About & Contact
error404 is a small studio that builds native apps for Mac, iPhone, and iPad. It is the app brand of 9F B.V., a company registered in the Netherlands.
error404 is the name on the apps and on this website. 9F B.V. is the legal entity behind it: the company that publishes the apps, signs the developer agreements, and is responsible for support, privacy, and payments. Same people, same address, same inbox — one is a brand, the other is the company.
So if you see 9F B.V. on an App Store receipt, an invoice, or a developer page while you were expecting error404, that's the same business and not a mistake.
