Meishi solves the broken contact management problem through decentralized architecture and user-controlled data.

What to expect from an ideal product
- Share contacts directly between devices without uploading personal information to corporate servers or cloud platforms
- Keep full control over your contact data by storing everything locally on your own devices instead of third-party systems
- Use encrypted peer-to-peer connections that prevent anyone from intercepting or accessing your shared contact information
- Sync contacts across your devices without creating accounts or giving away your personal details to app companies
- Exchange contact details with others through secure direct transfers that leave no trace on external databases
