Help and advice with premium features on Android phone

Hi

I have purchased the premium anti-theft product and have figured most of it out (despite a lack of current documentation!).

When recording audio, occasionally I get a ’ could not upload due to lack of internet connection ’ following the recording, which is fair enough on a cell connection.

My question is this - are the files stored locally on the device so they can be downloaded and listed to later? and if so where would they be located?

Also. the ’ silent ’ SMS feature is disabled (currently running android 4.4) any idea why?

Many thanks in advance.
