Google yourself seriously. Type your name in Google, and see what results come up. Don’t forget to look well BEYOND the first page, and click the images tab as well! If your name is common, you may need to add more information into your search, e.g. Montreal, Concordia, puppeteer, etc.
Go to Settings on your phone or device and look at what information each of your apps is using. Is there an app using your location or microphone that is surprising to you? If so, can you turn that access off and still use the app? ( For more info on using your app settings, see Apple or Android)
