Questions

Are my files uploaded anywhere?
No. PDF Harbor runs entirely in your browser. Your files are read and processed on your device and are never sent to a server — you can check it in the counter on the home page or with your browser’s network tools.
Is my signature stored?
Only if you tick “Remember on this device”, and then only in this browser. You can stop it at any time.
Is this a certified digital signature?
No. It places an image of your signature on the page. It is not a certificate-based (eIDAS) signature.

They will be merged in this order, or continue with just one.
