The owner field has a default suggestion that reads like this:
Individual, company or any other entity responsible for the application.
E.g. iubenda s.r.l - Via Torino, 2 - 20123 Milan (Italy)
In addition to this very simple owner statement you can use some html tags such as bold, italic, etc.
More than pure stylistic options, this opens up additional disclosure options for you. You can add whatever information you need to, such as for example, an appointed person/data processor. You can see an example on this screenshot:
The “owner contact email” will be added automatically to this very same section, pre-populated from the email form field below the owner field.
