This Privacy Policy describes how Techtenstein Services Pvt Ltd ("we," "us," or "our") collects, uses, and shares your information when you use the AR Drawing: Pencil Sketch Art mobile application (the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.
To provide a functional and creative experience, we may require access to certain features on your device. All personal data processed is handled with high standards of security.
Camera Access (AR Features): The app requires camera access to enable Augmented Reality tracing. The camera feed is used for real-time image projection on your screen to help you sketch. We do not record, store, or transmit your live camera feed to any external servers.
Media and Storage: We require permission to access your device’s gallery. This allows you to select photos for tracing and to save your completed artwork or downloaded 4K wallpapers directly to your device.
Device Information: We may collect non-identifying information such as device model, operating system version (e.g., Android 16), and unique device identifiers for performance monitoring and advertising purposes.
The Service integrates third-party libraries to provide monetization and analytics. These third parties may collect data (such as IP addresses and Advertising IDs) according to their own privacy policies:
Google Play Services: Used for core app functionality and security.
AdMob & Facebook (Meta) Audience Network: Used to serve personalized and non-personalized advertisements within the app.
Firebase Analytics: Used to monitor app performance, crash reports, and user engagement trends.
Our app provides a library of high-definition and 4K wallpapers. When you browse or download these assets, the app may cache data locally on your device to ensure smooth performance and minimal battery impact.
Our Services are not intended for children under the age of 13. We do not knowingly collect personally identifiable information from children. If we become aware that a child under 13 has provided us with personal data, we will take immediate steps to delete it.
Depending on your location (e.g., GDPR in Europe or CCPA in California), you have rights regarding your data:
Opt-Out: You can opt-out of personalized advertising through your Android device settings (Settings > Google > Ads).
Data Deletion: You can remove all locally stored data by clearing the app cache or uninstalling the application.
If you have any questions, concerns, or requests regarding this Privacy Policy or our data practices, please reach out to us:
