# Support for App Tracking Transparency
2+
3+
The Standalone Builder now includes a checkbox that adds support for App Tracking Transparency.
4+
This is a requirement if your app collects user data that is shared among apps or websites.
5+
Moreover, a text field is added, where you can provide the usage description string, i.e. the dialog
6+
text that will be presented to the user letting them know that their data will be shared.
