About this app

Bitmask is a 100% open source censorship-bypassing VPN from LEAP Encryption Access Project. It is one app that allows you to connect to multiple trusted VPN providers. Bitmask is third-party audited, fast, secure, super easy to use, and free! You just install it and run it—zero configuration, zero registration. Bitmask and our partner providers do not require user accounts, keep logs, or track you in any way.

OUR TRUSTED VPN PROVIDERS

VPNs help protect your privacy and secure your online activity, but it’s super important to use a trusted VPN provider. With Bitmask you can select from our trusted service providers riseup.net and The Calyx Institute. Riseup.net is a longtime provider of online communication tools. Their email and mailing lists are used by hundreds of thousands of users around the world. The Calyx Institute has a long track record of educating users about the threat of online surveillance and providing tools to protect their privacy.

OPEN SOURCE AND THIRD PARTY AUDITED

Like any good VPN, Bitmask helps you to protect your internet traffic against mass surveillance, enhances your online privacy, and can help bypass censorship. Specifically, Bitmask
– is third party audited and uses only open source technology
– encrypts and protects your traffic from the spying eyes of your internet service provider
– secures your browsing traffic on public and private Wi-Fi networks
– hides your IP and your real location from websites and online services
– circumvents censorship and allows you access to blocked content

THIS IS A FREE, DONATION-FUNDED SERVICE

Bitmask is free to use and funded by donations from users like you. We believe everyone should have access to secure communication tools. Your donations keep Bitmask operational. Thank you!

DEVELOPED BY LEAP ENCRYPTION ACCESS PROJECT

Founded in 2012, LEAP is dedicated to giving all internet users access to secure communication. There are many fronts in the fight against the enclosure of the internet and the relentless efforts to surveil and monetize our lives. LEAP is part of the growing effort to expand the use of circumvention technology to protect us from government and corporate incursion into our online lives. LEAP builds and brands RiseupVPN, CalyxVPN, and Bitmask. https://leap.se

Best vpn service available. Hides both ipv6 and ipv4. Solid fast and reliable connection that is 100% free and easy to use. And for that I have donated many times! That's how it should be done. Provide a good app and service and people will appreciate it and want to support it. Don't fill it with ads and try to force a subscription on them by limiting it's functionality! Hats off to it's creators!

I have mixed feelings regarding this app. Initially, it worked as it should. Over the past two weeks it has begun to stop functioning. Currently, the VPN will not connect at all. I get a message "Try Obfuscated Connection" so I select that, then another message appears "Try Standard Connection". Regardless the option I select, the VPN will not connect. One thing I have not tried is to remove the app then reinstall.
