Is my AI built app secure? What to check before you launch

Your AI built app works. You have clicked through it. It looks good. But "works" and "safe" are not the same question. Working means the features do what you asked. Safe means someone who is not you cannot do things you never intended.

Why a working demo proves little

A demo shows the happy path with the right user. Security failures live in the other paths: the wrong user, a stale link, a missing check. AI coding tools aim for "does it work", so the unexamined parts, like access rules and where keys are stored, rarely get a second look.

You do not need to be a security engineer to ask the right questions. Tomi has been a software engineer for more than five years and says he is still learning the security side. That is normal. The point is to check before launch, not to be perfect.

Five questions to ask before launch

1. Can one user see another user's data? Make two test accounts. Can account B open anything that belongs to account A? Does a logged out visitor see anything private?
2. Does login do what it should? Test sign up, sign in, sign out, password reset and what happens after repeated bad attempts.
3. Are secrets in the wrong place? API keys, passwords and tokens should not sit in the app, the public code, or anything a visitor can download.
4. Are your dependencies current? AI tools pull in many packages. Old or unneeded ones add risk.
5. What data do you collect, and is it explained? Apple's guideline 5.1 expects a privacy policy that says what you collect, how, and what you use it for, plus how people can request deletion. Apps that create accounts must offer account deletion in the app.

Do the review with permission and a scope

Only test systems you own or are authorized to test. Before any deeper review, write down the scope: which app, which environment, which accounts, what is off limits. Use a test environment with test data, not your real customers.

Then follow a simple loop:

1. Run the checks.
2. List confirmed issues, ranked by how much damage they could do.
3. Fix the ones that matter most first.
4. Retest each fix.
5. Keep a record of what is still open.

When to bring in help

Get a person involved before launch if the app handles payments, health or financial information, children's data, or anything regulated. Apple also says apps in regulated fields like banking, crypto, healthcare and gambling must be submitted by the legal entity providing the service. We are not lawyers, so talk to one about legal obligations.

How we do it at SupaKid Studios

Tomi splits testing into two parts. The first is checking that all features work, see how to QA test an AI built app. The second is security testing.

Many vibe coders are not strong on cyber security, and the standard chat models can refuse security prompts. So Tomi sets up a dedicated security model connected to an agent. It acts as a security engineer for your app. You point it at an application you are authorized to test, ask it to look for weaknesses, and have it propose fixes. A human then reviews the findings, and confirmed issues are fixed and retested.

We treat it the same way we treat QA: scope first, evidence for every finding, fix, retest. The client approves what goes out. Our team is part of the iOS app team service.

What a good finding looks like

A useful security finding is specific. It says what is affected, how to reproduce it in your test environment, how bad it could be, and what to change. "The app seems insecure" is not a finding. "Account B can open Account A's saved items by changing the ID in the request, in the test environment" is one.

Rank findings by impact. Anything that exposes other people's data goes to the top. Cosmetic or theoretical issues go to the bottom. Fix, retest, and write down the result, so the next person to touch the app knows what was checked and when.

Security does not stop at launch

Your app passed a review. Then you shipped another update. New features, permissions, configuration changes and packages can all bring in new risk. Ongoing maintenance means agreed check-ins, checks after relevant changes, and a review of dependencies and access. Keep a clear list of known risks, so nothing sits unowned.

Ask yourself: who checks this app after the next update? If the answer is nobody, that is the gap.

A quick pre-launch pass

1. Two account test for data access.
2. Logged out test for private pages.
3. Search your project for keys and passwords.
4. List every package and update the old ones.
5. Read your privacy policy and compare it with what the app does.
6. Add account deletion if users can sign up.
7. Write down who owns checks after each update.
