Meishi – Privacy-first contacts app with automatic P2P sync and E2EE

Summary: Meishi addresses outdated contact data and privacy risks by enabling users to create digital profiles that automatically update across authorized contacts via peer-to-peer synchronization with end-to-end encryption. It eliminates centralized storage of private data and grants users full control over their information.

What it does

Meishi creates digital contact profiles that sync updates automatically to authorized contacts using Signal Protocol for encrypted peer-to-peer communication. Private data is never stored on centralized servers, with a client-server model used only for public search.

Who it's for

It is designed for users needing up-to-date contact information and strong privacy controls, particularly in B2B environments where contact data quickly becomes obsolete.

Why it matters

Meishi prevents stale contact data and protects user information from breaches by removing reliance on centralized databases vulnerable to attacks and misuse.
