REUTERS – Austrian privacy group NOYB has filed complaints against TikTok, Grindr, and AppsFlyer, alleging they violated EU GDPR rules by tracking users across apps and sharing sensitive data without consent. NOYB says a user discovered, through a data-access request, that TikTok had accessed information about their Grindr activity, along with data from other apps, via AppsFlyer. The group claims TikTok used this information for personalized ads, analytics, and security, and that neither Grindr nor AppsFlyer had legal grounds to transfer such data. NOYB is urging regulators to issue fines and halt the practices.
