Do You Need an NDA Before Sharing an App Idea?

Why the pre-call NDA backfires

It signals that you think the idea is the asset. The asset is distribution, execution, and data you do not have yet. Serious studios hear dozens of ideas a month. They are not waiting for yours. An NDA also slows the only thing you need from a first call: a straight answer on scope, price, and whether they have shipped something like it. Offer the NDA when the conversation gets to their engineers reading your repo.

What an NDA does not protect

"An app that does X for Y" is not protected by copyright. Copyright attaches to the code, the design files, and the words you write. A patent, if you even have a case, takes time and money you should not spend before users exist. Someone can build a similar product from a public Product Hunt page. If a competitor can reconstruct it from the marketing site, an NDA with your agency was never the moat.

The clauses that matter more

Put these in the build contract, in writing, before kickoff. They protect the thing you will actually own.

• The GitHub repo is yours from the first commit, not transferred at the final invoice.
• IP assignment on payment, including designs and prompts used to generate code.
• They don't reuse your specific workflows in a product that competes with you. Reusing generic auth and billing is normal. Reusing your marketplace rules is not.
• A written list of what is in v1 and what is excluded, so "the idea" does not expand into unpaid scope.

When to send the NDA

Before a data room, before real customer data hits a prototype, before you hand over an unreleased partner agreement, and before a freelancer you have not worked with clones a private repo onto a personal account. Not before a 30-minute call. If you want that call, bring the feature list. We don't need the secret. We need the loop.
