Frequently asked questions
Is this a legally binding signature?
It adds the image of your signature to the page. Whether that is sufficient depends on the document and your jurisdiction; it is not a certificate-based digital signature.
Is my signature stored?
No. Signing happens in your browser and nothing is uploaded.
