Frequently Asked Questions
Q: Is an in-browser electronic signature legally binding?
Yes. Under the US ESIGN Act, the EU eIDAS regulation, and common contract law, an electronic symbol or signature adopted by a person with the intent to sign a document is legally recognized for most agreements.
Q: Is my signature or document sent to any server?
Never. ToolNexus operates entirely in your browser memory. Your contract and handwritten signature never leave your device.
