But some apps are also inadvertently sharing their users’ location data with third parties, including advertisers and data brokers, because the app developer may not know that this data-sharing setting is enabled by default. The EFF says many developers might not realize that they are sharing their users’ location data with third parties by default and urged app makers to disable unnecessary data collection whenever possible. The EFF’s report said that there are “no SDK-specific location permissions,” meaning that once the user allows their location data to be shared with the app, their location data is also shared with advertisers. “App-level location permissions alone cannot signal meaningful consent to location collection and sharing by third-party advertising SDKs,” wrote the EFF. “Advertising SDKs should not make sharing personal data the default, especially for data as sensitive as a person’s location.”
