🔒 Your Privacy is Our Priority

Enlyzr is designed with privacy at its core. Your personal data stays on your device, and we never collect or transmit your activity information without your explicit consent.

1. Information We Collect

1.1 Personal Activity Data

Enlyzr stores all your activity data locally on your device, including:

  • Activity entries (titles, values, categories, timestamps, comments)
  • Custom categories and measurement units
  • Routine configurations and completion history
  • App settings and preferences
  • Exported data and backups (when created by you)

1.2 Technical Information

The application itself does not collect any technical information automatically. We only receive technical information when:

  • You experience an issue and choose to share details with us via email
  • You manually include app version, device model, or error logs in your support request
  • You explicitly consent to share diagnostic information for troubleshooting

Important: No automatic crash reporting, analytics, or usage statistics are collected by the application.

1.3 Location Data

Location services are entirely optional and used only for:

  • Calculating sunrise and sunset times for calendar features

You can use Enlyzr fully without enabling location services.

2. How We Use Your Information

2.1 Local Processing

All your activity data is processed locally on your device to:

  • Display your activities in various views and calendars
  • Generate analytics and insights
  • Send routine reminders and notifications
  • Create exports and backups when requested

2.2 App Improvement

Technical information (if shared) helps us:

  • Fix bugs and improve app stability
  • Optimize performance across different devices
  • Develop new features based on usage patterns
  • Ensure compatibility with Android updates

3. Data Sharing and Disclosure

🚫 We Do Not Sell Your Data

Enlyzr never sells, rents, or trades your personal information to third parties for commercial purposes.

3.1 When Data Leaves Your Device

Your data only leaves your device in these specific circumstances:

  • Manual Exports: When you choose to export data to external storage or share it
  • Cloud Backups: When you manually configure cloud storage backups
  • Support Requests: When you voluntarily share data with our support team via email

3.2 Third-Party Integrations

If you choose to use third-party integrations:

  • Cloud storage services (Google Drive, Dropbox) - only for backups you create

Each integration requires your explicit permission and can be disabled at any time.

4. Data Security

4.1 Local Storage Security

Your data is protected through:

  • Android's built-in app sandboxing
  • Encrypted local storage where your data is stored on the device (if device supports it)
  • Sensitive content masking and privacy controls

4.2 Export and Backup Security

When you create exports or backups:

  • You control where files are stored and who has access

5. Your Privacy Rights

5.1 Data Control

You have complete control over your data:

  • Access: View all your stored data within the app
  • Export: Create copies of your data in multiple formats

  • Significant changes will be announced through in-app notifications
