Privacy Policy — Digit 3D
Summary: Digit 3D does not collect, upload, sell, or share personal data. It has no account system or developer-operated server. CAD files are processed locally on the device.
1. Overview
Digit 3D (the “App”) is an Android CAD viewing and modeling tool provided by the independent developer Digit 3D. The App does not collect, transmit, or share your personal information.
2. Information We Collect
None. The App has no user accounts, analytics, advertising, or tracking SDKs, and does not request the Android INTERNET permission.
3. Files and Local Data
- CAD files you open, import, create, or export are processed locally on your device and are not uploaded by the App.
- App settings, projects, and purchase/trial status are stored locally on your device.
- Exported files are saved only to a location you select.
- Uninstalling the App removes its locally stored app data.
4. Google Play Billing
Paid Pro unlocks are processed by Google Play Billing. The App does not collect, access, or store card numbers or other payment details. It receives only the purchase status/token needed to unlock features locally. Google Play processes billing data under Google’s own privacy policy.
5. Permissions
The App uses the system file picker to open and save files selected by you and the Google Play Billing permission for in-app purchases. It does not request location, contacts, camera, microphone, phone, or broad storage access.
6. Data Sharing and Security
The App does not share user data with third parties. Other than Google Play Billing for purchases you initiate, it integrates no third-party service that collects user data. Because files remain on your device and do not pass through a developer-operated server, you should use your device’s security features to protect them.
7. Children’s Privacy
The App is intended for general professional and engineering users, is not directed to children under 13, and does not knowingly collect information from children.
8. Your Choices
You can delete projects and files through the App or your device’s file manager. You can remove locally stored app data by uninstalling the App. Since the developer does not possess your data, there is no server-side access or deletion request to make.
9. Policy Changes
Material changes will be reflected on this page by updating the effective date and may also be announced through the App or its store listing.
