Grindr has agreed to pay £26 million ($35.1 million) to settle a UK class action lawsuit alleging that it shared users' sensitive personal data, including HIV status, with third parties. The claim, brought in England's High Court, drew on 2018 research showing Grindr had shared data such as HIV status, sexual orientation and GPS location with analytics firms Localytics and Apptimize, raising concerns that this information could be used to target advertising at users. Grindr has not admitted liability but acknowledged the "distress and loss of trust" felt by affected UK users during the pre-2020 period in question.

The claim was issued in April 2024 by law firm Austen Hays and served on Grindr in April 2025, covering alleged data-sharing violations before April 2018 and between May 2018 and April 2020. Under the settlement, Grindr will pay two £13 million instalments by December 2026 and March 2027. The company noted the conduct occurred while it was owned by China's Kunlun, before US regulators forced a sale, and says it has since overhauled its privacy practices. The sum is roughly five times a separate $6.9 million Norwegian fine, imposed in 2021 over similar data-sharing practices, which Grindr unsuccessfully fought through Norway's courts until October 2025.
