Simple steps can protect your privacy and location data.
Before you join the Wi-Fi hotspot at your local cafe, you might want to make sure it won’t follow your footsteps—literally—after you leave.
Ostensibly “free” Wi-Fi hotspots are in hundreds of thousands of businesses and public spaces across the United States. They’re in shopping malls. In airports. In chain restaurants. In local cafes. As a result, it’s easier than ever to get online. If your notebook or phone lacks a reliable data connection, you can still connect to a hotspot. But this convenience often comes at a price: your personal data and privacy.
When you use “free” Wi-Fi, there’s a good chance it’s managed by a third-party provider—which gets you online in exchange for your valuable sign-on data. The sign-on information that hotspots require will vary, but often includes your email address, phone number, social media profile, and other personal information. All can be used to target you with advertising and gain insights on your habits.
As Emory Roane, policy counsel at Privacy Rights Clearinghouse (go.pcworld. com/part), told PCWorld: “Read through the Wi-Fi Terms of Use for any of these businesses and you’ll almost certainly realize that there’s still no such thing as a free lunch.”
That’s probably not a surprise to most Wi-Fi hotspot users. But what might surprise you is that some hotspot providers are taking data collection a step further, and quietly tracking millions of users’ whereabouts even after they’ve left an establishment. These hotspots are part of America’s burgeoning location-based Wi-Fi marketing industry.
PCWorld spoke to privacy experts and Wi-Fi location-analytics companies to learn more about how this technology works, and what you can do to avoid being tracked.
