One of the questions founders ask us most often, usually quietly, is some version of "is my users' data safe, and how would I even know?" It is a fair question, and you should not feel behind for asking it. AI tools are very good at making an app that works. They are not careful, by default, about who can see what.
Here are the problems we find most often in AI-built apps, and how you can check for several of them without being a developer.
Can users see each other's data?
This is the big one. In a lot of vibe-coded apps, the app asks the database for "all the orders" and then shows you yours, trusting the screen to hide everyone else's. The data is all being sent to the browser. Anyone a little curious can see it.
How to check: open your app, log in as a test user, and look at the web address and the browser's developer tools (right-click, then Inspect, then the Network tab). If you can change a number in the URL, like an order or profile ID, and see someone else's information, that is a serious leak. If you are not sure how to test this, it is worth having someone check it for you specifically.
Are your keys and secrets exposed?
Apps connect to other services (payments, email, AI) using secret keys. Those keys are supposed to live on the server, never in the browser. AI tools sometimes put them where the browser can read them.
How to check: in your browser, right-click your app and choose "View page source", then use Find (Ctrl or Cmd + F) to search for words like key, secret, token, and sk_. If you see long random-looking strings next to those words, they may be exposed. Anyone can read that page.
Is there real login protection?
A login screen is not the same as real access control. The question is whether the server actually checks who you are on every request, or whether the app just hides buttons it hopes you will not find.
How to check: this one is harder to test yourself, but a simple smell test is whether you can reach a page you should not by typing its address directly while logged out or logged in as the wrong user. If a page you expected to be private loads anyway, the protection is not real.
Is your database open to the internet?
Some setups leave the database reachable from anywhere, protected only by a password that may be sitting in the app's code. That is a door waiting to be tried.
How to check: this generally needs a developer to verify, because it depends on how your hosting is configured. It is one of the first things we look at in an audit.
What to do with what you find
If any of these checks turned something up, do not panic and do not try to patch it blindly, because a half-fix can give you false confidence. Write down what you saw and get someone to look at the whole picture. Security problems usually travel in groups: if one of these is wrong, others often are too.
A security-focused audit answers the question you started with. We check who can see what, whether your keys and data are exposed, and whether your login actually protects anything, then we tell you in plain language what is at risk and fix it.
We spent 15 years building software where a data leak was not an option, so this is the first thing we look at, not the last. If you want a straight answer on whether your users' data is safe, that is where making your app production-ready starts.
Want a straight answer on your own app?
We start with an honest audit: what is solid, what is fragile, and what it takes to get to production. You get it in writing, in plain English.
