KOSA Privacy Warning: More Age Checks Can Mean More Sensitive Data Collection

The Electronic Frontier Foundation warned that the U.S. Senate Commerce Committee is again considering the Kids Online Safety Act, known as KOSA, alongside several other child-safety and online-content bills. EFF argues that KOSA's duties would push online services to know which users are minors, creating pressure for more age verification or age estimation systems.

In a separate post about the committee's package, EFF says KOSA, the SCREEN Act, the Youth AI Privacy Act and the CHATBOT Act point in the same direction: more age gates, more data collection and more restrictions on lawful online speech. The bills are U.S.-focused, but the privacy trade-off is relevant anywhere platforms respond globally to compliance risk.

Age checks are often presented as a narrow safety tool, but the implementation details matter. EFF notes that services may verify or estimate age through government ID checks, facial analysis, bank-record checks or other personal information. Each option can create a sensitive trail linking identity, age, device and online activity.

For ordinary users, the privacy concern is not only whether a law applies to one category of content. Once platforms build age-assurance systems, the same verification flow can spread across forums, social networks, search features, messaging tools and other mainstream services. That means more places where people may have to identify themselves before reading or participating online.

Watch for services that ask for ID, face scans, payment details or third-party age-verification handoffs, and read what data is stored, who receives it and how long it is retained. Prefer services that minimise data collection, offer parental controls without broad identity checks, and clearly separate child-safety settings from advertising or profiling systems.

Families can use device-level controls, app-store settings, privacy-preserving filters and direct conversations about online risk without assuming every platform should collect more identity data. Policymakers and platforms should publish privacy impact assessments before rolling out age checks at scale.

A VPN can reduce passive IP-based location tracking and can make it harder for a local network or ISP to see which sites you visit. That may help protect general browsing privacy, especially on shared or public networks.

But a VPN should not be treated as an age-check bypass tool. It cannot protect a passport scan, face scan or payment record that you submit to a website or verification vendor. It also cannot remove legal obligations from a platform or make risky workarounds safe. For age-assurance systems, data minimisation and transparent rules matter more than IP masking.

VPN Rocks supports practical online safety, but safety rules can backfire when they require everyone to prove who they are before using ordinary parts of the internet. The privacy question to ask is: what new database is being created, who can access it, and what happens when it leaks?

If a site asks for age verification, do not assume a VPN solves the privacy issue. Look for the least invasive route, avoid uploading more data than necessary, and use a VPN as one network-privacy layer rather than a replacement for cautious identity sharing.
