What is a modified version of the ProtonVPN app (APK)?

A modified version of the ProtonVPN app, commonly referred to as a "modded APK," is an altered form of the original application developed by Proton Technologies AG, intended for use on Android devices. This type of modification usually involves unauthorized tampering by third parties who are not affiliated with the official developers. Such modifications can include the removal of restrictions or limitations present in the original app, such as subscription requirements or usage limits. Modded APKs may also contain additional features or functionalities that are not available in the genuine version of ProtonVPN. However, it is important to note that using modified versions can pose significant risks including security vulnerabilities, privacy breaches, and potential infringement of copyright law, as they have not been vetted through the standard security protocols of the original developer.
