I also want to point out that a lot of these games purposefully misclassify themselves in the AppStore. Meaning if you are a parent and you say “I want my kid to have 1-2 hours of game time, but all research tools are allowed all the time” Some games will report themselves as “Information and Reading” to get around settings. I find oftentimes the more garbagey the game the more likely it will do that.
Best place to start if you’re taking security seriously; Implementing file encryption for example has to start with “I would rather that I myself potentially lose access to this data than for it to possibly fall into another person’s hands.”
