If you've wrapped a web app into something submitted to the Apple App Store or Google Play, it's easy to assume that passing app review means the security side has been checked along with everything else. Worth being precise about what app store review actually looks at, because the overlap with what this blog covers is smaller than people often assume.
What app store review is actually built to catch
App review focuses heavily on things like: does the app crash or violate basic functionality guidelines, does it use private or restricted device APIs it shouldn't, does it clearly disclose what data it collects and get proper permission for things like location or camera access, does it avoid obviously malicious behavior. This is genuinely useful, user-facing consumer protection, and it does catch a real category of bad actors and broken apps.
What it has essentially nothing to say about
App review doesn't test whether one logged-in user of your app can see another user's data. It doesn't check whether your database's access rules are configured correctly. It doesn't verify your admin panel actually requires authentication, or that your API routes check who's asking before handing back data. None of that is visible from the outside the way a reviewer testing your app's basic functionality and permissions would encounter it, and it isn't within the scope of what app store review is trying to accomplish in the first place.
Why this gap matters specifically for AI-built apps
An app can sail through app store review, functioning perfectly, correctly requesting the right device permissions, disclosing data collection accurately, while its backend has exactly the kind of missing row-level security or exposed admin route that's caused nearly every incident I've written about this year. The two things, app store compliance and actual data security, are almost entirely independent checks, and passing one tells you nothing meaningful about the other.
What's actually worth doing before submission, separate from the store's own requirements
- Run the standard checklist from this blog regardless of app store approval: cross-account data test, logged-out admin test, key search, database rule review.
- Don't treat 'approved by the app store' as any kind of signal about your backend's access control. It isn't measuring that at all.
- If your app requests sensitive device permissions, camera, location, contacts, confirm the data collected through them is actually protected on your backend with the same rigor as everything else, since app review confirms you asked correctly for permission, not that what you do with the data afterward is secure.
App store review is a real, valuable gate for a specific set of concerns. It was never designed to be, and shouldn't be treated as, a security audit of your backend. That check still has to happen separately, on its own, regardless of which store your app eventually lives in.
