A non-disclosure agreement, or NDA, is a binding contract that defines what information is confidential and prohibits you from sharing it outside the agreement. For freelancers, signing an NDA is routine — especially when you will access proprietary data, unreleased products, or business strategies.
How it works
When you sign an NDA, you agree not to disclose, share, or use the client’s confidential information for any purpose outside the project. A standard NDA includes these elements:
| Element | What it defines |
|---|---|
| Parties | Who is bound (you and the client) |
| Confidential information | What is protected (trade secrets, plans, customer data) |
| Exclusions | What is not covered (public info, things you already knew) |
| Obligations | What you must and must not do |
| Duration | How long the obligation lasts (typically 1 to 5 years) |
| Remedies | What happens if someone breaches it |
There are two types:
- Unilateral (one-way): The client shares confidential information, and only you are bound. This is the most common type in freelance work.
- Mutual (two-way): Both parties protect each other’s information. Appropriate when you are sharing proprietary methods or tools with the client.
Most freelance NDAs are unilateral. The client sends their template, you review and sign before any confidential information is shared — often before a discovery call.
Why it matters for freelancers
NDAs are so common that many freelancers sign them without reading. That is a mistake. Most are reasonable, but some contain clauses that can seriously restrict your business.
A well-written NDA costs you nothing. It means you do not talk about proprietary information publicly. A poorly written one can prevent you from working with competitors (a non-compete disguised as an NDA), claim ownership of your pre-existing knowledge, or define “confidential information” so broadly it covers general skills and industry techniques.
The difference between standard and restrictive usually comes down to two things: how broadly “confidential information” is defined and whether a non-compete clause is hidden in the agreement.
If you share proprietary processes or frameworks with clients, a mutual NDA protects your methods from being passed to competitors. For more on contract protections, see our freelance contract essentials guide.
Example
A fintech startup hires you to redesign their mobile app. Before sharing their product roadmap and user analytics, they send a unilateral NDA. You review it:
- Confidential information: product plans, user data, financial projections, technical architecture
- Exclusions: publicly available info, things you knew before the engagement
- Duration: 3 years
- No non-compete clause — you can work with other fintech companies
This is clean and standard. You sign, receive the brief, and proceed. You can mention you “redesigned a fintech mobile app” in your portfolio, but you cannot share the roadmap, internal metrics, or unannounced features.
Common mistakes
Signing without reading. Every NDA is different. Take 15 minutes to read it. Pay attention to the definition of confidential information, duration, and any non-compete language.
Not catching a hidden non-compete. Some NDAs include clauses like “Contractor agrees not to perform similar services for any competitor for 12 months.” That is a non-compete, not non-disclosure. It can block you from working in your own industry.
Agreeing to an overly broad definition. If “confidential information” means “anything disclosed during the engagement,” that could cover general skills and industry knowledge. Insist on a specific, bounded definition.
Forgetting about portfolio rights. An NDA does not automatically prevent you from showing work (that is an IP/work-for-hire issue), but some are drafted broadly enough to cover it. Negotiate a portfolio carve-out if showcasing the work matters.
FAQ
Should I sign an NDA before a discovery call?
Yes, if the terms are reasonable. Clients often need to share sensitive details during discovery to get an accurate proposal, and an NDA gives them confidence to be transparent. Just make sure it is standard and does not contain hidden non-compete restrictions.
What happens if I accidentally breach an NDA?
It depends on severity. Minor, unintentional disclosures can often be resolved with prompt notification. Serious breaches — sharing trade secrets, leaking product details — can result in lawsuits and significant damages. If you think you may have breached an NDA, consult a lawyer immediately.
Can I ask a client to sign a mutual NDA?
Yes. If you are sharing proprietary methodologies, templates, or business information, a mutual NDA protects both sides. Most clients agree without pushback when you frame it as protecting everyone’s information equally. Include this alongside your scope of work agreement.
