Frequently Asked Questions

Is this a legally binding electronic signature?

PrivaTools creates a visual signature embedded in the PDF. Whether it is legally binding depends on your jurisdiction. For most informal agreements and internal documents, it is widely accepted.

Can I sign multiple pages?

Yes. After creating your signature, you can place it on any page by navigating through the document preview.

Is my signature stored on the server?

No. Your signature exists only in your browser session. The server never stores signatures — it only applies them to the PDF during processing, then deletes the file within minutes.
