Lockdown Privacy: AdBlock VPN promo code

Lockdown blocks trackers, ads and known malicious domains in every app on your iPhone, not only in the browser. Its firewall works on the device itself, so the blocking happens without routing your traffic through someone else's server.

Most people switch it on with one tap and rely on the block lists, which the developers refresh weekly; advanced users can block any domain they choose. Separately, Lockdown offers a paid VPN for keeping your connection private on public networks. The firewall's code is open source.
