This app is designed to work as an independent study companion. It does not require account registration and does not ask users to provide a name, email address, phone number, or password.

2. No Affiliation Disclaimer

30-Day Language Planner is an independent app. It is not affiliated with, endorsed by, sponsored by, or officially connected to Duolingo or any other language-learning platform.

All third-party names, trademarks, logos, and brands belong to their respective owners. This app does not copy third-party lessons, exercises, sounds, characters, logos, or protected content.

3. Information Stored Locally on Your Device

This local information is used to make the app work correctly, show your progress, and personalize your study plan.

The app currently does not sync this progress data to a developer-owned server. If you uninstall the app, local progress data may be deleted from your device.

4. Information Collected by Third-Party Advertising Services

This app uses Google AdMob to display advertisements. Google AdMob and related Google services may collect or process certain information from your device for advertising, analytics, fraud prevention, frequency capping, reporting, and ad performance purposes.

Depending on your device settings, region, consent choices, and Google’s advertising technologies, this may include:

5. How Information Is Used

Information handled by the app is used for the following purposes:

6. Advertising

This app displays ads through Google AdMob. Ads may include banner ads, interstitial ads, native ads, and app open ads.

AdMob may show personalized ads or non-personalized ads depending on your region, consent status, Google settings, and applicable laws.

You can manage ad personalization through your Google account and Android device settings where available.

Do not click ads repeatedly or fraudulently. The app does not encourage users to click advertisements.

7. Consent for EEA, UK, and Switzerland Users

For users in the European Economic Area, the United Kingdom, and Switzerland, Google may require consent for personalized advertising and related data processing. Where required, the app may show a consent message before displaying personalized ads.

If consent is not provided, the app may show non-personalized ads or limited ads, depending on Google AdMob behavior and applicable legal requirements.

8. Notifications

The app may allow you to enable local study reminder notifications. These reminders are used only to remind you about your language study plan.

You can disable notifications in the app settings or through your Android system settings.

9. Data Sharing

The developer does not sell your personal data.

The app may share or allow processing of ad-related information through Google AdMob and related Google services for advertising, reporting, fraud prevention, and compliance purposes.

10. Data Retention

Local progress and settings are kept on your device while the app remains installed, unless you reset progress inside the app if such functionality is available.

Uninstalling the app may remove locally stored progress and settings.

Advertising data handled by Google is retained according to Google’s own policies.

11. Security

The app uses standard Android local storage mechanisms for app settings and progress. No method of storage or transmission is completely secure, but reasonable measures are used to protect app functionality and user data.

This app is intended for general audiences and is not specifically directed to children.

If the app is later targeted to children or submitted under a child-focused audience category, the developer must review and comply with applicable Google Play Families policies and child-directed advertising requirements.
