This Privacy Policy governs the manner in which the “Grammar Guru” mobile application (the “App”) collects, uses, maintains, and discloses information collected from users (each, a “User”) of the App.
This policy applies to the App and all products and services offered by Digital Update Per Min.
1. Personal Identification Information
We do not collect any personally identifiable information (PII) from our users. The app is designed to function completely offline without requiring any user registration, login, or personal data input. All user progress, including quiz scores, language preferences, and streaks, is stored locally on the user’s device using SharedPreferences. This information is not transmitted to our servers or any third parties.
2. Non-Personal Identification Information
We may collect non-personal identification information about users whenever they interact with our App. Non-personal identification information may include the device type, operating system, and other technical information about users’ means of connection to our App, such as the mobile network carrier used. This information is collected anonymously and cannot be used to identify you.
3. How We Use Collected Information
The “Grammar Guru” app uses user-collected information for the following purposes:
- To Improve App Functionality: We use non-personal data to understand how our users interact with the app, which helps us improve the app’s performance, design, and content.
- To Provide Offline Features: The app’s core data (quiz questions, lessons, etc.) and user-specific progress are stored on your device to ensure you can use the app without an internet connection.
4. Third-Party Advertising
Our app uses Google’s AdMob service to display advertisements. AdMob may collect and use information about your usage of this and other applications to provide advertisements about goods and services of interest to you. This may include your device’s advertising ID and other non-personal information.
- The data collected by AdMob is subject to their own Privacy Policy. You can read more about how AdMob uses data here: https://policies.google.com/technologies/ads
5. How We Protect Your Information
We adopt appropriate data collection, storage, and processing practices and security measures to protect against unauthorized access, alteration, disclosure, or destruction of your personal information, username, password, transaction information, and data stored on your device. Since all sensitive user data is stored locally on your device, it is not vulnerable to external data breaches.
6. Sharing Your Personal Information
We do not sell, trade, or rent users’ personal identification information to others. We may share generic aggregated demographic information not linked to any personal identification information regarding visitors and users with our business partners and trusted affiliates for the purposes outlined above.

Digital Update Per Min has the discretion to update this privacy policy at any time. We encourage users to frequently check this page for any changes to stay informed about how we are helping to protect the personal information we collect. You acknowledge and agree that it is your responsibility to review this privacy policy periodically and become aware of modifications.
8. Your Acceptance of These Terms
By using this App, you signify your acceptance of this policy. If you do not agree to this policy, please do not use our App. Your continued use of the App following the posting of changes to this policy will be deemed your acceptance of those changes.
