HIY Decentral social network

Social media has been leading you on long enough.

Encrypted messages and group chats. Posts that travel exactly as far as you let them. A key in the chip that belongs to you. Seven days, then the post is gone. Ad-free, decentralised, built in Switzerland.

No algorithm engineered to make you angry. No corporate server reading along. No number telling you what you're worth. Just your phone, your people — and a chip that guards your identity better than any password could.

We're not here to keep you. We're here to stay.

THIS FAR YOUR POST TRAVELS — AND NOT A METRE FURTHER
Every post carries a reach budget. Each device that passes it on spends one step. Budget empty, post fades out. Friends make the trip cheaper. No likes, no boosts, no ranking — just physics. And the maths happens on your phone. Nothing reported, nothing counted.

YOUR KEY SITS IN A VAULT, NOT IN RAM
Android StrongBox builds your signing key straight into the chip. It never leaves. Every post carries that signature: forgery-proof, no central database, no password to remember. Even a rooted phone can't reach it.

ENCRYPTED — AND HONEST ABOUT IT
Posts to friends, group chats and every direct message are end-to-end encrypted (X25519 + AES-256-GCM). We can't read them. Posts to "Everyone" are public — we'd rather tell you upfront than afterwards.

WHAT'S ON THE SAME WI-FI STAYS ON THE SAME WI-FI
Pick "Local" and your post never leaves the network. Device to device, no detour through anyone's server. Photos are recompressed first — GPS and camera EXIF are gone.

AI PROTECTION THAT NEVER LEAVES YOUR PHONE
A model ships inside the app and checks every photo for nudity and violence before it goes out. Plus an estimate of whether a text reads as machine-written — shown as a hint, not a verdict. No cloud looking over your shoulder.

ONE COMMENT. SHORT AND MEANT.
No more 400-line rants. One comment per post, 2 to 60 characters. If you've got something to say, make it land.

SEVEN DAYS, THEN THAT'S THAT
Posts disappear on their own. No archive catching up with you ten years later.

WHAT ELSE YOU GET
• Chronological feed. No ads, no recommendations, no reshuffling
• Friends, Local, Everyone or Just me — you decide per post
• Group chats and direct messages with images and emoji, end-to-end encrypted
• Relevance lenses: you filter the "Everyone" feed yourself, no central ranking
• Reporting instead of silent deletion — hidden content tells you it was there
• German, English, French, Italian, Spanish

HIY+ (optional)
Larger resonance reach, three comments per post. Optional, never a requirement. The basics stay free and ad-free. Forever.

NO "JUST TRUST US"
The cryptography is out in the open at hiy.ch — excerpts from the actual source, original comments intact. Including the holes we found ourselves. Not many people show those.
