+# Telemetry Policy
+
+## Applicability
+
+This Telemetry Policy applies to the use of this plugin in combination with Sylius.
+
+By installing or using this plugin with Sylius, the user acknowledges that telemetry data is collected and transmitted as described in this document.
+
+---
+
+## 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
+- identifiers of installed and enabled plugins
+- runtime environment classification (production or non-production)
+
+Telemetry does not include, and is not intended to include:
+
+- personal data
+- customer data
+- order data
+- product data
+- business, transactional, or confidential information
+- authentication credentials or secrets
+
+A detailed description of the Sylius telemetry mechanism is available in the public issue:
+https://github.com/Sylius/Sylius/issues/18588
+
+---
+
+## 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.
+
+---
+
+## Licensing
+
+This plugin is distributed under the MIT license.
+
+Telemetry collection constitutes part of the technical operation of the software and does not alter, restrict, or supplement the rights granted under the license.
+
+---
+
+## Changes to this policy
+
+This Telemetry Policy may be updated to reflect changes in telemetry implementation, legal requirements, or operational practices.
+
+Updated versions of this policy will be made available in the plugin repository.
