Privacy Policy

Denttis Brush Timer collects only the minimum information necessary to provide its features.

• Name — used to personalise your greeting in the app
• Email address — used as your local account identifier
• Password — stored as a SHA-256 cryptographic hash; your plain-text password is never stored

• Brushing session records — date, time, and duration of each completed session
• Streak and usage data — calculated from your session history

• To create and manage your local account on this device
• To display your brushing streak, weekly progress, and total sessions
• To personalise your in-app experience with your name

We do not use your information for advertising, analytics, or any purpose beyond operating the app features described above.

• All data is stored locally on your device using Android Room (SQLite) database
• Your password is hashed with SHA-256 and is never stored in plain text
• No data is transmitted to any server, cloud service, or third party
• Data remains on your device unless you uninstall the app, which deletes all local data

We do not share, sell, rent, or transmit your personal data to any third party, advertiser, or external service. This app has no network permission and cannot transmit data even if it wanted to.

Denttis Brush Timer does not integrate any third-party SDKs, analytics tools, advertising networks, or crash-reporting services. The app is entirely self-contained.

This app does not knowingly collect personal information from children under the age of 13. The app can be used by children under parental supervision, and all data remains on the device.

If you believe a child has created an account without parental consent, you may delete the app to remove all associated data.

As this app stores no data on external servers, all data rights are exercised directly on your device.

Data is retained on your device for as long as the app is installed. Uninstalling the app removes all data permanently. There is no backup or cloud copy of your data.

We may update this Privacy Policy from time to time. Any changes will be reflected in an updated version of this document published with the app update on Google Play. We encourage you to review this policy periodically.
