Why do I need to login using Google? Will my password be saved?You need to register your phone to enable a secure data sending between your phone and our server. Your password will not be saved, since the login/registration is performed by Google.
What personal data are saved?We are saving just your email, your first name and your phone IMEI (the phone identifier) for identification purposes.
Is MPower a free app? Are you thinking to sell it in the future?MPower is a university project lead by the NECSTLab@POLIMI. For this reason it is a free app.
Is MPower available also for iOS, BlackBarry or Windows Phone?Nope. MPower started as (and still is) a university project. Android is the only choice if you are looking for an open source system that enable you to make all the experiments you need. Moreover, the other OS doesn't allow us to have all the intruments we neee like, for instance, backgound execution of processes. An expection could be iOS7 (see the next FAQ).
Are you planning to port MPower on other platform in the future?We are thining to port MPower on iOS7. We are reasoning about the technical issues we have to face.
What data are collected?We are collecting data about your phone internal status. We'll NEVER collect any personal data, browser history, gps positions, cookies, or any other sort of tracking data.
The application is asking for a lot of permissions, why?We need a lot of permissions to read your phone internal status, but we are not modifying any behavior without your consent.
Where are my data stored?Daily data are stored on your SD card and are then compressed and encrypted before the sending, thous ensuring the security of the overall system.
Do I need to send data manually?It is not necessary, the app daily sends all stored data automatically, if a data connection is available.
What is the purpose of the button "Send data now"?You can click on the send data now button if you want to force a data sending immediately. This was done mainly for debug purposes and will probably be changed on later versions.
When are the data sent?Data are sent daily, whenever it is available a wifi connection.
I rarely connect to wifi, will my data get lost?No at all, after 2 days without a wifi connection available, data are sent over the mobile network (2G/3G). If you don't want to use your mobile connection, you can disable this feature through the application preferences.
I have pressed the "Send data now" button, but a message said "No data to send", why?It is only possible to send data related to previous days, not about the current day. If the message "No data to send" appears, it means that the phone has automatically sent your previous data.
Are my data encrypted before they are sent?Yes, they are encrypted using an asymmetrical cryptographic algorithm to ensure that no data was being manipulated.
What type of suggestions can MPower propose?MPower issues a notification if wifi, or bluetooth or GPS is enabled but not in use.
Can I disable suggestions?Yes, in the application preferences it is possible to disable each type of suggestion separately.
Can I change the delay before a notification is shown?Sure, just enter the application preferences and change the delay time for each type of notification.
Are my data visible on this webiste?On the older version of MPower it was. Right now, with the new version we preffered to focus on the mobile app. We are planning to provide you a web view of your data in the future.
