NEW YORK TIMES - Jan 13 - Popular dating services like Grindr, OkCupid and Tinder are spreading user information like dating choices and precise location to advertising and marketing companies in ways that may violate privacy laws, according to a new report released by the Norwegian Consumer Council, a government-funded nonprofit organization in Oslo. Grindr also sent a user's location to multiple companies, which may then share that data with many other businesses, the report said. OkCupid app sent a user's ethnicity and answers to personal profile questions to a firm that helps companies tailor marketing messages to users. OkCupid has recently posted a list of ~300 advertising and analytics "partners" with which it may share users' information. Tinder sent a user's gender and the gender the user was looking to date to two marketing firms. The Norwegian group said it filed complaints asking regulators in Oslo to investigate Grindr and five ad tech companies for possible violations of the European data protection law.
