With AntiSocial personal you can simply uninstall the application and the device wil stop collecting usage information.
Because your usage data is help in an anonymous fashion we can only locate your data with the IMEI of the device you are using. If you want you can send us the IMEI and we can delete and usge information permanently. (send to firstname.lastname@example.org)
However because it is anonmyous there is no way we can tie this back to you, as a user.
You may want to temporarily disable AntiSocial and not remove the apps. In this case under settings there there is a red disable button. When you want to app to start working again just go back in and enable the app again.
