Frequently Asked Questions
Can I recover a forgotten password?

Are my documents uploaded to a server?
No. Everything runs strictly locally via JavaScript in your browser.
Security & Privacy
100% Secure & Private. The PDF is encrypted entirely within your browser's local memory using military-grade encryption algorithms. Neither the document nor the password is ever sent to any remote servers.
