Privacy-first applications built for a world that is watching.
THE LAB
Every application from PointBreakLab is built on the same principle — your data belongs to you.
ENCRYPTED · SERVERLESS · P2P
The messenger that cannot be surveilled. No accounts, no servers, no phone numbers. Pure peer-to-peer encryption.
SECURE NOTES · COMING SOON
End-to-end encrypted notes that live only on your device. No cloud sync, no account required.
IN DEVELOPMENT
The next tool from PointBreakLab. Privacy-first, as always.
WHISPR
Zero servers. Zero accounts. Zero phone numbers. Your messages travel directly between devices, encrypted end-to-end before they ever leave your hands.
Messages travel peer to peer. There is no company server to subpoena, no database to breach, no authority to comply with.
X3DH + Double Ratchet. The same cryptography trusted by journalists, activists, and governments worldwide.
Bluetooth LE mesh delivers messages with no internet. At a protest, on a plane, in a blackout — anywhere.
Route messages through the Tor network for anonymised delivery. Your IP is never exposed to peers.
ECIES-encrypted email between Whispr users. Threads, reply-all, forward — with full E2EE, no central server.
Your identity is a locally-generated Ed25519 key pair. No email, no phone, no registration of any kind.
HOW IT WORKS
01
Your message is encrypted on your device before it ever leaves. Only the recipient's Ed25519 key can decrypt it.
02
The app automatically picks the fastest available route — direct LAN, Tor hidden service, or BLE mesh.
03
Only your contact's device decrypts the message. Not us, not your ISP, not anyone in between.
TRANSPORT LAYER
When on the same Wi-Fi, messages travel directly — sub-second delivery, zero internet required.
Route through Tor hidden services for anonymous, censorship-resistant delivery across the internet.
Bluetooth Low Energy mesh. Send messages nearby with no Wi-Fi, no internet, no infrastructure at all.
ARCHITECTURE
Every layer of Whispr is designed assuming the network is hostile, every intermediate is compromised, and the adversary is well-funded.
WHAT'S COMING
PointBreakLab ships continuously. Here's what's in the pipeline.
WHISPR · IN PROGRESS
End-to-end encrypted peer-to-peer calls over LAN and Tor. No relay server, no recording, no third party.
WHISPR · PLANNED
Multi-party encrypted group chats using a shared group key, derived without a central key server.
KNOT · COMING SOON
Device-only encrypted notes. No sync, no cloud, no account. Ships after Whispr 1.0 stabilises.
WHISPR · PLANNED
Per-message timers. Messages evaporate from both devices after the set duration — no trace left.
GET WHISPR
Available for Android. iOS coming soon. No account. No tracking. Just install and go.
THE STUDIO
PointBreakLab is a studio building privacy-first applications. Every app ships free, with zero access to your data — by design, not by policy.
Every tool starts from the same question: what would this app look like if we genuinely had no access to your data? Whispr is the answer for communication.
