Install Element, choose custom homeserver, try callchat.org, then use matrix.callchat.org as fallback.

The CallChat Android APK will be listed only when a real build exists. Until then, official Element clients are the safe route.

Registration should stay closed until backups, abuse routing, moderation, retention, and legal pages are reviewed.
Business and self-hosted
Planned Shield pricing: USD $5/month normal users, USD $55/month business up to 10 users, and USD $55/month self-hosted ZMath license.
Deployment safety
Do not deploy without backups, rollback, TLS checks, Synapse `server_name` review, and health checks.
Privacy and abuse
Support should never ask for passwords, pattern images, Matrix recovery phrases, private keys, or Shield internals.
