Users from 4chan claim to have discovered an exposed database hosted on Google’s mobile app development platform, Firebase, belonging to the newly popular women’s dating safety app Tea. Users say they are rifling through peoples’ personal data and selfies uploaded to the app, and then posting that data online, according to screenshots, 4chan posts, and code reviewed by 404 Media.
This is something I worry about all the time as well, especially since I’ve started to learn how to code and experienced how easy it is to mess up and send a list with all registered users to everyone opening a page. (This was in a test environment.)
As a user, there is no proper way I know of to verify an app’s security. Most apps are closed source, but even if you could view the code, what would you look for?
Both Apple and Google have a verification process for apps that are published in their app stores, but if these worked, we wouldn’t see this happening.
There are academic researchers working on apps and privacy as well, but it’s not like you can ask them for a report on an app you’re thinking of installing.
I think it basically comes down to trust. Check if a developer has messed up in the past and how they dealt with that, that sort of stuff. And for dating apps there is this interesting article: https://www.privacyguides.org/articles/2025/06/24/queer-dating-apps-beware-who-you-trust/#reducing-the-risks-when-using-dating-apps
It’s a long read (haven’t fully read it myself yet) and it paints a bleak picture, but that’s the world we live in today.
You can pay for a 3rd party to penetration test your app, it’s good practice to do this before you launch an app, after any significant changes, and annually at a minimum.
There are also a growing number of companies offering continuous penetration testing - basically, automated pen tests - but these are expensive and it’s difficult to convince companies that the cost is worth it
Thanks, that’s good to know! If I do ever decide to release an app, I’ll definitely look into this.
