A computer implemented method for constructing a hierarchical set of decryption keys for facilitating privacy-centric data storage with diverse accessibility, comprising:receiving from a user information associated with a root key;

employing a processor creating a set of cryptographic decryption keys derived from the root key, each decryption key included in the set of cryptographic decryption keys conforms to a hierarchy describing or defining encrypted data associated with the user; and

configuring decryption capabilities for a decryption key included in the set of cryptographic decryption keys based upon a location or assignment of the decryption key within the hierarchy.
