Frequently Asked Questions

help_outlineWhat level of encryption is utilized?

We utilize standard 128-bit or higher encryption mapping, which is legally compliant for most commercial and personal securing requirements.

help_outlineIf I forget the password, can you recover it?

No. Because your file is processed locally and we keep zero logs on our end, a forgotten password means you will simply not be able to open that specific encrypted file.

help_outlineWill this prevent users from copying text?

Yes, applying an owner-level encryption password effectively renders the document unreadable and un-parsable to standard users without the key.
