Lockdown, a new app launching today, is designed to be an open source firewall, letting users block any connection to any domain, including those that use ad tracking services and analytics platforms to monitor device usage.

Lockdown is free to download and use, and because it operates on device, it collects no user data. Lockdown uses Apple's VPN setup to function, though it is not a VPN and will not obscure your own IP address.

lockdownapp
Using Lockdown, you can block any domain, including those from companies like Facebook, and the app comes with a pre-set list of recommended domains to block to prevent tracking. Facebook tracking and other analytics tracking options from companies like Google, Mixpanel, and more are automatically blocked upon installing the app, and you can add your own custom lists too.

In addition to preventing unwanted tracking, the Lockdown app promises faster browsing speeds because unwanted connections are blocked, saving loading time.

Lockdown comes from the team behind Duet Display, and in the future, the app will offer a paid option that includes VPN functionality. Lockdown's developers are hoping that the launch of the app will incentivize developers to use more privacy-focused analytics frameworks and app discovery methods that rely less on trackers from major companies like Google and Facebook.

Lockdown can be downloaded from the App Store for free. [Direct Link]

I blocked The Facebook beta and Email Opens and now both appear as being Blocked and Unblocked!

Will fix this in the next version! Sorry about that, always a couple bugs on launch day :)

I use Firefox Focus to block trackers.
Not the same thing. Firefox cannot block analytics and tracking SDKs that are embedded in many apps. This can.

If I chose to use this app without the paid VPN service, does this mean my internet traffic (my information) won't be monitored at all by the developer?

I mean we all know we trade in our privacy when we pass our connection through a VPN and the private company can monitor our connection. I'd like to know if my connection (and the data packages of each app) is going to be monitored by any means, like they are when passing through a VPN, or the firewall works totally on device.

Thank you.
We will never monitor or sell your Internet traffic (Lockdown is an on-device firewall, so the data never leaves your device). Since the free version has no server cost or marginal cost per user, we believe that part of the product should be free.

I write code. My career has been sustained by fixing the very bugs I myself created. Thanks for the quick reply; at least someone is listening!
