Free VPN apps may sell user data or hide malware

Free virtual private network applications available on mobile app stores may compromise user privacy by collecting and selling personal data or containing malicious software. Users often install these tools to access blocked websites, improve online gaming performance, or secure connections on public networks, believing their digital identity is fully hidden. However, cybersecurity experts report that many of these free services track user activity extensively despite advertising strict no-logs policies. The cost of maintaining high-speed servers and employing engineering teams is significant, leading to questions about how these companies sustain operations without charging users. Reports indicate that free VPN providers often monitor which websites users visit, which applications they use, and for how long.

They also log location data and unique device identifiers. This collected information is bundled and sold to third-party data brokers, advertising firms, and marketing agencies. In some cases, weak server security has resulted in private information leaking onto the dark web. Beyond data theft, free VPN apps pose risks to device health. Global cybersecurity research suggests that approximately 35 to 40 percent of these applications contain hidden trackers, adware, or spyware code. After installation, users may experience unwanted pop-up advertisements, increased background internet consumption, and rapid battery drain. A more severe risk is network hijacking, where some free providers silently turn user devices into residential proxies. This allows unknown individuals to use the user's internet connection and IP address for cybercrime.
