Optional Pro add-on

Nevrivo Contact Hub Pro is a separate add-on distributed outside WordPress.org. Lite does not contain locked Pro functionality and does not stop working after a trial or quota. A dedicated Pro tab in the Lite settings screen presents the optional Pro capabilities using local product-page artwork and interactions; no Pro-only runtime feature code is bundled in Lite.

Third-Party Services

Nevrivo Contact Hub Lite can create user-configured links to third-party messaging services. The plugin does not automatically contact these services on page load.

WhatsApp

When a visitor clicks a configured WhatsApp button, the browser opens a wa.me URL containing the destination phone number and, when configured, the pre-filled message. That information is then handled by WhatsApp.

Telegram

When a visitor clicks a configured Telegram button, the browser opens a t.me URL containing the configured Telegram username. That information is then handled by Telegram.
