PrivacyBreacher

+ +PrivacyBreacher is an Android app built as a proof of concept for a research article describing the privacy issues in Android. This app can access following information from your phone *without requesting any permissions*: + + 1. **Screen state of your phone (i.e., when your phone screen goes off/on)** + 2. **Monitor when you plug-in and remove your phone charger and wired headphones.** + 3. **Figure out at what time you switched on/off your phone (not directly implemented) .** + 4. **Access most of your device related information like your phone model, manufacturer etc.** + 5. **Keep track of your WiFi/Mobile data usage.** + 6. **Get a list of all the apps installed on your phone.** + 7. **Construct a 3D visualization of your body movements.** + +This app supports Android Pie (Android 9, API 28) or later versions. + +## Research Article + +To get more information on how this app can access all that data, check out our article here! + +## Screenshots + + + + +## Download + +Links will be provided soon! + +## Contribute + +We accept pull requests for this app. If you find any bugs or want to add new features or just want to improve the code structure, then pull requests are most welcome! + +## License + +MIT License + +Copyright 2020 DataBurn + +Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
