PayPal and license request routes are available. Access is activated after payment confirmation.

Element-compatible accounts can use homeserver callchat.org. New accounts use access review to reduce spam and protect the network.
ZMath boundary
Public pages describe behaviour and licensing only. Private ZMath implementation details are not published.
Self-hosting
Self-hosted licensing covers use of the premium layer, not republication of premium source.
Simple rule
Free messaging first. Premium Shield only when it adds value.
Users can start with normal secure Matrix chat, then add ZMath Shield for files, vaults, and policy-controlled premium workflows.
