Why It’s Different
A Filter List Can’t Catch Everything.
MachOne runs the community filter lists — and an in-page layer for what a list structurally cannot catch.
Lighter
Less for Pages to Load
Every ad and tracker request it blocks is data your device never downloads.
Private
Every Decision On-Device
No accounts, no analytics and no MachOne servers — so there is nowhere for MachOne to send the pages you visit. It goes online to download public filter lists, to look up some of a page’s addresses through your device’s DNS (to find disguised trackers), and to run the benchmark when you tap it. Every connection, listed
Proven
Don’t Trust It — Test It
The built-in benchmark requests real tracker scripts without MachOne’s rules, then with them, and scores what got through — on your own device.
What It Actually Does
Nine Defenses, Not One List.
Alongside the filter lists, MachOne runs nine named defenses — the same nine the app lists.
