NDA redaction is the removal of party PII from a non-disclosure agreement. A trade secret only qualifies if its holder takes reasonable measures to keep it secret. That is the test in 18 U.S.C. §1839(3) and in Art. 2(1)(c) of Directive (EU) 2016/943. anonym.plus runs offline, so the clauses stay reusable.
When this applies
You want to reuse a signed form as a template or precedent. Uploading it to a cloud tool is itself a disclosure, and disclosure is what the §1839(3) reasonable-measures test weighs. So you clear both parties on your own machine.
How anonym.plus handles it
- Load the file into anonym.plus on your device.
- The tool flags both parties' names, titles, and contacts.
- It scans the header and signature block, not just the body.
- Confirm the flags and keep any defined term.
- Swap or black out the IDs.
- Save the clean template on your machine.
What you need to provide
- The signed form (PDF, DOCX, or scan).
- An operator; Replace keeps the clauses readable.
- Optional allow-list to keep your firm's boilerplate.

Limitations & cautions
Recitals, defined terms, and exhibits can name a party indirectly. OCR helps with scans, but check signed copies with care. A sector clue plus a date can still narrow the field, so review the result.
Frequently asked questions
How does redaction help protect a trade secret?
The law guards a secret only where its holder takes reasonable measures. Keeping the form on your own device is one such measure. Handing it to a third party is not.
Can I turn a signed NDA into a clean template?
Yes. Swap each party ID for a role label like [DISCLOSER]. The clauses stay, so the form is ready to reuse with new parties.
Does removing names weaken the duty of confidence?
No. That duty binds the named parties in the signed original, which you keep. The clean copy is a precedent, never a substitute for the executed one.
