An NDA and a timestamp do different jobs. The NDA records what someone promised about confidentiality. A timestamp dates the exact files you shared. TimeBinder® makes a fingerprint in your browser. The files stay on your device. You get a checkable Proof of Time Certificate that shows each exact file existed no later than a recorded time. It does not show who invented the idea, who owns it, or that the NDA is enforceable. Free to start. For pitch habits, see how to pitch an idea without it being stolen.

The routine: NDA, then timestamp, then send
- Agree and sign the NDA (or confirm their paper NDA) before you share detail. An e-sign tool such as SignNow (affiliate link) can collect signatures and an audit trail; it does not date the files you are about to share.
- Freeze the disclosure pack: deck, drawings, spec, or prototype photos you will send.
- Optional. Check hashes with the free SHA-256 hash checker.
- Timestamp the pack and, if you can, a PDF of the signed NDA. Your first Pooled TimeBind is free, with no credit card required.
- Save the Proof of Time Certificate with both.
- Then send the pack under the NDA.
How to timestamp a file has the steps. Manufacturer sends: before sending a product design to a manufacturer.
Why one without the other is thin
An NDA without a dated copy of what you showed leaves room to argue about scope. A timestamp without an NDA dates files but does not create confidentiality duties. Use both when the disclosure matters. This is general information, not legal advice. Have a lawyer review NDAs for your situation.
What a TimeBind shows, and what it doesn’t
A TimeBind shows that this exact file existed no later than the recorded time. It does not show authorship, ownership or copyright, and it does not replace an NDA, patent filing or trade-secret programme. See invention records timestamping and prior user rights records.
The same caution applies before unpublished details go into an AI tool. The free AI-assisted invention record checklist helps you review the exact files and terms to keep. It cannot decide inventorship, and it is not legal advice.

Yes, if you keep a copy of what was signed.

Does a timestamp make an NDA valid?
No. Validity depends on the agreement and applicable law.

Can the deck and NDA share one TimeBind?
Yes, up to 10 files.
-
What does it cost?
Your first Pooled TimeBind is free, with no credit card required. After that, from US$5; ASAP is US$15. See plans and pricing
