Exploring Perceptions of Federated Learning in Self-Tracking Apps: A Qualitative Study with Mostly Female University Students
This study explores how Federated Learning (FL) can impact users' perceptions of privacy and data sharing in self-tracking apps, particularly among university students (mostly female). While FL's privacy-enhancing features were appreciated, trust in companies and understanding of data usage remained critical. Participants showed varying willingness to share data based on sensitivity and context, with a preference for privacy over accuracy in non-critical scenarios. The findings highlight the need for greater user education, tangible benefits, and trust-building measures for broader FL adoption, especially given users' existing privacy concerns and reluctance to share sensitive personal identifying information.

Contextual Privacy Importance
The majority of participants valued privacy, with its importance varying based on the type of data and context. While some felt digital privacy was an illusion, others were desensitized due to pervasive tracking. Acceptable data included activity and sleep, while personal information, location, audio, photos, and calls were deemed unacceptable unless anonymized. This highlights that privacy is not a static concept but rather fluid and dependent on individual perceptions of risk and utility.
Universal Data Security Concerns
Participants expressed universal concern for data security, fearing personal information being sold or misused by third parties and advertisers. Many believed tracking was unavoidable, citing customized advertisements as evidence of constant monitoring. A persistent lack of trust in companies, exacerbated by past data breaches and mishaps, contributed to these concerns. Participants desired strong safeguarding measures like end-to-end encryption to protect sensitive data.
Demand for Transparency
Most participants complained about the lack of transparency in data collection, finding 'terms and conditions' too lengthy and jargon-filled. They believed companies sometimes exploit legal loopholes. Trust in the organization was deemed a significant factor, independent of the technology used. Clear, concise, and upfront privacy terms were highly desired to enable users to make informed decisions about their data.
Limited Awareness of Data Storage
Participants were largely unaware of where their data was stored, often not reading privacy terms in detail. Some incorrectly assumed data was stored on their device, while others believed it was sent to a remote server. This highlights a missed opportunity for FL to address privacy concerns by emphasizing local data storage as a core benefit, and the need for better communication regarding data handling practices.
Organizational Trust Deficit
A general lack of trust in organizations was prevalent, with trust often depending on company reputation. Larger companies (e.g., Apple) were perceived as more trustworthy due to better resources and security measures. Participants expressed reluctance to engage with unfamiliar or negatively reputed brands, and some distrusted government bodies due to surveillance concerns. This suggests that the underlying technology alone cannot build trust without a reputable entity.
Desire for Data Control & Ownership
The majority of participants emphasized the need for ownership and control over their data, including the ability to opt in or out of data collection. Concerns were raised about automated data collection, where users felt they had no control. The ability to directly erase data from the app, account, and cloud at any given time was a key request, underscoring the importance of user agency in data management.

Balancing Privacy and Accuracy
Most participants preferred privacy over accuracy, especially for non-serious data tracking (e.g., steps). However, for health-related apps (e.g., blood sugar, mental health), accuracy was deemed equally or more important, with acceptable accuracy reductions ranging from 5-15%. Some would rather not use an app if it became too inaccurate or untrustworthy. The notion of AI complementing human judgment for serious conditions was also raised, indicating a nuanced trade-off based on application criticality.

Monthly Willingness to Pay for FL Apps (Varies by Context)
Factors Influencing Payment
Participants' willingness to pay for a privacy-enhanced app varied from £2-£10 per month, depending on app type (health vs. generic activity tracker), service value, and personal financial situation. Some would only pay if no free alternative existed. Reluctance to pay was also linked to low perceived consequences of data release or lack of trust in the technology. Financial constraints among students were a barrier, yet the majority indicated a need for privacy-friendly data collection solutions.
Positive Acceptance & Remaining Concerns
Most participants expressed satisfaction with FL as a significant privacy improvement due to local data storage, increased anonymity, and no third-party access or ad selling. This boosted faith in the system and encouraged maximizing app utility. However, some still held privacy concerns due to lack of experience, general distrust in AI, and insufficient awareness about FL's full benefits. Trust in the organization's reputation remained paramount, independent of the technology, with mixed views on trusting big tech companies post-breach, underscoring the need for working prototypes and hands-on experience.
