Security & Privacy

Contracts, tax forms, and legal agreements are sensitive. Here is how PDFCAN guarantees confidentiality: by keeping your files right inside your browser.

In-Browser Client-Side Processing

  • PDF rendering, text detection, and font manipulation run directly inside your web browser.
  • Your PDF files never leave your device during editing — no remote server buffering or external parsing queues.
  • High performance 60fps rendering without waiting on network uploads or file conversion pipelines.

Signatures & Private Data

  • Drawn and typed digital signatures are stored in your browser's private storage (IndexedDB).
  • Signatures are rendered directly into the PDF's vector stream upon export.
  • No third-party tracking cookies or advertising pixels run on PDFCAN.

Zero Data Retention by Default

  • Documents edited anonymously in your browser stay isolated to your browser session.
  • Closing the tab or clearing browser data removes all local cached sessions.
  • Nothing you edit is ever used to train AI models or shared with third parties.

Encryption & Transit

  • All connections use TLS 1.3 with Strict Transport Security (HSTS) enabled.
  • When using cloud document backup (Pro/Team accounts), files are encrypted both in transit and at rest.
  • Account passwords are encrypted using scrypt hashing with cryptographic salts — plaintext passwords are never stored.
