The privacy policy states that data is stored in data centres located in Europe, without naming the country, and that data is not shared with third parties without consent unless legally required. The company does not publish an ownership structure. For a European organisation, the operator and its data storage are within the EU, while the exact data-centre location and sub-processors should be confirmed in the data processing agreement.
