Frequently asked questions
How secure is the encryption?+
We use AES-256, the same standard trusted by banks and governments.
What if I forget the password?+
We never see or store your password, so we can’t recover it. Keep it somewhere safe.
Can I stop people from printing or copying?+
Yes. Turn off printing or copying in the permissions. Note that some PDF readers ignore these restrictions.
