Systems and methods are included for creating an assured record of a user interaction. An application on a user device can receive an agreement. The agreement can include a specification with instructions for assuring the user interaction. The application can pass the agreement to an assured module installed in the application. The assured module can present the agreement to a user in an interface. The assured module can receive user input indicating acceptance or rejection of the agreement. The assured module can generate a confirmation file that confirms the user interaction. The assured module can sign the confirmation file with a digital signature that can be used by other entities to verify the authenticity of the confirmation file.
