-To supplement your Session Replay data, enable [Heatmaps](/docs/session-replay/heatmaps) data collection. The current Heatmap functions as a click map, tracking user interactions with individual site elements.
+The `record_heatmap_data` option (Web only; not available on mobile) enables three types of interaction tracking during replay sessions:
 
-Enable Heatmap data collection by setting `record_heatmap_data` to `true` during library initialization.
+1. **Click events** - Captures user clicks to populate click heatmaps
+2. **Rage clicks** - Captures multiple rapid clicks on the same element (`$mp_rage_click`)
+3. **Dead clicks** - Captures clicks on unresponsive elements (`$mp_dead_click`)
 
-Ensure Session Replay is enabled, as Heatmaps only collect data during sessions with recorded replays. If a page has limited replay coverage, the resulting Heatmap may provide limited or less meaningful insights.
+These events are only captured when a session recording is in progress, and they are exempt from your plan data allowance.
 
-Clicks recorded using `record_heatmap_data` will only capture clicks while an a session recording is in progress. These clicks are sent as `$mp_click` and will not be counted against your plan data allowance.
+**Important:** Session Replay must be enabled for `record_heatmap_data` to work. Heatmaps only collect data during sessions with recorded replays. If a page has limited replay coverage, the resulting Heatmap may provide limited or less meaningful insights.
 
 **Example Usage**
 
 ```javascript Javascript
 mixpanel.init('YOUR_PROJECT_TOKEN', {
   record_sessions_percent: 1, // Session Replay must be enabled for Heatmap
-  record_heatmap_data: true   // Enable Heatmap data collection
+  record_heatmap_data: true   // Enable Heatmap, Rage Click, and Dead Click collection
 });
 ```
 
-If you use [Autocapture](/docs/tracking-methods/autocapture) to track clicks, you can leverage these clicks to populate the Heatmaps without setting the `record_heatmap_data` option during library initialization.
+<Callout type="info">
+  Events generated by `record_heatmap_data` (clicks, rage clicks, dead clicks) are exempt from your plan data allowance.

-Clicks captured by Autocapture are billable events that are counted against your plan data allowance.
