Summary: Learning data (practice progress, stroke-order and handwriting records, textbook preferences, local PDFs, etc.) is stored on your device only and is not uploaded to our servers; no account is required. We integrate Google AdMob to show app open (splash) ads (usually requires a network connection). We do not provide your practice or learning content to advertising providers. We do not integrate other analytics, statistics, or crash-reporting SDKs.
“We do not collect” above means the app developer does not actively collect, store, or transmit that information for learning features. Technical data related to ad delivery may be processed by Google as described in Section 2.
We use the Google Mobile Ads SDK (AdMob) to show app open ads, typically when entering the home screen after onboarding on cold start, or when returning to the app from the background after it has been away for an extended period. App open ads are not shown before first-time onboarding is completed. If an ad fails to load or times out, the app continues to the next screen without blocking use.
Google and its advertising partners may process data related to ad display and interaction (such as device identifiers, network information, and ad engagement) under their privacy policies. We do not provide your stroke-order, practice, or textbook content to advertising providers. See: Google Privacy Policy, Ads and data, AdMob program policies.
The app is configured for child-directed treatment and limits ad content maturity to G (general audiences), consistent with AdMob SDK settings.
iOS: You can manage tracking, Apple Advertising, and related options in Settings → Privacy & Security (wording may vary by iOS version). App open ads usually require a network connection; core stroke-order and practice features work offline on device.
Core features do not require children to register with us or submit identity information to the developer. Ads are provided by Google; parents and guardians should manage use with system parental controls and the settings described above.
Core stroke-order and practice features do not require location, camera, microphone, or contacts. Saving or sharing PDFs and playing pronunciations may use system storage, sharing, or audio capabilities. Uninstalling the app removes data in the app sandbox; back up important PDFs first.
We will revise the date on this page when we update this policy. Continued use means you acknowledge the update, except where separate consent is required by law.
