CARP Communication Sampling Package

pub package

This library contains a sampling package for communication sampling to work with the carp_mobile_sensing package. This packages supports sampling of the following Measure types:

  • dk.cachet.carp.phone_log - the phone log.
  • dk.cachet.carp.text-message-log - the text (sms) message log.
  • dk.cachet.carp.text-message - incoming text (sms) messages.
  • dk.cachet.carp.calendar - all calendar entries.

See the wiki for further documentation, particularly on available measure types and sampling schemas. Note that collection of phone and text message data is only supported on Android.

There is privacy protection of text messages and phone numbers in the default Privacy Schema.
