Family.Jae – Absolute security, without logging in

At Family.Jae, your safety comes first.
Our SeedPhrase Encrypt/Decrypt software leaves no room for risk: it only starts if no external connection is active. Before opening the application, the user must disable all Internet, Wi-Fi, Bluetooth or network connections.

- As long as a connection exists, the software refuses to start, thus guaranteeing a totally isolated and inviolable environment.

- No data is recorded, no file is created, no trace is left.


- Everything is done locally, on your device, under AES-256 encryption, without ever exposing your seed phrase in plain text.

Disconnect, encrypt, be at peace.

Maximum security, guaranteed simplicity.
