Frequently asked questions
How strong is the protection?
AES-256 encryption. Keep the password safe, because the document cannot be opened without it.
Can I limit printing and copying?
Yes. Choose which actions are allowed.
Are my files kept?
No. Uploads are removed as soon as the job finishes, and the finished file expires about an hour later. Nothing is sent to a third-party service.
