The disclosure is related to a data management platform ("platform") for providing a secure storage environment for digital contents associated with a user. The platform may be accessible via an app installed on a user device, which allows the user to upload, modify, and view digital contents. Because a digital content is mapped to a universal scaffold in a structured format, the platform can organize and display the digital contents in meaningful ways. The digital contents can be hosted on a remote server. The platform provides zero-knowledge encryption so that the digital contents stored at the server are secure, as in one cannot know the contents of the encrypted information stored at the server. The platform also facilitates zero knowledge offers in which offers are sent to multiple users but the server does not know to which users the offers are presented until an offer is accepted by the user.
