>the author claims he did responsible disclosure and got no response

that's an easily verifiable lie. the author says the developer is not interested in fixing it just 3 comments above this one. why are you lying?

reporting this to Apple doesn't make sense either. Apple doesn't develop this app. Christian Monfiston develops this app.

Are you really going to be pedantic now and accuse me of deception? OP said: "Developer doesn't seem keen on changing things." Which I can rightly interpret as the developer didn't respond meaningfully or at all. Knowing the nature of OP, he would have surely published the developer's responses if he did. And if he did respond, what I said is semantically valid in that OP did not receive the response he or we would expect: the developer actually doing something about these vulnerabilities.

Apple absolutely should be contacted here: they have App Store Review Guidelines that this app clearly violates. Apps in the kids category and apps intended for kids cannot include third-party advertising or analytics software and may not transmit data to third parties. This app is transmitting children's location data to third parties through unsecured APIs, which directly violates Apple's kids category guidelines.

But you're completely ignoring the main point: by publishing this detailed technical writeup instead of escalating to Apple, the author has now made these children MORE vulnerable.
