Dan Hastings, a security consultant at NCC Group, analyzed some of the most popular robocall-blocking apps and found that when you download these apps, you may be trading one evil for another.
Why? Because these apps violate your privacy as soon as they’re opened.
One app, TrapCall, sent users’ phone numbers to third-party analytics firm AppsFlyer without telling users.
Robocalls have become a major issue for consumers. So much so, that the FTC and FCC have started taking legal action against companies and individuals accused of placing spam calls.
Additionally, earlier this year the FCC voted to let phone companies block robocalls by default. However, the vote does not prohibit carriers from charging users for such a service, so many consumers have turned to free apps. And while these apps may provide a cost-effective solution, they’re creating another problem for people’s privacy.
“If most people took the time to read and try to understand privacy policies for all the apps they use (and are able to understand them!), they might be surprised to see how much these apps collect.”
