This Privacy Policy explains how we (“we”, “us”, or “the developer”) handle information in connection with the mobile applications we publish (collectively, the “Apps”). It applies to every App published under our App Store developer account, unless a specific App displays its own policy.
a. Content you create. Data you enter into an App stays on your device (and your iCloud, if enabled). It is not transmitted to us.
b. Usage & diagnostics. We use Google Firebase / Google Analytics to collect anonymous, aggregated information such as app launches, feature usage, session counts, device model, operating system version, language, coarse region, and a resettable app-instance identifier. We use this to understand how many people use the Apps and how to improve them.
c. Advertising. Some Apps display ads through Google AdMob. AdMob may collect device identifiers — including the Identifier for Advertisers (IDFA) only if you grant permission through Apple’s App Tracking Transparency prompt — to serve and measure ads. If you decline tracking, you still see ads, but they are less personalized.
d. Purchases. In-app purchases are processed by Apple. We receive confirmation that a purchase occurred; we never receive your payment card or billing details.
e. Account (some Apps only). Apps that offer cloud features may let you sign in with Sign in with Apple. This provides a stable, app-specific user identifier and, optionally, a private relay email, used to associate purchases, credits, or synced content with your account.
An App may request access to Photos, Camera, Calendar, Contacts, Notifications, or similar — always only when you use the related feature, and you may decline. Denying a permission does not block the rest of the App; only the specific feature is affected.
We share information only with service providers that help us run the Apps:
We do not sell your personal data, and we do not share the content you create with any third party.
Content stored on your device is removed when you delete the App (iCloud copies are removed according to your iCloud settings). Anonymous analytics and advertising data are retained by the respective providers according to their default retention periods.
The Apps are not directed to children under the age of 13 (or the minimum age required in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.
The Apps are offered in multiple regions, including the United States and China. By using an App you understand that anonymous analytics and advertising data may be processed by the providers named above.
We may update this Privacy Policy from time to time. The “Last updated” date above reflects the latest version. Continued use of an App after a change means you accept the updated policy.
