Usage Logs

[casaout]

As briefly discussed yesterday, unless you have a better idea, it might make sense to log a few key events in a separte table usage_data with the columns id, ts (or created, edited, ...), type and additionalInformation:

The idea of additionalInformation is to flexibly add extra context/data, where useful. In past studies, we sometimes added json objects that we could later easily parse.

The following event-types (for now):

• start (app start, also log timezone and app version number)
• stop (app shutdown)
• lock-screen (logout/signout/lockscreen)
• unlock-screen
• startExport
• finishExport (+ settings)
• opened + closed/answered experience sampling popup and wheter it was automated or manually opened
• anything else that makes sense?
