NDA vs. Confidentiality Agreement — What's the Difference?
NDA and confidentiality agreement usually mean the same contract family. Here is how people use the labels — and what actually matters in the text.

In everyday business English, “NDA” and “confidentiality agreement” point at the same kind of contract: a promise not to misuse or spread confidential information. The title on page one matters less than the definitions, purpose, duration, and who is bound.

How the labels get used
- NDA — common in startups, vendors, and file-sharing workflows
- Confidentiality agreement — common in employment and some government contexts
- Confidential disclosure agreement (CDA) — common in life sciences
What to compare instead of the title
Is it one-way or mutual? What is excluded (public info, independently developed info)? How long does the duty last? Are there extra restraints (non-solicit, non-compete) that may be unenforceable where you operate?
SendbyLaw’s naming
We say NDA in the product because that is how senders search and think. The generated document is still a confidentiality contract. You may upload a document your counsel titled “Confidentiality Agreement.”
