}FAQ
Does Constaia prove the document is authentic?
No. It checks the type, data consistency and your rules, and flags signals such as a possible edit or a screen photo. That does not prove authenticity.
Is a copy of the document kept?
No, unless you ask for it. With storage "none" (the default) the file is deleted when the analysis ends.
