Features
Everything a modern team needs.
Nothing it doesn't.
Voice & video calls
Crystal-clear one-to-one calls that work reliably across home, mobile, and office networks. Native lock-screen ringing on iPhone — calls feel like calls, not notifications.
Group chats
Encrypted group messaging built for the way teams actually work. Add members, manage admin roles, leave gracefully — every message stays end-to-end encrypted.
Multi-device sync
Use the same account on your phone, tablet, and laptop. Each device has its own keys, so adding or removing a device never compromises the rest.
Reactions, replies, edits
The modern messaging features your team expects — react, reply, edit, delete-for-everyone — with the privacy guarantees you actually need. No trade-offs.
Media sharing
Share photos, voice notes, videos, and files with the same end-to-end protection as your messages. Encrypted on your device, decrypted on theirs, opaque to everyone in between.
App Lock + biometrics
Face ID, Touch ID, or fingerprint required to open the app — separate from your device unlock. So if a colleague borrows your unlocked laptop, your messages stay private.
Push notifications
Native push on iOS (APNs) and Android (FCM), plus web push for desktop. Notifications carry no message content — your device decrypts the payload locally.
Self-hostable
For organisations that need their data to stay on their own infrastructure. Designed with data residency, sovereignty, and right-to-erasure in mind from day one.

Security
The boring details, in plain English.
✓ Your messages stay yours
Every message is encrypted on your device before it leaves and only decrypted on the recipient's device. The data that travels through our servers is opaque — not just to outsiders, but to us as well.
✓ Forward secrecy
Each conversation continuously rotates its encryption keys. Old messages can't be recovered just because someone has a current key. This is the gold standard for private messaging, and we apply it everywhere.
✓ No advertising. No data mining.
We don't sell ads, we don't sell data, and our business model has nothing to do with analyzing what you say. Operational telemetry stays operational — error reports, performance metrics, nothing about message content or who you talk to.
✓ UK-incorporated, GDPR-ready
Data protection is built in, not bolted on. As a UK-incorporated company we operate under UK GDPR with clear obligations on data minimisation, transparency, and your right to erasure. Your data is treated as yours.
✓ Open security practices
We publish a security.txt contact for responsible disclosure, restrict our certificate authorities via CAA DNS records, enforce HTTPS everywhere with HSTS, and pin certificates in our mobile apps. The fundamentals, done right.
✓ Built to be trusted, not believed
Privacy claims are only as good as what they actually do. We design every feature so that the security model is the same whether you trust us or not — your data stays protected by mathematics, not policy.
FAQ
Questions we actually get asked.
Is Messenger really end-to-end encrypted?
Yes. Encryption happens on your device before any message leaves it, and decryption happens on the recipient's device after it arrives. Everything in between is opaque ciphertext. This applies to text, voice notes, calls, photos, videos, and files.
Who is this designed for?
Teams and organisations that need private, professional messaging — alternatives to consumer apps where personal and work communication get mixed together. Built for clear admin controls, organisational structure, and the option to deploy on your own infrastructure.
Can my organisation deploy this on its own infrastructure?
Yes. Self-hosting is supported and is one of the things we designed for from day one. If your organisation has data-residency or sovereignty requirements, get in touch at info@chattriix.com and we'll talk through it.
What about pricing?
Pricing will be announced alongside general availability. Pre-launch our focus is on getting the product right.
When are the iOS and Android apps available?
Coming to the App Store and Google Play. The web app at messenger.chattriix.com is available today with the same security model.
How do you handle data and privacy?
We collect the minimum data needed to operate the service. You can request deletion of your account and associated data at any time. We do not sell data, do not run advertising, and do not analyse the contents of your communications.
