Summary: Worksheet and paper data (settings, preferences, local PDFs, etc.) stays on your device and is not uploaded to the developer’s servers. There is no sign-in account. The app uses Google AdMob for app open ads (usually requires network). We do not add other analytics, statistics, or crash-reporting SDKs.
The Google Mobile Ads SDK (AdMob) may show ads on launch and when returning from the background. Google may process device- and ad-related technical data under its policies: Google Privacy Policy, Advertising & Google.
iOS: Use Settings → Privacy & Security to manage tracking, Apple Advertising, and related options (wording varies by iOS version).
Core features do not require children to register with the developer or submit personal identifiers. Ads are served by Google; parents should use system parental controls and the settings above as appropriate.
Core worksheet features do not require location, camera, microphone, or contacts. Saving or sharing PDFs may use system storage, share, or print. Uninstalling the app removes its sandbox data; back up PDFs you need first.
We will update the “last updated” date when this policy changes. Continued use means you acknowledge the update, except where stricter consent is required by law.
