How We Investigated Personal Finance Apps: Methods, tips and challenges

The investigators behind "The Depth of Your Virtual Purse: What do fintech apps know about you?" talk about the methodology, tools, findings and challenges faced along the way.

The webinar discusses the making of a recent investigation - conducted by, Tactical Tech and SocialTIC - into how financial technology (fintech) apps focused on personal budgeting handle their users’ data privacy, but also how users themselves manage their personal information inside these apps.

More about the investigation: The Depth of Your Virtual Purse: What do fintech apps know about you?

Investigators used the EU's GDPR (General Data Protection Regulation) mechanisms to obtain and analyse the types of user data collected by the apps as well as what happens to this data within and beyond the apps.

The findings were quite intriguing:

  • a company handed data about the wrong user;
  • an app refused initially to provide data as required by law;
  • evidence of aggressive trackers accessing users’ personal data, and the use of automated user profiling mechanisms;
  • sensitive personal data and private habits get shared for advertising purposes, and are sometimes transferred to countries not covered by the GDPR, such as the United States.

In this webinar, investigators talk about how the methodology was designed and adapted along the way, the challenges faced from different sides and the intriguing findings uncovered. They also discuss the ways forward, how such research can be replicated, and what app users themselves could and should do to gain more awareness of their digital rights and claim control over their data.
