I made paper letters for secure information exchange. Here’s why.

👋 Hey IH!

I tried something unusual with my project Cluddy — printing real paper invitations for secure information exchange.

Normally people just drop a host address in a messenger. But I thought: what if even that is too risky for strict privacy scenarios?

So I created a concept…
📄 A formal letter with the sender’s alias, time, host, and a QR code to get the Cluddy Client.
You can hand it over in person, drop it in a mailbox, or even send it by post.

Is this the core of Cluddy? No.
But it’s a fun way to show how far privacy can go — even outside digital channels.
