ALL SIGNALS
DECAY.
SIREN is a live, local network built around signals from real people in real places. No permanent feed. No algorithmic timeline. What matters survives because people nearby keep it alive.

How it works
SIGNALS GROW WITH ATTENTION.
IGNORED, THEY DISAPPEAR.
Every signal begins nearby. Engagement expands its reach; silence pulls it back toward zero.
STABLE
Alive. Local. Holding its ground.
AMPLIFIED
People are engaging. The signal travels farther.
DECAYING
Attention is fading. Reach contracts.
DEAD
No archive. No zombie content. Gone.
Keep it alive
REACT. STACK. CLONE.
Stack
Add your perspective on top of an existing signal and build context around what is happening.
Clone
Take the idea, remake it from your point of view, and send a new signal into the network.
Keys
ACCESS IS GIVEN.
NOT ASSUMED.
Keys control private access inside SIREN.
Hold someone’s key and you can tune into their Stream. For Solo, access runs both ways: each person must hold the other’s key.
Issue one. Request one. Revoke one. Anytime.

Go private
PUBLIC SIGNALS REACH PEOPLE NEARBY.
THESE DON’T.
Three private modes. Different intimacy, different scale, same rule: access is deliberate.
SOLO
Just the two of you.
Private, reciprocal communication between two people who hold each other’s keys.
CIRCLE
Your inner group.
A smaller trusted space for people you intentionally pull closer.
STREAM
Broadcast to your keyholders.
A private channel for everyone you have deliberately granted access to.

SIREN is testing with a small group on iOS and Android before wider release. Leave your email and we’ll reach out as access opens.
