The regulator said the tool did not meet requirements set out in the GDPR, that people have a right to access the personal data about them that a company holds.

Deputy Commissioner at the Irish DPC, Graham Doyle, said automated access tools "can be a useful and efficient way" to give people access to their personal data, but they "must be fair and transparent to individuals regarding the extent of the data provided."

Match Group has been fined €11 million, issued with a reprimand, and ordered to bring its data processing into compliance with the GDPR within three months.

A Match Group spokesperson said the company will appeal: “Tinder engaged with the DPC throughout this investigation, and we stand behind the privacy protections we’ve built for our users.”
