NullLink
NullLink is a privacy-first communication platform built on a zero-knowledge architecture. Whether peer-to-peer or relayed, all data is end-to-end encrypted and never intercepted. Features include encrypted chat, HD video and voice calls, file sharing, collaborative whiteboard, screen sharing, and dual camera — all installable as a PWA. Messages exist only in memory; close the tab and they're gone.
The problem
Mainstream messaging apps collect metadata, store messages on servers, and monetise your communication patterns. Even 'encrypted' platforms often retain metadata, device fingerprints, and social graphs. Privacy-conscious users and teams have no option that is architecturally incapable of spying on them.
