The plugin does not require a Nevrivo account and does not send analytics or telemetry to Nevrivo.

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.
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.

Privacy

Site owners remain responsible for the privacy configuration of any analytics, tag manager, WhatsApp, Telegram, or other third-party service they use.

FAQ
-
Does the plugin load external JavaScript, fonts, or audio files?
-
No. Front-end CSS, JavaScript, icons, and the micro-sound generator are included locally. Sounds are generated in the browser and are disabled by default.
-
Does Nevrivo Contact Hub Lite track visitors?
-
No. The plugin does not send telemetry or analytics data to Nevrivo. It dispatches local browser events when configured contact buttons are clicked. If your site already has a
dataLayerarray, the same event can be mirrored there; the plugin does not create or load a tag manager. -
Does Lite stop working after a trial period?
-
No. Lite is a permanently free plugin. There is no time limit, usage quota, or feature lock that is removed by payment.
-
Can I use WhatsApp and Telegram together?
-
Yes. Each channel has its own enable switch, link settings, colors, size, position, and device visibility controls.
-
Can I disable sounds?
-
Yes. Sounds are disabled by default. You can enable them globally and control channel sounds and volume from the Sounds tab.
-
What happens if Pro is installed?
-
If Nevrivo Contact Hub Pro is active, Lite does not render duplicate front-end controls.
