Whether you need to convert miles to kilometers, pounds to kilograms, or Celsius to Fahrenheit, there’s an app for that. But have you ever wondered what these apps do with your data? Do they track your location, your device, your usage, or even your identity? And if they do, can you stop them by using a VPN? A VPN can help you hide your IP address from the unit conversion apps, but it may not be enough to prevent them from tracking you. Some apps may use other methods to collect and share your data, such as browser fingerprinting, tracking cookies, device identifiers, or permissions. These methods can reveal information about your device, browser, location, preferences, and behavior, even if you use a VPN. Therefore, a VPN is not a foolproof solution for online privacy but rather a useful tool that can enhance your security and anonymity. While a VPN masks your real IP address, apps can still collect and track the IP address of the VPN server you are connected to.
