How Can We Safely Use These Apps?

"We have never sold your data and we will never sell your data," FEMTech says. "If you don't pay for the product you're using, you most likely are the product yourselves", it adds. In Europe, there is tough regulation but not in the U.S., where users aren't being checked as closely. So until they invent FEMTech tech to monitor these apps, I guess we'll just have to track them ourselves.
