Does Uninstalling An App Clear Data?

First of all, when you remove an app from an Android mobile device, such as when you install and uninstall an app from playstore, part of the app data will already have been purged when you uninstall the programme. This is the case even if you just uninstalled the app from playstore. When you download an application to your device via Google Chrome or any other web browser as an apk file, you have the option to manually remove the file after installation.
