Privacy Concerns Surround TikTok and Grindr's Data Sharing Practices

A privacy advocacy group, None of Your Business (noyb), has lodged formal complaints against TikTok, Grindr, and AppsFlyer, alleging violations of European Union privacy laws. The complaints were filed with Austria's data protection authority, claiming that these companies improperly shared sensitive user data without consent, particularly concerning sexual orientation, which is protected under the General Data Protection Regulation (GDPR). Noyb asserts that TikTok tracked a user's activity on Grindr through AppsFlyer, raising significant concerns about unauthorized data transfers and breaches of privacy regulations.

Noyb's allegations stem from a user's data-access request, which revealed that TikTok had accessed sensitive information from various apps, including Grindr and LinkedIn. The organization argues that neither Grindr nor AppsFlyer had the legal grounds to share this data with TikTok. TikTok has stated that the data was utilized for purposes such as personalized advertising and analytics, but critics argue that this practice violates GDPR's transparency requirements.

This is not the first instance of privacy concerns for TikTok and Grindr. In May 2025, the Irish Data Protection Commission fined TikTok €530 million for unlawfully transferring personal data of users in the European Economic Area to China. Additionally, Grindr is facing a class-action lawsuit in the UK, where users allege that the app shared their HIV status with third parties without consent between 2018 and 2020. This lawsuit has reportedly garnered over 11,000 signatories.

While no representatives from TikTok, Grindr, or AppsFlyer were immediately available for comment, TikTok previously defended its data-sharing practices, emphasizing that the information was used for security and advertising purposes. Noyb has urged Austrian regulators to impose fines and enforce compliance with GDPR, highlighting the potential risks of discrimination stemming from unauthorized access to sensitive information.

Critics of TikTok and Grindr's data-sharing practices argue that the companies have consistently failed to protect user privacy. Noyb's complaints reflect broader concerns about how tech companies handle sensitive data, particularly regarding vulnerable populations such as the LGBTQ+ community. The allegations have sparked discussions about the adequacy of existing privacy regulations and the need for stricter enforcement to safeguard user information.

While Noyb's complaints detail specific instances of data sharing, the companies involved have not publicly confirmed the allegations. The lack of immediate responses from TikTok, Grindr, and AppsFlyer leaves gaps in the narrative, particularly regarding their defense against the claims made by noyb.
