Frequently Asked Questions

Does a watermark legally protect confidential content?

No - a watermark is a visual notice, not legal protection. Real protection requires NDAs, password-protection, and access controls. The watermark serves as evidence that the recipient was put on notice of confidentiality (useful in legal disputes about unauthorized sharing).
