This specific element serves to define the rules – or the object / consideration – of the contract, without disclosing the exact information. For example, an NDA for an exclusive designer clothing store might contain a statement like this: “Confidential information includes customer lists and purchase history, credit and financial information, innovative processes, inventory, and sales.” A confidentiality agreement (NDA), sometimes referred to as a confidentiality agreement, is a written contract between two parties (persons or entities) that prohibits the exchange of confidential information disclosed to them. In short, if you are asked to sign an NDA, you promise to keep secret all sensitive information that is shared with you and not to share it with others. If you are the NDA exhibitor, ask someone else not to share information that you can share with them.
