Privacy Policy

Last updated: 16/05/2025

Introduction

Zentra ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data when you use the Zentra mobile application (the "App").

Information We Collect

Account Information

  • Authentication Data: When you sign up or sign in, we collect your email address, name, and authentication tokens. Passwords are securely managed by Supabase Authentication and never stored as plaintext.
  • Profile Information: We store your display name and optional profile picture.

Device and App Usage Data

  • Installed Apps: The App collects a list of installed applications on your device, including package names and icons. This data remains on your device and is not transmitted to our servers.
  • App Usage Statistics: We collect screen time data, including total usage time, most-used apps, hourly usage patterns, and app launch counts. This data is stored locally on your device by default.
  • App Blocking Schedules: Your created app blocking schedules, including schedule names, active days, time ranges, and lists of blocked apps are stored locally.

Local Settings

  • Preferences: We store your app settings locally, including theme preferences (dark/light mode), notification settings, and minimalist mode configuration.

Optional Cloud Data

If you choose to enable cloud sync:

  • Usage Statistics: Your usage data can be synced to your personal Supabase account according to your sync preferences.
  • Chat Messages: Messages and attachments sent to the AI Chat Assistant (beta feature) are processed through our Supabase Edge Functions and stored in our database.

Technical Information

  • Device Data: We collect non-personal device information such as device model, operating system version, and language settings to provide app functionality.
  • Diagnostic Data: The App collects error logs and performance metrics for troubleshooting, but these remain on your device unless you explicitly share them with us.

How We Use Your Information

  • Core Services: To provide app blocking, time tracking, launcher functionality, and AI assistance.
  • Personalization: To customize your app experience based on your preferences.
  • Device Synchronization: To sync your data across multiple devices if you enable cloud sync.
  • Service Improvement: To analyze aggregate usage patterns and diagnose technical issues.

Data Storage and Security

  • Local Storage: Most data is stored securely on your device using encrypted local databases (SQLite) and shared preferences.
  • Cloud Storage: If enabled, your synced data is stored in Supabase with industry-standard security practices:
    • Data is encrypted in transit using HTTPS/TLS
    • Supabase provides encryption for data at rest
    • Row-level security policies ensure you can only access your own data

Data Sharing

We do not sell or rent your personal information to third parties. We may share data with:

  • Service Providers: We use Supabase for authentication, database, and edge function services (when cloud sync is enabled).
  • Google Generative AI: If you use the AI Chat Assistant (beta), your chat messages are processed by Google's AI services.
  • Legal Requirements: We may disclose information if required by law or to protect rights and safety.

Your Rights and Choices

  • Account Control: You can access and update your profile information in App Settings.
  • Local Data: You can clear all locally stored data from App Settings.
  • Cloud Data: You can delete your account and all associated data by using the "Delete Account" option.
  • Permissions Control: You can enable or disable permissions (notifications, usage access, etc.) at any time.

Optional Features and Permissions

The App requires certain device permissions to function properly:

  • Android: Usage access (for screen time tracking), overlay permission (for app blocking), accessibility service and notification access (for app blocking functionality)

All these permissions can be managed through your device settings or within the App.

Third-Party Services

The App uses several third-party libraries and services, including Flutter packages for UI components and device functionality. These services may collect limited technical information as described in their respective privacy policies.

Children's Privacy

Our App is not intended for children under 13. We do not knowingly collect personal information from children under 13.

Changes to This Privacy Policy

We may update this Privacy Policy periodically. We will notify you of significant changes through the App or via email. Your continued use of the App after changes indicates your acceptance of the updated policy.
