Privacy Policy - Secure PDF Print & Decrypt

This Privacy Policy describes how Secure PDF Print & Decrypt ("we", "our", or "the app") handles your personal data and documents. We are committed to protecting your privacy and ensuring you have complete control over your sensitive files.

1. Summary: Zero Personal Data Collection

🛡️ Strict Local-Only Policy

All PDF unlocking, password verification, rendering, printing, and file export operations happen exclusively on your device in volatile memory (RAM). We do not upload, collect, transmit, or store your documents, passwords, or personal details on any remote servers.

2. Information We Process on Your Device

PDF Files: Files selected by you or shared to the application are loaded into local memory solely to render pages, remove encryption as requested, and send print jobs to your chosen print service.
Passwords: Passwords entered to unlock documents are used exclusively in temporary device memory for cryptographic decryption and are wiped as soon as the session ends or when the file is closed. Passwords are never saved or sent anywhere.

3. Third-Party Services & Advertising

The app uses Google AdMob to display banner and interstitial advertisements to support ongoing development.

Google AdMob may collect and use standard device identifiers (such as Android Advertising ID), coarse location, or app interaction data in accordance with Google's Privacy Policy to serve relevant ads and prevent ad fraud.

For more details on how Google processes ad data, please review: Google Ad Policies & Privacy

4. Device Permissions

The app requests the minimum permissions necessary to function:

INTERNET & ACCESS_NETWORK_STATE: Required by the Google AdMob SDK to load advertisements. PDF processing functions fully offline without requiring an active internet connection.
Storage / Media Access: Allows you to pick PDF files from your device and save exported decrypted documents via the system Storage Access Framework.

5. Data Security

Your documents never leave your device. The app adheres to the Android security model and uses secure in-memory buffers that are cleared when you navigate away or close the application.

6. Children's Privacy

Our application is not directed to children under the age of 13. We do not knowingly collect personal identifiable information from anyone.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
