Lintra Privacy Policy

Privacy Policy

1. Overview

Lintra is primarily an offline application designed for creating and working with drawing-based content.

User-selected images, drawing progress, app settings, and generated drawing-related data are processed and stored locally on the user's device.

The application does not require user registration, and no account or login is needed to use its functionality.

2. Personal Data Collection

Lintra does not require users to create an account or provide personal profile information.

The developer does not directly collect users' drawings, selected images, or other creative content through a developer-operated backend.

3. Data Processed on the Device

The app may locally process and store the following data on the device:

- images selected by the user

- drawing progress and drawing-related metadata

- language, theme, and other app preferences

- purchase status for optional Pro features

- notification-related settings

This data is generally stored in the app's private local storage on the user's device.

4. Payments and Google Play

Lintra may offer optional paid features such as Lintra Pro.

If the user chooses to make a purchase, the transaction is processed through Google Play.

Product details, localized prices, purchase verification, and payment-related processing may be handled by Google Play and related Google services in accordance with their own terms and privacy practices.

Lintra itself does not store users' full payment card details.

5. Internet and Network Use

Most core features of Lintra work locally on the device.

However, the app includes Internet permission and may use network access when required for platform-related services, including Google Play Billing and purchase functionality.

The developer does not use Internet access to upload users' drawings or personal creative content to developer-operated servers.

6. Printable Drawing Resources and Free Version Limit

Lintra may provide optional printable resources intended to help users prepare paper for drawing practice.

The app may offer downloadable PDF files containing dot patterns.

Users may print these files and connect the dots using a ruler and thin lines to create a drawing grid on paper before starting a drawing.

These printable resources are optional and are provided solely as drawing assistance materials.

In the free version of the app, the user may create one drawing.

Additional drawing functionality may be available through optional Pro features such as Lintra Pro.

7. Notifications

If the user grants notification permission, Lintra may display local reminders, progress-related notifications, or similar notifications on the device.

These notifications are used only to support app functionality and user experience and are not used for advertising or behavioral profiling.

8. Vibration

Lintra may use device vibration features to provide feedback during interaction.

This functionality is used only as part of the app experience.

9. Advertising, Analytics, and Tracking

Lintra does not display third-party advertising to users.

Lintra does not use behavioral tracking technologies for advertising or user profiling.

If analytics, crash reporting, or additional third-party services are introduced in future versions, this privacy policy may be updated accordingly.

10. Data Retention and Deletion

App data is generally stored locally on the user's device until it is deleted by the user.

Users may remove stored app data by deleting drawings within the app, clearing app storage in device settings, or uninstalling the application.

Because user content is stored locally, the developer may not be able to delete such data remotely.

11. Children's Privacy

Lintra is not intended to collect personal data from children.

Parents or guardians should review app permissions, stored data, and purchase settings before allowing children to use the app.

The app is intended for users aged 13 and older.

12. Changes to this Privacy Policy

This privacy policy may be updated from time to time.

If changes are made, the updated version may be provided within the app or through the app listing.
