An investigation, conducted by the Mozilla Foundation, into the data safety labels and privacy policy on the Google Play Store has exposed some severe loopholes that enable apps like Twitter, TikTok, and Facebook to give inaccurate or misleading information about how user data is shared.
The study was conducted between the 40 most downloaded Android apps, out of which 20 were free apps and 20 were paid, on Google Play and found that nearly 80% of these apps disclose misleading or false information.
The following findings were made by the Mozilla researchers:
- 16 of these 40 apps including Facebook and Minecraft, had significant discrepancies in their data safety forms and privacy policies.
- 15 apps received the intermediate rating, i.e. “Need Improvement” indicating some inconsistencies between the privacy policies and the Data Safety Form. YouTube, Google Maps, Gmail, Twitter, WhatsApp Messenger, and Instagram are some of these applications.
- Only six of these 40 apps were granted the “OK” grade. These apps included Candy Crush Saga, Google Play Games, Subway Surfers, Stickman Legends Offline Games, Power Amp Full Version Unlocker, and League of Stickman: 2020 Ninja.
Google’s Data Privacy Section
Google apparently launched its data privacy section for the Play Store last year. This section was introduced in an attempt to provide a “complete and accurate declaration” for information gathered by their apps by filling out the Google Data Safety Form.
Due to certain vulnerabilities in the safety form's honor-based system, such as ambiguous definitions for "collection" and "sharing," and the failure to require apps to report data shared with "service providers," Mozilla claims that these self-reported privacy labels may not accurately reflect what user data is actually being collected.
In regards to Google’s Data Safety labels, Jen Caltrider, project lead at Mozilla says “Consumers care about privacy and want to make smart decisions when they download apps. Google’s Data Safety labels are supposed to help them do that[…]Unfortunately, they don’t. Instead, I’m worried they do more harm than good.”
In one instance in the report, Mozilla notes that TikTok and Twitter both confirm that they do not share any user data with the third parties in their Data Safety Forms, despite stating that the data is shared with the third parties in their respective privacy policies. “When I see Data Safety labels stating that apps like Twitter or TikTok don’t share data with third parties it makes me angry because it is completely untrue. Of course, Twitter and TikTok share data with third parties[…]Consumers deserve better. Google must do better,” says Caltrider.
In response to the claim, Google has been dismissing Mozilla’s study by deeming its grading system inefficient. “This report conflates company-wide privacy policies that are meant to cover a variety of products and services with individual Data safety labels, which inform users about the data that a specific app collects[…]The arbitrary grades Mozilla Foundation assigned to apps are not a helpful measure of the safety or accuracy of labels given the flawed methodology and lack of substantiating information,” says a Google spokesperson.
Apple, on the other hand, has also been criticized for its developer-submitted privacy labels. The 2021 report from The Washington Post indicates that several iOS apps similarly disclose misleading information, along with several other apps falsely claiming that they did not collect, share, or track user data.
To address these issues, Mozilla suggests that both Apple and Google adopt an overall, standardized data privacy system across all of their platforms. Mozilla also urges that major tech firms shoulder more responsibility and take enforcement action against apps that fail to give accurate information about data sharing. “Google Play Store’s misleading Data Safety labels give users a false sense of security[…]It’s time we have honest data safety labels to help us better protect our privacy,” says Caltrider.
