Heivol Connect
An end-to-end encrypted messenger where web and mobile are equal first-class clients — with voice and video calling rolling out. Built on the Signal Protocol, authenticated through Heivol Identity — no phone number required to sign up. Free for everyone with a Heivol account.
Built different
Signal Protocol encryption
Not a re-skin or a marketing claim. Heivol Connect implements the Signal Protocol for all 1:1 and group conversations. Messages are encrypted end-to-end before they leave your device.
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.
