Generally, the cityapp can be used without the user needing to provide any personal data, though the user can select their preferred language (French, German or English).

In certain cases, the user may be asked to provide the following personal data on a purely voluntary basis:

  • User status: resident, worker or visitor
  • Surname
  • First name
  • Home address
  • Work address
  • Email address

These details may be requested in the following cases/for the following purposes:

  • Customisation of widgets
  • For the user's personal account, for the purpose of managing personal data stored on their smartphone, and pre-filling contact forms
  • Filling in contact forms (see point below).

Such data is stored only on the user's smartphone.

The only data stored on the City's servers are those used for the purpose of configuring widgets. Such data is anonymised, thus making it impossible to identify the user. As such, no connection with a natural person can be established.
