This Privacy Policy describes how Ng Cad ("we", "our", or "the App") handles your data. The App is built using the Capacitor framework and is designed to provide CAD/engineering tools.
1. Data Collection and Permissions
To provide its core functionality, the App requests access to specific device features. We want to emphasize that we do not collect your personal data on our own servers. Most data stays on your device.
Relevant Permissions:
•Storage & Filesystem (capacitor-filesystem): The App accesses your device's storage to save and load your CAD projects, drawings, and related documents. This is a core feature.
•Camera (capacitor-camera): If used, the camera is accessed only to allow you to take photos to attach to your projects or for visual reference within the App.
•Network & Connectivity (capacitor-network): We monitor your network status to ensure features requiring internet (like updates or cloud sync if applicable) function correctly.
•Notifications (capacitor-local-notifications): We use local notifications to provide status updates about your background tasks or reminders within the App.
•Haptics (capacitor-haptics): Used solely to provide tactile feedback (vibrations) during UI interactions to improve user experience.
2. Third-Party Services
The App may use third-party libraries or services that collect data to improve performance:
•Google Play Services: Used for app distribution, updates, and basic analytics. Google's Privacy Policy.
•Cordova Plugins: The App includes a Cordova plugin bridge for legacy support; these plugins operate under the same privacy standards as the main App.
3. Data Retention and Security
•Local Storage: All files created by you are stored locally on your device unless you manually share them.
•Security: We use standard Android security protocols to protect your data. Since we do not host your files on our servers, the security of your projects also depends on your device's security.
4. Children’s Privacy
Ng Cad is a family-friendly application. We do not knowingly collect or request any personal information from children.
5. Your Rights
Since your data is stored locally, you have full control over it. You can delete your projects at any time using the App's interface or your device's file manager. You can revoke permissions (Camera, Storage) via the Android System Settings at any time.
6. Changes to This Policy
We may update this policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
