Android users may be unknowingly exposing their precise location to advertising companies through trusted mobile apps, according to a new report by the Electronic Frontier Foundation (EFF). The digital rights organization says the issue is not necessarily caused by the apps themselves but by third-party advertising software development kits (SDKs) integrated into many popular applications. Unless developers manually review and disable unnecessary data collection settings, users’ location information could continue to be shared with third parties. It also called on regulators and lawmakers to increase oversight of companies whose advertising software facilitates large-scale location data harvesting. The report specifically identified InMobi, BidMachine, Verve’s HyBid and Huawei’s Petal Ads among the advertising SDKs that collect and share location data by default.
