Under The Hood
Production architecture & data flow
How requests move through our fault-tolerant microservices, geospatial caches, and realtime socket clusters.
01
Device Key Generation
Client app generates public/private keypairs locally upon registration; public keys stored in server directory.
02
Payload Encryption & Transmit
Message payload encrypted using recipient's public key; transmitted to server via high-speed WebSockets.
03
Offline Queue or Instant Push
If recipient is online, message delivered instantly; if offline, encrypted payload queued until reconnection.
04
Client Decryption & Receipts
Recipient decrypts payload locally; server receives cryptographic delivery and read receipts (double blue ticks).

Clear Answers
Frequently asked questions
Everything you need to know about code ownership, store publishing, and custom features.
Is the end-to-end encryption truly secure?
Yes. Private keys never leave user devices. Even server administrators with full database access cannot read message contents or decrypt voice calls.
Do you provide a Web version like WhatsApp Web?
Yes, a responsive web app with QR-code pairing is included for seamless desktop messaging.
What happens when a user is offline?
Encrypted messages are safely buffered on the server and delivered the instant the device re-establishes an internet connection.
Can we use this for an internal enterprise corporate messenger?
Absolutely. Many clients deploy this internally as a secure, self-hosted Slack or Teams alternative to safeguard corporate IP.
How are push notifications handled for encrypted chats?
Silent VoIP and high-priority FCM/APNs push notifications wake up the app to fetch and decrypt incoming messages locally.
