Looking for someone to reverse engineer two vault apps I used years ago

Not to go into too much detail but four years ago my son used two vaults apps to store photos and videos of himself on his iPad that he wasn’t comfortable showing me and his father. I was wondering if anyone here could reverse engineer and analyse to test and see if the two vault apps were capable of uploading any data or user contents stored within the app itself to external servers or the app developers. I will give more info about the apps in DM’s (version, date of use etc) to those who are believe they can help us out. It would be really great if somebody could help as this has been a really stressful situation.
