If for any reason you want to withdraw from the experiment, you can easily do so by uninstalling the application. Simply follow the rules for uninstalling an android application, and uninstall the application. No further connectivity tests nor data sensing will be performed anymore. In case you withdraw from the experiment, we kindly ask you to email us (firstname.lastname@example.org) with a brief description of your experience. This will help us improve the application for future experiments.
We also give you an option to withdraw all or any portion of your data after the experiment. If you want to use this option please email us (email@example.com) your IMEI with “withdrawal” in the subject line or talk to us in person during one of the application demo sessions.
