Papryx Documentation
Official guide for installing, configuring, and utilizing the 100% offline, privacy-first PDF workstation for Windows & macOS.
Workstation Overview
Papryx is a high-performance desktop workstation engineered for Windows (64-bit) and macOS (Apple Silicon & Intel). Unlike traditional SaaS web tools that require uploading documents to remote cloud queues, Papryx executes 100% on-device on your computer hardware.
Zero upload delay or bandwidth throttling. Files open and save at local NVMe SSD speeds.
Fully functional with Wi-Fi disabled or in high-security air-gapped enterprise environments.

License Activation & Offline Grace
Papryx uses cryptographic digital signature validation (Ed25519) to enforce single-seat licensing without tracking document usage.
- Cryptographic Local Vault: License entitlements are stored securely in OS-native encrypted storage (Windows DPAPI / macOS Keychain Services).

- Machine Transfer: You can transfer your seat to a new computer by clicking Settings ➔ Deactivate License.
Seamless Auto-Updates & Continuous Delivery
Papryx Desktop features an enterprise-grade differential auto-update subsystem engineered to deliver silent updates without consuming massive network bandwidth or interrupting active workflows:
- Fastly CDN Differential Blockmaps: Instead of re-downloading the entire 300MB application, Papryx downloads only modified binary chunks (typically 5–20 MB), saving enterprise bandwidth.
- Zero-Latency Boot: Update checks are delayed 15 seconds after launch to ensure zero impact on instant cold-start application performance.
- Manual Menu Check: Users can manually check for the latest release at any time via Help ➔ Check for Updates... in the native menu bar.
- Data & License Preservation: All user preferences, recent files, and OS-native safeStorage license credentials (Windows DPAPI / macOS Keychain) persist automatically across updates.
