Effective Date: June 13, 2026

This Privacy Policy describes how Study Timer ("we," "our," or "us") collects, uses, and protects your information when you use our Android mobile application. We are committed to protecting your privacy and ensuring you have complete control over your study data.

Information Collection and Use

Study Timer is designed to be a privacy-first application. All of your personal study data is stored entirely locally on your device.

We do not require you to create an account, and we do not transmit, collect, or store your personal data on any external servers. The data saved on your device includes:

Study Logs: Session durations, timestamps, completion statuses, and daily streaks.

App Preferences: Your chosen timer durations (Study, Short Break, Long Break) and notification settings.

This information is used strictly within the app to calculate your daily summary, render statistical graphs, and track your study streaks.

Device Permissions

To provide its core functionality, Study Timer requests access to certain device features. The app only uses these permissions to enhance your local experience:

Notifications (POST_NOTIFICATIONS): Used exclusively to send local alerts when a Pomodoro session or break concludes, ensuring you are notified even if the app is minimized.

Prevent Device from Sleeping / Wake Lock: May be used to keep your screen active and ensure the timer functions accurately while you are in the immersive Landscape Focus Mode.

Third-Party Services and Libraries

Study Timer operates independently of third-party tracking. We do not sell, trade, or otherwise transfer your data to outside parties.

The application utilizes open-source libraries, such as MPAndroidChart, solely for the purpose of rendering on-device data visualizations (e.g., graphing your study durations over time). These UI libraries do not collect or transmit your data.

Data Retention and Deletion

Because all data is stored on your local device via a local database, you have complete control over your information.

Data Retention: Your data is kept for as long as you have the app installed on your device.

Data Deletion: You can permanently delete all your Study Timer data at any time by uninstalling the application or by clearing the app's data in your Android device's Settings (Settings > Apps > Study Timer > Storage > Clear Data).

Children's Privacy

Study Timer does not knowingly collect any personal information from children under the age of 18.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in our app features or legal requirements. We will notify you of any changes by updating the "Effective Date" at the top of this policy and, if necessary, providing a notice within the app. You are advised to review this Privacy Policy periodically for any changes.
