Zero trust
Nothing to trust. Nothing to breach.
There is no PawShield server. No account database, no message store, no operator holding a key. The parts that could be compromised were removed, not secured.
Identity
Your key is the account
A keypair is generated on-device at first launch. The private key never leaves it — there is no upload path and no recovery server.
Encryption
Sealed before it moves
Messages are signed with your key and encrypted end-to-end. Relays only ever handle ciphertext they cannot read.
Transport
Relays you choose
Signed events travel through independent community relays. Swap them at any time — no single operator gates your reach.
Attack surface
Automated attacks need a target. There isn't one.
Credential stuffing, scripted intrusion, and machine-driven scanning all aim at the same three places: an account database, a message store, and an operator holding keys. PawShield has none of them. There is no login to brute-force, no server-side inbox to exfiltrate, and no support account that can be talked into handing over your messages.
Your key is generated on your device and stays there. To read your messages, someone needs your unlocked phone — not a breach.
Five screens.
One principle.
Pack · Circles · Map · Beacon · Calls
Circles
Private encrypted group conversations. Share updates, coordinate with your community, broadcast to your network — on your terms.
Map
A radar view of your relay network. Watch which relays your events route through and monitor connectivity live — computed entirely on-device.
Beacon
Broadcast public notes and find people across the open network. Follow, react, engage — with no platform deciding what reaches you.
Calls
Peer-to-peer voice and video over WebRTC, signaled through Nostr events. Streams travel directly between participants — never through us.
Safety tools
Block contacts and report spam directly in-app. No ads, no behavioral tracking, no advertising identifiers — not now, not later.
Watch your
own network.

The Map is a radar view of the relays your events actually travel through. It is drawn from your own connections, on your own device — nothing about your network is reported back to us, because there is nowhere to report it to.
