How can I get tracking data (transparently) from Android, like the data from sensors that apps routinely collect?

I want to make a data science workshop. I know that some apps in smartphones in general have the ability to get tracking data, for ad, tracking and surveillance purposes. I want to make people more conscious of this, by letting the user get this data and work with it him/herself. Are there any more direct ways for accessing data of sensors in a given android phone (in a transparent, non-invasive way), export it to a file in the phone so that it is possible to be read by a script for data science purposes? Thanks in advance.
