Is Litentry on Polkadot?

Could you please clarify if Litentry is indeed a project that is currently operating on the Polkadot blockchain? I'm particularly interested in understanding if Litentry utilizes Polkadot's unique architecture and interoperability features to achieve its goals. Additionally, are there any plans for Litentry to expand its functionality or integrate with other blockchains within the Polkadot ecosystem in the future? Your insights would be greatly appreciated.
