What is a Non-Disclosure Agreement (NDA)?
A Non-Disclosure Agreement (NDA) is a contract in which one or both parties agree to keep specified information confidential and not share it with outsiders. It's commonly used before discussing sensitive business details, like product plans, customer lists, or financials. The NDA defines what counts as confidential, how it can be used, and how long the obligation lasts.
When to use it
- Before pitching an idea, product, or business plan to a potential investor or partner
- When hiring a freelancer, contractor, or employee who will see confidential information
- Ahead of merger, acquisition, or due-diligence conversations
- When sharing financials, customer data, or trade secrets with a vendor or consultant
- During early-stage talks with a co-founder or collaborator
- Before showing source code, designs, or prototypes to an outside developer or agency

Non-Disclosure Agreement (NDA) FAQs
Is an NDA signed online legally binding?
Yes. Under the U.S. ESIGN Act and UETA, and the EU's eIDAS regulation, electronic signatures are legally valid for most contracts, including NDAs. Each signature on tuyaform is backed by an audit trail and a Certificate of Completion recording who signed, when, and from where. As with any contract, both parties should sign willingly and understand the terms.
What's the difference between a one-way and mutual NDA?
A one-way (unilateral) NDA protects information shared by one party, like when you disclose plans to a contractor. A mutual (bilateral) NDA protects information flowing in both directions, which is common when two companies explore a partnership. You can edit the tuyaform template to fit either situation.
Is tuyaform really free?
Yes. tuyaform is free forever and ad-supported. You can create, send, and sign your NDA at no cost, and the signed PDF has no watermark. There's no trial and no per-document fee.
Do I need a lawyer to use this NDA?
Not necessarily. Many people use a standard NDA template for routine confidentiality without legal help. This template is a starting point and not legal advice, so for high-stakes deals or unusual terms, it's wise to have a lawyer review it before signing.
What proof do I get that the NDA was signed?
After everyone signs, you receive the completed PDF plus a Certificate of Completion. It records each signer's name, email, signing timestamp, and IP address, and the document is sealed so any tampering can be detected. This audit trail helps demonstrate the agreement's validity if it's ever questioned.
