Question 1

Are my files uploaded to a server?

Accepted Answer

No. Yoomey runs the entire process inside your browser using WebAssembly and JavaScript. Your file is read into your device’s memory, processed there, and handed back to you as a download. We never receive it, so we cannot see, store or leak it — you can even disconnect from the internet after the page loads and the tool keeps working.

Question 2

What encryption is used?

Accepted Answer

AES-256 (PDF 2.0 / revision 6 security handler), the strongest standard PDF encryption, supported by all modern PDF readers.

Question 3

What if I forget the password?

Accepted Answer

We never see your password, so we cannot recover it. Keep a copy somewhere safe, such as a password manager.

Question 4

What do the restrictions do?

Accepted Answer

Restrictions (no printing, no copying) are honoured by compliant PDF readers. The open password is what actually protects the content.
