+## Mandatory telemetry
+
+Telemetry data collection is mandatory when this plugin is used.
+
+While this plugin is installed and active, Sylius telemetry operates under the conditions defined by this plugin and cannot be disabled independently.
+Telemetry behavior outside of this scope follows the standard Sylius configuration.

+## Scope of collected data
+
+Telemetry is limited to non-identifying technical data, which may include:
+
+- Sylius version
+- plugin version
+- PHP version and selected dependency versions

+
+Telemetry does not include, and is not intended to include:

+## Purpose and use of telemetry data
+
+Telemetry data is collected for the purpose of:
+
+- understanding usage patterns within the Sylius ecosystem
+- analyzing the adoption and frequency of plugin usage
+- identifying commonly used versions of Sylius and plugins
+- supporting maintenance, compatibility, and future development efforts
+
+Telemetry data is processed in aggregated form and is not used to identify individual users, installations, or businesses.
