Does individual entrepreneurship exist in this situation?

The question does not contain context, so it is difficult to give a precise answer. In general, individual entrepreneurship is a form of business where a person independently conducts entrepreneurial activities without forming a legal entity.

If the situation is related to iOS (for example, app development), then individual entrepreneurship may be applicable if the developer registers as an individual entrepreneur for legal business activities, earning income, and paying taxes.

Without additional information about the situation, it is not possible to definitively say whether individual entrepreneurship exists.
