+
+# Syncfusion<sup>&reg;</sup> Telemetry 
+
+Syncfusion<sup>&reg;</sup> Telemetry library collects **anonymous usage data** to improve product quality and user experience. This data helps us better understand product usage, feature adoption, usage trends, and make informed decisions about future product planning. 
+
+Telemetry is **enabled by default**. However, you can disable it at any time if required. 
+
+N> Telemetry is automatically disabled in production environments. No data is collected from deployed applications or end users.
+
+## Why do we collect anonymous telemetry? 
+
+We collect anonymous telemetry data to: 
+
+* Understand feature adoption and usage trends 
+* Identify frequently used components and frameworks 
+* Prioritize future product planning and investments.
+* Detect compatibility trends across:  
+    * .NET versions 
+    * Operating systems 
+    * Development environments 
+
+## What data is collected? 
+
+Syncfusion<sup>&reg;</sup> collects only a limited set of anonymous usage data during development to understand product usage and improve product planning.  The following anonymous data is collected **only in development mode:** 
+
+The following data fields are collected by the Syncfusion<sup>&reg;</sup> Telemetry Library:

+
+## Where Does Telemetry Apply? 
+
+Telemetry applies only to the use of Syncfusion<sup>&reg;</sup> products during development. 
+
+* It is limited to **developer environments** 
+* It focuses on **product and feature usage**
+* It does **not apply to production applications** 
+* It does **not collect any data from end users** 
+
+Telemetry is designed solely to help improve the development experience and product quality, without impacting productions applications or users. 
+
+## Telemetry in Development Mode Only 
+
+Telemetry is designed to run only in development environments. 
+* Enabled by default during development 
+* Automatically disabled in production builds 
+* No data is collected from deployed applications 
+This ensures that telemetry does not affect your application users or production systems
+
+## How to Disable Telemetry (Opt-out)? 
+
+You can disable telemetry in Syncfusion<sup>&reg;</sup> .NET products by calling the `Telemetry.Disable()` API before using any Syncfusion<sup>&reg;</sup> product APIs in your application. 
+
+### Step 1: Add the telemetry namespace 
+
+Add the following namespace in the file where your application starts using Syncfusion<sup>&reg;</sup> components or libraries: 
+
+{% tabs %} 
+
+{% highlight c# tabtitle="C#" %}
+using Syncfusion.Telemetry;
+{% endhighlight %}
+
+{% endtabs %}
+
+
+### Step 2: Disable telemetry at application startup
+
+Call the `Telemetry.Disable()` method before initializing or using any Syncfusion<sup>&reg;</sup> product APIs. 
+
+{% tabs %} 
+
+{% highlight c# tabtitle="C#" %}
+using Syncfusion.Telemetry; 
+
+// Disable Syncfusion telemetry data collection. 
+Telemetry.Disable();  
+// Your Syncfusion product code follows here after disabling the telemetry.
+{% endhighlight %}
+
+{% endtabs %}
+
+Now, the telemetry is disabled, you can continue using Syncfusion<sup>&reg;</sup> .NET products based on your application requirements. The Syncfusion<sup>&reg;</sup> product will work normally, but telemetry data will not be collected or sent. 
+
+N> The `Telemetry.Disable()` API should be called, before creating or using any Syncfusion<sup>&reg;</sup> components, or document-processing library objects.
