center: sign out of Game Center in the app or in Apple settings
- iCloud: disable iCloud for the app or disable iCloud on the device
- Local data: deleting the app removes the local app data stored on that device
Data Retention
- Local device data: remains until you delete it or remove the app
- TelemetryDeck analytics: retained under TelemetryDeck's service retention policies
- Apple service data: governed by Apple's own platform terms and retention policies

No Advertising or Personal Data Resale
We do not sell personal data. We do not use ad networks, ad attribution SDKs, or cross-app advertising profiles in these puzzle games.
Children's Privacy
These puzzle games are intended for a general audience. We do not knowingly collect personal information from children. The analytics described above are product-level usage signals, not personal profiles.
Your Rights
Depending on your region, you may have rights such as access, deletion, or objection. Because these games are mostly local-first and analytics are anonymous, the practical controls are usually:
- turn analytics off in Settings
- disable Apple platform services you do not want to use
- delete local data by removing the app or resetting in-app progress where available
Security
- network calls use the underlying platform transport security protections
- Apple handles payment processing and account services on its own systems
- local device storage is protected by the iPhone or iPad security model

If data practices change, this page will be updated and the "Last Updated" date will change.
