Privacy Policy for PDF Master
At PDF Master, we are committed to protecting your privacy and keeping your information secure. This Privacy Policy explains what we collect, how we use it, and the choices you have when using our mobile application (the "App").
1. Information We Collect
We do not collect or store personal information like your name, phone number, or the contents of your documents as part of normal App usage. Most App data stays on your device.
1.1 Device Permissions
To provide scanning and document management features, we may request permissions such as:
- Camera access (scan documents, capture images)
- Storage access (save, read, and manage files on device)
- Photo library access (import images from your gallery)
These permissions are used only for their stated purposes and can be revoked anytime in your device settings.
1.2 Usage Data
We may collect anonymized usage data to improve stability and performance, such as crash logs and feature usage analytics. This data is not intended to identify individual users.
2. How We Use Information
We use permissions and anonymized data only to:
- Enable scanning, image capture, and document processing
- Store and manage documents locally on your device
- Provide features like OCR and signatures
- Show advertisements (where enabled)
- Improve App stability and user experience
3. Data Storage and Security
Your scans and documents are stored locally on your device unless you choose to export or share them. We do not automatically upload your documents to our servers.
The App may create temporary files and cache during normal operation (for example, during image processing or PDF generation). These may be automatically cleared or can be cleared manually within the App.
4. Third-Party Services
4.1 Google AdMob
If ads are enabled, we may use Google AdMob to display ads. AdMob may collect device identifiers and usage information to serve ads (including personalized ads depending on your settings and region). Learn more in Google's Privacy Policy: https://policies.google.com/privacy.

We may use Google ML Kit for scanning and OCR features. ML Kit can process images locally on your device. For more information: https://developers.google.com/ml-kit.
