Can you write a UX case study under NDA?

Most NDAs cover identifiable confidential information: the client's name, unreleased designs, internal metrics, roadmaps and commercial terms. They rarely prohibit a designer from saying they worked on a checkout, a fleet dashboard or an onboarding flow.

Read yours before assuming either way. Where it is ambiguous, ask the client: permission by email costs one message and is worth more than a guess.

Name the sector, not the company. "A European logistics operator" carries the scale and context that matter to a reader; the brand name adds recognition, not evidence.

Describe decisions instead of showing screens. The reasoning behind a change is what a reviewer is assessing, and it is rarely the confidential part.

Use relative figures instead of absolute ones. "Cut abandonment by roughly half" communicates the result without exposing revenue.

Write the process, not the artefacts. Research method, what you found, what you changed and why is a complete story with no visuals at all.

If the only numbers you have are confidential, write the case study without any. A qualitative outcome that is true beats a figure you had to blur, and inventing a plausible-sounding number is the one mistake that can cost you the role you were trying to win.

Wonfolio is built for this: it never invents a metric or a quote, and if your source material has no numbers, the case study stays honestly qualitative. Client anonymisation is a setting, not a rewrite.
