No doom scenarios, but honest: what actually happens when your customers' data ends up in the wrong hands, and how big that risk really is for a small app.
How it usually starts
With small apps it is rarely a targeted attack. Usually it is something simple: a database accidentally open to everyone, a key left in the code, or an admin page without a password.
There are programs sweeping the internet all day that do nothing but look for such open doors. They find a small app just as easily as a big one.
What happens next, concretely
- Your users' data — names, email addresses, sometimes more — has ended up with strangers.
- You have to report it: for data of EU citizens, the data protection authority requires a breach to be reported within 72 hours if there is a risk.
- You have to inform your users — never fun, but required.
- The trust you built takes a dent that an apology email cannot fix.
The costs are mostly indirect
The fine makes the news, but for a small business owner the other costs weigh heavier: figuring out what exactly happened, closing the leak, updating users, and keeping your business running in the meantime. That easily takes weeks of attention.
And if the app is your business, a breach hits your revenue directly.
With backups you can restore lost or changed data, but they cannot undo a breach.
The good news
Most breaches at small apps come from a small set of well-known mistakes: open databases, leaked keys and permissions set too broadly. Those can be found in advance with an automated check — you do not need to be an expert to prevent them, only to fix them.

Frequently asked questions
Is my small app really interesting to attackers?
Not you specifically — but the automated scanners do not discriminate. An open door is an open door, however small the house behind it.
Do I really have to report a breach?
For personal data of EU citizens: usually yes, within 72 hours to your national data protection authority.
Can I insure myself against this?
Cyber insurance exists, but it mainly covers the damage afterwards. Prevention is cheaper: the usual causes can be found automatically in advance.
