Mullvad VPN has announced that its Android app builds are now reproducible starting with version 2025.2, allowing users to verify that the app is built from the open-source code published by Mullvad. Reproducible builds ensure that the published source code matches the distributed application and that no unintended modifications occurred during the build process. Mullvad encourages users to engage in the verification process, providing source codes and instructions on its GitHub page.
