According to reports, the Dutch Consumer and Markets Authority (ACM) announced on Wednesday that the agency is conducting a preliminary investigation into Google for possible violations of competition law in the Google Play store.
Match Group, which owns Tinder, has asked regulators to assess whether Google has abused its dominant position in the dating app market.
"It is alleged that dating app providers are no longer able to use payment systems other than Google Pay," Murco Mijnlief, an ACM spokesman, said in an email.
A Google spokesman responded that the company charges customers a 15 percent subscription commission through the Play Store, which Google said is "the lowest percentage of any major app platform." App distributors can also get around the Play store's cut entirely by distributing their apps through other stores or websites, Google said.
ACM is still engaged in a two-year battle with Google's rival Apple over alternative payment methods for dating apps on the App Store.
Apple has already received a fine of 50 million euros, the highest possible under the current court order, for failing to comply with an ACM order to allow dating app developers to offer users alternative payment methods.
On Monday, THE ACM said Apple's most recent remedy proposal, made on March 30, was still insufficient and that the agency was preparing a new order that would include new payment-related penalties.
ACM said: "Once we publish this new order requiring regular payment of fines, we will be able to comment on what is in it and the points that Apple still fails to comply with. The work could take several weeks." Apple previously said it believed it had fully complied with ACM's order and declined to comment further.
