effi is completely safe

Are you wondering whether account analysis is safe? Yes! We work with an account information service (finAPI) that reads your account transactions via a secure interface. To do this, you log into your online banking via an encrypted connection. You also authenticate yourself with a TAN. Our service provider finAPI is licensed by BaFin (Federal Financial Supervisory Authority) and works in full data protection compliance. The legal basis for this service is the EU Directive PSD2 (Second Payment Services Directive), which came into force in 2019. The aim of the directive is to enable new, useful financial services for consumers.
