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 Windows DPAPI encrypted storage.
  • 14-Day Offline Grace Period: Once activated, Papryx operates continuously offline for up to 14 days without requiring any internet connection.
  • Machine Transfer: You can transfer your seat to a new PC 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 DPAPI license credentials persist automatically across updates.

Direct Text & Font Editor

Click and edit text inline on PDF pages with zero typographic baseline drift. Papryx matches existing fonts dynamically or allows substituting from 22 bundled offline font families:

Zero-Egress Network Verification Guide

IT departments and security officers can independently audit Papryx’s zero-egress architecture on any Windows PC:

# Step 1: Open Windows Resource Monitor
resmon.exe
# Step 2: Open Network tab and filter by Papryx.exe
# Step 3: Edit or convert a 100MB PDF document
Observation: Network Send (B/sec) = 0 B/s

All document manipulation occurs locally without opening any outbound socket connections to external hosts.
