NDA Explained: What a Non-Disclosure Agreement Actually Means (in Plain English)
Confused by your NDA? Learn what a Non-Disclosure Agreement covers, what you can and can't share, and the clauses you should watch for before signing.
What Is an NDA?
A Non-Disclosure Agreement (NDA) is a legal contract that prevents you from sharing certain information with others. It's one of the most common documents in business — freelancers, employees, contractors, and founders sign them regularly. But most people sign NDAs without fully understanding what they're agreeing to.
An NDA defines what counts as "confidential information," how long you must keep it secret, and what happens if you break the agreement. The consequences can range from a lawsuit to financial penalties worth tens of thousands of euros.
Types of NDAs
One-Way (Unilateral) NDA
Only one party shares confidential information. Common when a company hires a freelancer or contractor. The freelancer is bound by the NDA; the company is not.
Two-Way (Mutual) NDA
Both parties share confidential information and both are bound. Common in business partnerships, joint ventures, or when two companies explore a deal.
5 Key Clauses to Watch For
1. Definition of Confidential Information
This is the most important clause. A broad definition like "all information shared between parties" could prevent you from discussing even basic project details. Look for specific, reasonable definitions that list categories of protected information.
2. Duration
How long must you keep the information secret? Some NDAs last 1-2 years after the relationship ends. Others say "in perpetuity" — meaning forever. Perpetual NDAs are common for trade secrets but unusual for general business information.
3. Exclusions
Good NDAs specify what is NOT confidential: information that's already public, information you already knew, or information you learned independently. Without these exclusions, you could be in breach for sharing publicly available knowledge.
4. Non-Compete Clauses
Some NDAs bury a non-compete clause inside them — restricting you from working with competitors for months or years. This is different from confidentiality and can severely limit your career options. Always check for this.
5. Remedies and Penalties
What happens if you breach the NDA? Some specify a fixed penalty (liquidated damages), others allow the other party to sue for actual damages. Some include "injunctive relief" — meaning a court can order you to stop doing something immediately.
Red Flags in NDAs
- Overly broad definition of "confidential information"
- No exclusions for publicly available information
- Perpetual duration for non-trade-secret information
- Hidden non-compete or non-solicitation clauses
- Disproportionate financial penalties for breach
- One-sided obligations in what should be a mutual agreement

Frequently Asked Questions
Can I refuse to sign an NDA?
Yes, but the other party may refuse to work with you. You can negotiate specific terms — like narrowing the definition of confidential information or reducing the duration — before signing.
What happens if I accidentally break an NDA?
It depends on the contract. Some NDAs allow for a "cure period" where you can fix the breach. Others allow immediate legal action. The best protection is knowing exactly what your NDA covers before you sign it.
Is an NDA the same as a confidentiality agreement?
Yes. "Non-Disclosure Agreement" and "Confidentiality Agreement" are used interchangeably. They serve the same purpose.
