Most online services that children use are likely monetizing their data in some way, according to a new report from Common Sense Media. The nonprofit analyzed the privacy policies of more than 200 popular internet platforms and found that about three-quarters of them were sharing user data or lacked transparency about how they use personal data. Disclosing those details and offering users a chance to opt out is required in California under the latest expansion of the state’s landmark privacy law, which was sponsored by Common Sense. A recent court ruling extended the deadline to comply with the new privacy provisions to March 29. Marketplace’s Meghan McCarty Carino spoke to Jim Steyer, CEO of Common Sense Media, about how many companies’ current privacy policies can be misleading.
