Digital female health

Clue helps everyone who menstruates to understand their bodies—and to be empowered by that knowledge. Our vision is to enable women and people with cycles to live in tune with their biology, not in spite of it.

Founded by Ida Tin, Clue is a VC-­backed startup based in Berlin helping over 10 million people each month get insights into their reproductive health via our Android and iOS apps. We collaborate with world-leading universities and institutes to advance female health research with our dataset, and deliver essential education about health, periods, and sex via our website, helloclue.com.

A new study shows how popular apps, including Grindr, OkCupid, Tinder, and the period-tracking apps Clue and MyDays, share intimate data about consumers with dozens of companies involved in the advertising business.

The details include data that could indicate users’ sexual orientations and religious beliefs, along with information such as birthdays, GPS data, and ID numbers associated with individual smartphones, which can help tie all the data back to a single person.

The study, conducted by an advocacy group called the Norwegian Consumer Council, examined 10 apps and found that they were collectively feeding personal information to at least 135 companies. The list of companies receiving the information includes household names such as Amazon, Facebook, and Google, but the majority are little-known outside the tech industry, such as AppsFlyer, Fysical, and Receptiv.
