August 4, 2026 — The Electronic Frontier Foundation (EFF) has alerted Android app developers to a potential privacy risk where third-party code integrated into their applications may collect and share user location data, even when developers are unaware.

EFF Warns Android Developers About Third-Party Location Data Sharing
New findings from the Electronic Frontier Foundation (EFF) are alerting Android app developers to a significant privacy concern. The EFF has identified that certain third-party code, known as software development kits (SDKs), integrated into apps may collect users’ precise location data when users grant location permissions to the primary app.
The foundation states that many developers may not realize this data sharing occurs by default. The EFF is urging app makers to proactively disable unnecessary data collection within these third-party SDKs to protect user privacy and prevent inadvertent sharing of sensitive location information.
How Third-Party SDKs Collect and Monetize Location Data
Software development kits (SDKs) can inherit an app’s granted permissions. Unless a developer actively disables the collection feature within the SDK, it will automatically collect the user’s precise location data alongside the app’s intended functions. This can happen even if the app itself does not require precise location access for its core features.
Advertising SDKs are often integrated by developers as a method to monetize their applications. However, the EFF’s research indicates that a significant trade-off is the automatic transfer of users’ location histories to data brokers. These brokers, in turn, monetize this information by selling it to various entities, including government agencies and militaries.
Scope of the Location Data Sharing Issue
The EFF identified several Android applications that were unknowingly sharing user location data with third parties. Two of these applications alone had been downloaded a combined 60 million times. This highlights the potential reach of the issue, even if the examined SDKs represent a fraction of the overall advertising ecosystem.
Bill Budington, a senior staff technologist at the EFF, explained that the SDKs analyzed in their study, while a small part of the advertising landscape, collectively claim to reach billions of users across tens of thousands of applications. This points to the widespread nature of this data collection practice.
Key Facts About Android Location Data Sharing
- The Electronic Frontier Foundation (EFF) has identified a privacy issue in Android apps.
- Third-party software development kits (SDKs) within apps may collect user location data by default.
- Developers might be unaware that their app’s location permissions are being inherited by these SDKs.
- Collected location data is reportedly shared with data brokers, advertisers, governments, and militaries.
- Two affected apps identified by EFF have a combined download count of 60 million.
- The EFF urges developers to disable unnecessary data collection in SDKs.
Developer Responsibilities and User Consent
The EFF’s report emphasizes that app-level location permissions alone are insufficient to ensure meaningful user consent for data collection and sharing by third-party SDKs. The foundation argues that entities providing SDKs often have commercial incentives to encourage more data collection.
The EFF stated that advertising SDKs should not make the sharing of personal data, especially sensitive location data, the default setting. This practice undermines user privacy and control over their personal information, as users may not fully understand the implications of granting app permissions.
Potential Solutions and Future Implications
While the EFF has raised concerns, Google has previously introduced privacy features for Android. For example, the Photo Picker API, introduced with Android 13 in 2022, was designed to strip GPS coordinates from photos shared with apps, as a privacy measure. However, this also impacted apps that legitimately rely on geotagged data.
Reports suggest Google is developing further location-sharing controls for its Photo Picker, indicating an ongoing effort to balance user privacy with application functionality. Future Android versions are also expected to include new location privacy features to provide users with enhanced control and transparency.
Frequently Asked Questions
Are Android app developers unintentionally sharing user location data?
Yes, the Electronic Frontier Foundation (EFF) reports that many Android app developers may be unintentionally sharing their users’ precise location data. This occurs when third-party code, such as SDKs, integrated into their apps inherits location permissions granted by the user to the main application.
How do third-party SDKs collect and use user location data?
Third-party SDKs can collect user location data by inheriting the precise location permissions granted to the main app. Unless developers disable this function, the SDKs automatically gather this data. The collected information is then often fed to data brokers for monetization.
How widespread is the issue of Android apps sharing user location data?
The issue appears to be widespread. The EFF identified two Android apps sharing location data that had a combined total of 60 million downloads. While the specific SDKs examined are a subset of the advertising ecosystem, they collectively claim to reach billions of users across tens of thousands of apps.
What is Google doing about location data privacy?
Google has implemented privacy features like the Photo Picker API, which strips GPS data from shared photos. Evidence suggests further controls are in development for the Photo Picker, and future Android versions are expected to introduce more robust location privacy features to give users greater control.
