    TikTok unlawfully tracks your shopping habits – and your use of dating apps

    A user discovered TikTok knew he had used the gay dating app Grindr and what he did there, data likely passed via AppsFlyer, an intermediary. TikTok also gave only an incomplete, hard-to-parse response to his GDPR access request across multiple attempts. noyb argues neither AppsFlyer nor Grindr had a valid legal basis under Article 6(1) or Article 9(1) GDPR to share this special-category data with TikTok.
