Lockdown is the world's first Open Source firewall for iOS, allowing you to block any connection to any domain and protecting your privacy across the web. For free.

- Block any domain / service
- Works for all apps, not just the browser
- Useful preconfigured defaults
- See what's being blocked
- Optional VPN for additional privacy

- Open Source: Since firewalls have access to *everything* you do, it's critical that any firewall you use should be open source. Lockdown is 100% open source.
- On-Device: Lockdown does its magic on-device and doesn't connect to any servers, or third-party analytics, or anything else. This way, everything you do stays private to you.
- World's Simplest Privacy Policy: Here's the entirety of it (July 23rd, 2019) - "Everything Lockdown does stays on your device, so what you see is literally what you get, and nothing more or less, because that's the way it should be."

Lockdown is essential in today’s world

By now you’ve probably heard all the privacy issues companies such as Facebook and Google are causing by harvesting and selling your personal information. It almost seemed impossible for privacy to exist in a smart phone world with so many entities tracking your every move.

Lockdown has provided an amazing way to take back and protect your right to privacy.
This app is great. Such an innovative idea and it works great with my existing VPN. A much needed tool in the balancing act between having access to information while not allowing providers to compromise your personal privacy and security.

This latest version is super solid and allows the rest of my phone to continue to access Apple mail and my other essential services while giving me the peace of mind to know I can control my information by limiting the trackers that booby-trap the Internet.

I don’t usually leave reviews but when I do it’s for a product so awesome, I want to support it to ensure it remains available to help protect our privacy from the prying eyes of private corporations.

Thank you Lockdown!

VPN doesn’t mean sending data; Incompatible with

Firstly to the people wondering about the VPN profile this app sets up. That’s the only way any app can handle system wide network traffic on iOS. So every “firewall” or DNS app will setup a VPN profile. This doesn’t necessarily (or always) mean that your data is being sent to a VPN server, depending on the app.

Lockdown Devs: this is currently not compatible with the DNS setup through the Cloudflare app. Your VPN profile shows up in the same section as, and iOS doesn’t allow both to be selected. It’s a toggle allowing either or this one to be active at any point in time. Unless that’s resolved, by supporting the configuration of custom DNS within this app, it wouldn’t be useful for those who have third party DNS setup through apps like or DNSCloak. Also please work with Apple to see how two VPN profiles can handle traffic in a chain.

Great app

Update: I’ve stress tested the latest version and can’t find any issues. It “just works”, invisibly doing what it should. Great update!


I’m amazed at how much evil web traffic was going out my phone. This app stops it cold. Simple install and easy to set up - one button and a few options. Some growing pains for a new app but their support is very responsive and helpful. They are improving the app constantly. I love that you can set it and forget it. The only thing that ever broke for me was Mail and they had a updated version with a fix the next day. This should be a default install for every iPhone user!
