    Mullvad VPN desktop and mobile app

    Mullvad VPN desktop and mobile app

    The Mullvad VPN client app for desktop and mobile

    In a society that is increasingly determined to weaken that right, a fast, reliable and easy-to-use VPN connection is a good first step towards achieving this. By connecting to the Internet with Mullvad, we ensure that traffic to and from your device is encrypted to the highest standards, even when using public Wi-Fi in a coffee shop or hotel. We do not keep activity logs or ask for personal information, and we even encourage anonymous payments using cash or any of the accepted cryptocurrencies. Your IP address will be replaced with one of ours, ensuring that device activity and location are not linked to your user. Using Mullvad is quick and easy - just download and install the app. Don't spend time on complicated setup and multi-step registration processes. We designed Mullvad to be easy to use. Privacy is essential in a well-functioning society, as it allows norms, ethics and laws to be safely debated and challenged. Without privacy, a free and open society cannot flourish or exist.

    IOS6 and recent iTunes updates have broken a few features. We have made some partial fixes, but they are not complete. If you'd like to help support our development, or take over the development please let us know. Explore the internal file structure of your iphone (or of a seized phone in the case of forensic teams) using either the iphone's own backup files or (for jail broken iphones) ssh. Viewing of plist, sqlite, and hex are supported. IOS 5 is now supported iOS 6 only partially works at the moment (some features fail or are missing). Unfortunately paid work means we can't fix this right now, but would welcome anyone else submitting patches.
