I do not collect, sell, or store personal information from users of the App. The App does not require an account, sign-in, email address, or other personal details.
The App may save your study progress, such as viewed grammar cards and memorization status, locally on your device. This information is used only to provide the App's study features and is not sent to me.
The App uses Google AdMob to show banner advertisements. Google and its partners may collect and use information from your device to provide, limit, measure, and improve advertisements. This may include device identifiers, advertising data, approximate location derived from your IP address, ad interaction data, diagnostics, and similar information handled by the Google Mobile Ads SDK.

Aside from Google AdMob for advertisement presentation, the App does not use third-party services to collect or share user information.
The App is suitable for general audiences, including younger language learners. I do not knowingly collect personally identifiable information from children.
I do not operate a server that stores your personal information for this App. Information handled by Google AdMob is governed by Google's privacy and security practices.
