Frequently Asked Questions

Why should I stamp documents as Confidential?

A Confidential watermark signals that the document contains sensitive information and should not be shared or distributed without authorization. It is common practice for legal contracts, financial reports, internal memos, and trade secrets.

Is the Confidential stamp legally binding?

A watermark alone does not create legal protection, but it establishes clear intent that the document was meant to be confidential. This can strengthen your position in confidentiality disputes or NDA enforcement.

Will the watermark obscure the text in my document?

No. The default opacity is 15%, which makes the watermark visible but transparent. You can adjust opacity from 5% (barely visible) to 50% (very prominent) depending on your needs.
