## What is Shieldio?

Shieldio blocks ads, trackers, cookie notices and other annoyances in Safari on iPhone and iPad. Pages load faster, look cleaner and follow you around less.

TURN IT ON ONCE
Shieldio works through Safari's built-in content blocking, so you turn it on once in Settings: go to Settings > Apps > Safari > Extensions, open Shieldio's three extensions (Ads, Trackers and Annoyances), and turn on Allow Extension for each. Shieldio walks you through this on first launch and checks each step for you. On iOS 26.2 and later, one button takes you straight to the right screen.

CHOOSE WHAT TO BLOCK
• Ads: banners, sponsored boxes and requests to ad networks
• Trackers: analytics scripts, tracking pixels and other data collectors that follow you from site to site
• Cookie Notices: cookie and consent banners are hidden
• Annoyances: newsletter and notification pop-ups, app banners and other page clutter
• Social Widgets (off unless you turn it on): like and share buttons and embedded social media posts

PRIVATE BY DESIGN
• Safari applies Shieldio's rules itself. Shieldio can't see the pages you visit or anything you type on them.
• No account, no analytics, no ads, no tracking. Data Not Collected.
• Filter lists update automatically, straight from the people who maintain them, over a secure connection. The requests carry no identifiers and none of your settings. Turn Automatic Updates off and Shieldio stops making network requests unless you ask it to check.
• Works offline from the first launch: a recent copy of every list comes with the app.

STAYS OUT OF THE WAY
• No VPN and no configuration profile. Blocking happens inside Safari.
• If a site misbehaves, turn blocking off for just that site with Safari's own controls. Shieldio's Help shows you how.
• Report a broken site by email from inside the app.

GOOD TO KNOW
• Shieldio works in Safari and in web pages that other apps open with Safari's built-in viewer.
• It can't block ads in other browsers, in apps' own built-in browsers or inside other apps, and it can't block video ads on YouTube.
• Some sites notice ad blockers and ask you to turn them off.
• Requires iOS 18 or later.

FILTER LISTS
Most of Shieldio's rules come from EasyList, EasyPrivacy and Fanboy's Annoyance, Cookie and Social lists, written by the volunteers of the EasyList project (easylist.to) and used under their Creative Commons licenses. The list authors aren't affiliated with Shieldio and don't endorse it. Full credits: https://jawny.github.io/shieldio/acknowledgements.html
