Data is stored in the blockchain forever and can be retrieved using a transaction hash as an identifier. Datacoin is a platform that can be used by applications such as torrent trackers, encrypted messaging services, and can be used to store other kinds of small data - all censorship-free.
Developers can store torrent files, certificates, and with future development, HTML pages and other kinds of meta-information in the Datacoin blockchain.
