Data Deletion

We offer you the right to delete your data from our study. Our study records no per­son­al­ly iden­ti­fy­ing infor­ma­tion, so the only way we can do this is to delete all data that was col­lect­ed by your device.

Please fol­low these steps:

  1.  You will need to find your “Android ID”. We rec­om­mend the app “Sys­tem Info for Android”. Please install this, and then go to “Sys­tem” tab, then “OS” and write down the 16 char­ac­ter string named “Android ID”. You can delete the app afterwards.
  2.  Please email “” with a request to delete data for the device. Please include the Android ID.
  3. We expect that with­in three work­ing days we will have delet­ed the data. We will con­firm dele­tion to you via email.
  4. After we have con­firmed dele­tion, to com­ply with our data pro­tec­tion stan­dards we will delete your email request, so that we do not retain per­son­al­ly iden­ti­fy­ing infor­ma­tion for you.

Please note that while we offer the right to delete data, approx­i­mate­ly one month after the data has been col­lect­ed, sum­ma­tive reports of the data may have been made avail­able on our web page or sub­mit­ted for pub­li­ca­tion. Thus it may not be pos­si­ble to alter these sum­ma­tive reports.
