When you applied for health insurance through your state marketplace, you trusted the government with some of your most sensitive personal information. Your income. Your family status. Your race. Whether you have an incarcerated family member.

That information didn't stay private.

A new Bloomberg investigation reveals that nearly all 20 state-run health insurance exchanges shared residents' application data with advertising giants including Google, Meta, LinkedIn, TikTok, and Snap. The culprit is a common tool called a pixel tracker, a tiny piece of code embedded in websites that allows tech companies to collect information about visitors. On a shopping website, that might mean tracking what you browse. On a government health insurance exchange, it means your most personal details flowing directly into advertising algorithms.

The scale of this is staggering. More than seven million Americans purchased health insurance through a state exchange this year alone.

New York's exchange shared whether applicants have incarcerated family members. Washington D.C.'s exchange shared residents' race with TikTok, along with email addresses, phone numbers, and country identifiers. Virginia's exchange was sharing ZIP codes with Meta. These are not minor technical glitches. They are systemic failures that put vulnerable people at real risk.

For immigrant families, for people with incarcerated loved ones, for anyone whose race or personal details could be used to target or harm them, this is not an abstract privacy debate. This is a safety issue.

Some states have started removing trackers after Bloomberg's investigation went public. That is not enough. Americans deserve to know exactly what was shared, with whom, and for how long. And they deserve a federal law that makes sure it never happens again.

Sign this petition to demand Congress pass legislation banning advertising trackers on government websites that collect sensitive health and personal data, and to require every affected state to notify residents whose information was shared.
