Uncovering Relationships between Android Developers, User Privacy, and Developer Willingness to Reduce Fingerprinting Risks

2026-03-30

AI Summary

Although mobile platforms have strengthened privacy protections, device fingerprinting remains widely used for covert user tracking, and the collaborative dynamics between developers and platforms remain unclear. This study investigates 246 Android developers through a survey embedded with hypothetical policy change scenarios to quantify their awareness of privacy interventions, willingness to mitigate tracking risks, and trade-offs regarding implementation costs. Findings reveal that 89% of developers support stronger privacy protections even at the cost of increased development burden, preferring optional over mandatory measures. Developers familiar with fingerprinting techniques exhibit significantly reduced perceived gaps in privacy capabilities between iOS and Android. Notably, those actively using fingerprinting are more supportive of privacy-enhancing improvements. These results underscore developers’ proactive role in privacy compliance and implementation, offering empirical grounding for new collaborative approaches to platform–developer privacy governance.

Abstract

The major mobile platforms, Android and iOS, have introduced changes that restrict user tracking to improve user privacy, yet apps continue to covertly track users via device fingerprinting. We study the opportunity to improve this dynamic with a case study on mobile fingerprinting that evaluates developers' perceptions of how well platforms protect user privacy and how developers perceive platform privacy interventions. Specifically, we study developers' willingness to make changes to protect users from fingerprinting and how developers consider trade-offs between user privacy and developer effort. We do this via a survey of 246 Android developers, presented with a hypothetical Android change that protects users from fingerprinting at the cost of additional developer effort. We find developers overwhelmingly (89%) support this change, even when they anticipate significant effort, yet prefer the change be optional versus required. Surprisingly, developers who use fingerprinting are six times more likely to support the change, despite being most impacted by it. We also find developers are most concerned about compliance and enforcement. In addition, our results show that while most rank iOS above Android for protecting user privacy, this distinction significantly reduces among developers very familiar with fingerprinting. Thus there is an important opportunity for platforms and developers to collaboratively build privacy protections, and we present actionable ways platforms can facilitate this.
