Starting off, Android users better beware, because your private data's being leaked. Sonic the Hedgehog Classic (the recent remake of Sonic the Hedgehog 1 for smartphones), Sonic Dash, and Sonic Dash 2: Sonic Boom all leak sensitive data to advertisers, including your current location, contacts, text messages, and browser history. Not only will advertisers get their hands on this data, but anyone hacking your phone can access this data, as well, due to the weak encryption present in the data-transferring library. To prevent anymore data leakage, you can either perform a full system scan with Norton Security and Antivirus, or simply uninstall the app(s) in Settings.
