Heivol Connect
A private messenger where web and mobile are equal first-class clients — with voice and video calling rolling out. Built on the Signal Protocol for end-to-end encrypted conversations, authenticated through Heivol Identity — no phone number required to sign up. Free for everyone with a Heivol account.
Built different
Signal Protocol encryption
Heivol Connect uses the Signal Protocol for end-to-end encrypted conversations — messages are sealed on your device, and we can't read them. Conversations bridged to other networks are encrypted in transit but decrypted at the bridge, so they aren't end-to-end; the app tells you which is which.
No phone number required
Sign in with Heivol Identity over OIDC. Your account is tied to a verified e-ID, not a phone number. No SIM swaps, no SMS verification, no metadata leaking your mobile number.
Web and mobile as equals
The web client (React) and mobile apps (React Native) share the same feature set and the same real-time delivery guarantees. Neither is a second-class citizen.
Your keys, your metadata
Encryption keys live on your devices. We minimise server-side metadata by design — we don't need to know who you talk to, when, or how often.
Rich messaging
File and media sharing, voice messages, emoji reactions, location sharing, scheduled messages, and message requests from unknown contacts — all encrypted.
Voice & video calling
1:1 and group voice and video calls, peer-to-peer where possible with a relay fallback, are rolling out across web and mobile. The same encrypted account, the same Heivol Identity login — no extra app to install.
Bot and LLM API
A stateless REST API for developers and AI agents. API-key auth, polling or webhooks, no WebSocket requirement. Build bots the same way you would on Telegram.
