Privacy Policy & File Security

1. Client-Side Processing by Default

Whenever technologically feasible (such as in Merge PDF, Split PDF, Rotate PDF, JPG to PDF, CV Builder, and Measurement Converters), all data processing executes 100% inside your local web browser using WebAssembly and HTML5 Canvas.

Your files never travel over the internet to our servers for client-side operations. They remain securely inside your computer or mobile device memory.

2. Automated Ephemeral Server Processing

For advanced operations requiring server-level engines (such as PDF to Word, LibreOffice conversions, or Tesseract OCR), files are transmitted over encrypted TLS connections to an isolated sandbox environment.

• Files are assigned random, non-guessable UUIDs.
• Documents are permanently and immediately erased the moment your download starts.
• An automated cleanup daemon continuously scans and purges any orphaned temporary files older than 15 minutes.
• We never read, inspect, archive, or train AI models on user documents.

3. No Accounts & No Tracking

Public users do not create accounts, passwords, or profiles to use UFK Tools. We do not track your identity across sessions or sell advertising profiles to third-party data brokers.
