Grindr had a big data "leak" in 2024.[1] Not a "leak", really, just ordinary reselling of people's gay and HIV status. In 2025, a data broker who resold Grindr data also had a big breach. That wasn't Grindr-specific - it included Temple Run, Subway Surfers, Tinder, Grindr, MyFitnessPal, Candy Crush, Truecaller, 9GAG, Microsoft 365, and others. But not TikTok, because TikTok monetizes that info themselves.
