# Security & Privacy Policy — PDF Converter & Scanner

PDF Converter & Scanner is built on a strict privacy-first architecture designed to protect confidential legal contracts, personal tax documents, medical records, and corporate data.

## On-Device Processing
- 100% Local Execution: Core utilities including document scanning, camera edge detection, PDF rendering, signature stamping, file compression, page reordering, merging, splitting, and password encryption run locally on your device.
- Zero Cloud Transmission: Documents processed with core on-device tools are never uploaded, streamed, or copied to any external server.
- Offline by Default: The application operates in Airplane Mode and in disconnected environments without requiring an internet connection.
- Local Execution: Core sensitive utilities including document camera scanning, real-time edge detection, PDF rendering, vector signature stamping, page reordering, merging, splitting, and password protection run locally on your device.
- Zero Cloud Transmission for Core Tools: Documents processed with core on-device tools are never uploaded, streamed, or copied to any external server.
- Offline Availability: Core on-device tools operate in Airplane Mode and in disconnected environments without requiring an internet connection.

## Account-Free Access
- No Sign-Up Barrier: You do not need to submit an email address, create a password, or register an identity to access all features.
- Local Sandbox Storage: All documents remain inside the application's isolated operating system sandbox protected by hardware-backed device encryption (Apple Secure Enclave / Android Keystore).
- Local Sandbox Storage: All documents remain inside the application's isolated operating system sandbox on your mobile device.

## Remote Conversion Security (Office & Web)
- Dedicated Stateless Workers: Converting desktop office files (.docx, .xlsx, .pptx) or web pages requires dedicated rendering engines.
- Strict Zero Data Retention: Uploaded files for conversion are kept in volatile memory only for the duration of the conversion process. As soon as the output is downloaded by your device, or after an automated 1-hour expiration timer, all temporary assets are permanently wiped.
- No Training on User Data: User documents are never stored, parsed for telemetry, sold to third parties, or used to train machine learning models.
## Backend Conversion Security & Automated Cleanup
- Dedicated Processing Workers: Converting desktop office files (.docx, .xlsx, .pptx), deep PDF file compression, web page capture, and damaged PDF repair are processed via dedicated backend conversion engines over encrypted TLS connections.
- Automated Zero Permanent Retention: Uploaded files for conversion are kept in temporary storage strictly to complete the requested job and allow your app to download the result. An automated Janitor cleanup service continuously purges expired temporary files and completed jobs within 24 hours.
- No Training on User Data: User documents are never permanently stored, inspected, sold to third parties, or used to train artificial intelligence or machine learning models.

## Encryption & Compliance
- AES-256 standard encryption for protected PDF files, readable across standard viewers (Adobe Acrobat, Apple Preview, web browsers).
- Biometric protection support (Face ID, Touch ID, Android Biometric Prompt) for opening locked documents within the local viewer.
- Full compliance with Apple App Store Review Guideline 5.1.1 and Google Play Developer Program policies.
## Encryption Standards
- Standard password protection for PDF files, readable across standard viewers (Adobe Acrobat, Apple Preview, Google Drive, web browsers).
