+# dotnet-scaffold telemetry
+
+The `dotnet-scaffold` command includes a telemetry feature that collects usage data. This feature helps the `dotnet-scaffold` team understand how the tool is used so it can be improved.
+
+## How to opt out
+
+The `dotnet-scaffold` telemetry feature is enabled by default. To opt out of the telemetry feature, set the `DOTNET_SCAFFOLD_TELEMETRY_OPTOUT` environment variable to `1` or `true`.
+
+## Disclosure
+
+When you run the `dotnet-scaffold` tool the first time, it displays output similar to the following example. The text may vary slightly depending on the version of the tool you're running. This "first run" experience is how Microsoft notifies you about data collection.
+
+```console
+dotnet-scaffold collects usage data in order to help us improve your experience. The data is collected by Microsoft and shared with the community. You can opt-out of telemetry by setting the DOTNET_SCAFFOLD_TELEMETRY_OPTOUT environment variable to '1' or 'true' using your favorite shell.

+
+To suppress the "first run" experience text, set the `DOTNET_SCAFFOLD_SKIP_FIRST_TIME_EXPERIENCE` environment variable to `1` or `true`.
+
+## Data points
+
+The telemetry feature doesn't collect:
+
+* Personal data, such as usernames, email addresses, or URLs.
+* Any project data.
+
+The data is sent securely to Microsoft servers and held under restricted access.
+
+Protecting your privacy is important to us. If you suspect the telemetry feature is collecting sensitive data or the data is being insecurely or inappropriately handled, take one of the following actions:
+
+* File an issue in the [dotnet/scaffolding](https://github.com/dotnet/scaffolding/issues) repository.
+* Send an email to [[email protected]](mailto:[email protected]) for investigation.
+
