Frequently asked questions

Are my files uploaded?

No. This tool runs entirely in your browser, so your files never leave your device. It even works offline once the page has loaded.

Is this a legally binding digital signature?

It's a visual signature: an image of your signature placed on the page, like signing a printout. It isn't a certificate-based (cryptographic) digital signature.

Where is my saved signature stored?

Only in your browser's storage on this device, if you choose to save it. You can remove it at any time with Clear my data.
