Questions

Is this a legally binding signature?

It adds an image of your signature, accepted for many everyday documents. It isn’t a certificate-based digital signature.

No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
