Use a one-way (unilateral) NDA when only one party is sharing confidential information. Generate, send and sign — all free.
A one-way NDA binds only the receiving party to confidentiality. It's the right format when you're disclosing trade secrets, financials, source code or product plans to someone who isn't sharing back.
A one-way NDA binds only the receiver. A mutual NDA binds both parties. Choose one-way when only one side is disclosing.
Confidentiality typically survives 2–5 years after the agreement ends. Trade secret protections can last indefinitely.
