SpotLink — 오프라인 메신저

SpotLink is an offline messenger that operates without the internet, carrier networks, or servers. It connects directly with nearby devices via Bluetooth to exchange messages, photos, and files.

■ No Internet Required

You can chat with nearby friends even in disaster situations where communication networks are down, in places where international roaming is unavailable, in areas with weak signals like underground stations, mountains, or the sea, or at festivals and stadiums where data is unavailable due to crowds.

■ Reaching Far Away (Multi-hop Mesh)

Even if you are too far apart to touch directly, messages are automatically relayed if there is another SpotLink device in between. The more people there are, the further the message reaches.

■ Automatically Delivered When You Meet Again, Even If You Are Not Together

If the recipient is temporarily out of range, the message is safely stored and automatically delivered the moment you meet again. You can check both the sending and receiving times.

■ Content Only the Two of You Can See (End-to-End Encryption)

All messages are end-to-end encrypted (AES-256). Even other devices acting as intermediaries can never read the content. Since there is no server, it is not stored anywhere.

■ Securely Add Friends via QR Code

Scan a friend's QR code to exchange password keys, making you authenticated friends. Users found nearby also appear automatically.

■ Save Battery Automatically

It automatically switches to power-saving mode when the connection is stable and quickly switches back to power when finding new friends.

SpotLink requires no account registration and does not ask for a phone number or email address. Your conversations exist only on your and your partner's devices.
