Question
Can I use confidential information after a contract ends?
My contract with a vendor has ended, can I legally use the information that I learned during the relationship now, or does confidentiality still apply?
Answer
In many cases, confidentiality does not end when the contract ends. Most NDAs and confidentiality clauses are written to continue after the relationship is over.
You may still be legally required to protect and not use certain information, even after the contract expires.
How long does confidentiality usually last?
Most agreements include a section called "Term," "Duration," or "Survival." This explains how long confidentiality continues.
Often, it lasts for a set number of years after the contract ends, such as two, three, or five years. In some cases, especially for trade secrets, confidentiality may last indefinitely or until the information becomes public through legitimate means.
Many contracts also require you to return, delete, or destroy confidential materials after the relationship ends.
When can information be used?
Whether you can use what you learned depends on:
- How confidential information is defined.
- Whether an exception applies, such as public knowledge.
- How long the confidentiality period lasts.
- Whether trade secrets are treated differently.
If the agreement does not clearly allow use, you should assume confidentiality still applies.
What to do next
- Review the contract's term and survival clauses.
- Check for return or destruction requirements.
- Identify whether the information qualifies as a trade secret.
- Confirm whether any exceptions apply before using the information.
What to consider in your specific situation
Your ability to use information after a contract ends may depend on:
- The confidentiality term in the agreement.
- Whether the information is still confidential or public.
- Any survival or post-termination clauses.
- Return or destruction requirements.
- How critical the information is to your business.
- The risk of a dispute with the former vendor.
