Your flings on Tinder may be short-lived — but your personal information stays with the hookup app forever.

That’s the concern being flagged by a European consumer advocate, which claims that Tinder may allow its users’ sensitive personal info to be distributed to third parties without their consent — even if they’ve deactivated their accounts.

The fine print in Tinder’s user agreement — which, in the US and abroad, permits sign-ups for cruisers as young as 13 — runs afoul of privacy laws in the European Union and in Norway, the Oslo-based group said.

“This permission granted to Tinder by the user is far-reaching and would appear to be infinite,” the Norwegian Consumer Council (NCC) wrote in a report to the country’s consumer ombudsman.

Tinder — whose chief executive, Sean Rad, has lately faced heat over a slew of embarrassing public gaffes — faces a possible overseas regulatory investigation that could result in fines or demands that Tinder change its user terms.

In a written response to The Post on Thursday, Tinder didn’t specifically deny the Norwegian advocacy group’s claims, saying only that it is “committed to protecting our users’ privacy and strive to uphold a fair and trusted privacy policy.”

“At Tinder, we make every effort to comply with all local and national regulations, privacy and otherwise,” the statement said. “If and when authorities bring up larger privacy concerns, we always take them into consideration and, if applicable to our users, take steps to implement any necessary changes.”

Tinder stores and shares user information with Tinder’s business partners, which “may hold the same far-reaching rights and licenses as Tinder,” according to the watchdog’s report.

The NCC also griped that Tinder users can’t permanently delete their accounts, potentially leaving personal data exposed indefinitely.

“As far as we can tell, it is only possible to deactivate an account,” the report said. “The contractual relationship continues even if the user is no longer using the service.”
