2. Scope and overview
This policy covers information processed by us and relevant third parties when you use 24 Points: Math Challenge on iPhone and iPad (the app).
No registration or login is required; core math games and solving work offline. We operate no account or game server storing your puzzle records. The free version includes Pangle advertising, with an optional VIP purchase through Apple App Store. Local processing, ads and purchases are explained separately below.
3. Information processed on your device
| Information | Purpose | Storage |
|---|---|---|
| Hint balance | Calculate available hints | Stored in local app data |
| Sound, interaction audio and haptic settings | Remember your preferences | Stored in local app data |
| Last app-open ad time | Control app-open ad frequency | Stored in local app data |
| Current puzzle, input steps and some ad display timing | Run the current game and control display timing | Processed mainly in memory; not uploaded to us as account data |
| VIP purchase entitlement | Determine eligibility for unlimited hints and fewer ads | Transactions verified through Apple StoreKit; entitlements confirmed locally |
The app itself does not require your name, phone number, email or password, or read contacts, photos, camera, microphone, precise location or health data. If you email us, we process information you provide to reply and resolve the issue.
4. System permissions and tracking choices
The app may ask for cross-app tracking permission through iOS App Tracking Transparency (ATT). If permitted, advertising services may use IDFA within system permissions for ads and measurement. After refusal or withdrawal, IDFA should not be used for such tracking, but non-personalized ads may still appear. Manage permission in iOS Settings → Privacy & Security → Tracking.
Without relying on IDFA, advertising SDKs may still process necessary device and advertising information listed under Advertising and Third-party SDKs for ad display, connections and fraud prevention. ATT authorization does not mean all ads or third-party processing are disabled.
The app does not request location, notifications, photo library, camera, microphone or contacts permissions. Sound and haptics can be disabled in app settings.
5. Advertising and third-party SDKs
The free version may display app-open, banner and interstitial ads through the Pangle SDK, provided by Beijing Ocean Engine Network Technology Co., Ltd. and affiliates, for ad display, measurement, optimization, security and fraud prevention.
| Third-party services | Information that may be processed | Processing purposes |
|---|---|---|
| Pangle advertising SDK | Device model, OS version, language, time zone, network state, IP and inferred approximate region, app version and identifiers such as IDFV; IDFA with tracking permission; ad displays, clicks and conversions; crash and performance diagnostics, and sensor data needed for ad interaction | Ad display, measurement, optimization and fraud prevention |
The SDK may process this information directly from your device. See Pangle's policy for rules, retention and rights: https://www.csjplatform.com/privacy . We do not actively send puzzle input, hint balances or sound settings to the ad SDK. Third-party pages or apps opened from ads apply their own providers' policies.
VIP removes banner and interstitial ads and limits app-open ads to once per calendar day. VIP does not mean the app contains no advertising SDKs.
6. In-app purchases and VIP
VIP is an optional non-consumable one-time purchase, not a subscription, with no automatic renewal. Purchases, restoration, payment and refunds are handled by Apple App Store and require internet access.
Apple StoreKit verifies transactions and confirms VIP without giving us bank card details, payment account passwords or full Apple account information. Apple processes transactions and payments under its policy; refunds and revocations may update entitlements.
8. Retention and security
Hint balances, settings and app-open ad times stay in app data until cleared or uninstalled. Uninstalling usually removes local app data; backup copies follow iOS settings. Temporary game state and ad timing may reset when the app closes.
We have no account server storing the game data above. Pangle and Apple retain and protect their information under their own policies; we cannot delete their records directly. Inquiry emails are kept only as needed for requests and legal obligations.
We take reasonable measures to protect information we process, but no system is absolutely secure. Please also protect your device and Apple account.
9. Your choices and rights
Adjust sound and haptics in the app, refuse or withdraw tracking permission in iOS Settings, and uninstall to delete local data. No account closure is needed. Refusing tracking does not affect offline puzzles or solutions.
For information we process, you may lawfully request access, copying, correction, deletion or withdrawal of consent. For information handled directly by advertising SDKs or Apple, also consult their policies and account settings. Email us for assistance; we respond within 15 working days.
10. Minors
The app is not primarily directed at children under 14 and has no minor accounts. Minors should use it with guardian consent and guidance, especially when viewing ads or making in-app purchases.
Guardians with questions about minors' information may use the contact details on this page and manage tracking authorization and purchase restrictions in device settings.
11. Policy updates
We update this policy and its date when features, third-party services or legal requirements change. Significant changes are announced through app notices, release notes or similar means. We request renewed consent where legally required.
12. Contact and complaints
For questions, comments or complaints about this policy or processing, use the email and address at the top of the page. We will respond within 15 working days. You may also complain or report to competent authorities.
