Overlay1404 thanks. That seems to be half way to what im looking for as it allows (with an additional mitm add in) to decrpyt traffic to allow the user to manually check for sensitive data.
What was interesting about the lumen app is that it seemed to find things like the device serial number in the payload, lowering the level of expertise needed to assess an app and the data it was trying to scrape.
Does the community have any more suggestions ?
Thanks in advance
