Any app data stored locally on the device is connected only to the app. If the app is uninstalled, the app data disappears. Local data is not shared without your knowledge.
In some cases, you may have the option to share something with the world outside the app. It will then be clearly visible, like for example the text you share via an email, or via information and confirmation before you send something to for example a remote website. The intention is to never share something without your knowledge!
