Frequently asked questions
How safe is the password protection?
It uses AES-256, the standard used by banks. A long password that is not a dictionary word is the main thing that keeps it safe.
What if I forget the password?
There is no way to recover it, not even for us, because we never see it. Keep it somewhere safe.
Can I stop people from printing?
Yes, untick "Print it". Note that some viewers may not respect every restriction, so the password is your real protection.
Do I send my password to a server?
No. Everything happens inside your browser.
