When a company takes up a project with a client they normally will have to sign an agreement with the client that neither party will disclose information that will be shared as part of the project to anybody else and that the information shared shall not be used for creating competing products/services by the company. This is a standard document that needs to be signed for most projects. This document is also referred to as Non Disclosure Agreement. We are publishing our Confidential Disclosure Agreement here. Feel free to copy and use for your needs.
