Some apps use design to trick you into sharing data. A new bill would make that illegal.

The bipartisan legislation also proposes extra protections for kids online, including the end of autoplaying video and many types of habit-forming design.

When using an app, how many times have you seen a cute, unobtrusively designed pop-up that asks you to share your location? Or an app onboarding process that makes access to your contacts just another button to click to get started?

This type of design makes it easier to consent to giving up personal information — whether or not you actually understand what you’re doing — than it does to seriously consider your options. It’s called a “dark pattern,” a term coined by user experience designer Harry Brignull in 2010 and popularized over the past few years. Technologists, regulators, and consumers have all started asking more specific questions about how apps can be created to look friendly and harmless even when they’re exploiting us, and this is one of the biggest topics of conversation.

Sens. Mark Warner (D-VA) and Deb Fischer (R-NE) introduced a bipartisan bill on Tuesday that would make this type of design illegal, affecting any social media platform with more than 100 million monthly active users.
