PubBlock: Ad & Tracker Blocker

PubBlock cleans up Safari and your apps: no more banners, no more pop-up ads, no more trackers following you from site to site. Pages load faster, use less data and respect your privacy.

HOW IT WORKS
• Safari content blocker (free): PubBlock hands Safari a compiled rule list, and Safari blocks ads and trackers before they even load. No injected scripts, nothing read from your pages.
• Safari extension for youtube.com (free): it removes the site's video ads, including the ones that play before the video, sponsored Shorts and promoted videos in the feed.
• Blocking in all your apps (Pro, iOS 26 or later): PubBlock's own encrypted DNS server gives no address to known advertising and tracking domains, so they never load, whatever the app. You select it once in Settings > General > VPN & Device Management > DNS, and PubBlock checks that it really works.

WHAT MAKES PUBBLOCK DIFFERENT
• No data collection: no account, no analytics. The Safari blocker runs entirely on your iPhone or iPad, and PubBlock's DNS server keeps no logs.
• No subscription: PubBlock Pro is a one-time purchase.
• A list built for the French-speaking web: on top of the big global ad networks, PubBlock blocks the French and European ad-tech and tracking tools that generic lists often miss.
• Your own rules: allow the websites you choose in Safari, and add your own blocked domains.
• An honest status: the home screen says exactly what is protected right now, and why when something is off.
• Light and quiet: no complicated settings, everything works in the background.

KNOWN LIMITATIONS
• Ads served from the same domain as the content cannot be blocked by a domain filter: that is a limit of the technique, not an oversight. Video ads inside the YouTube app therefore remain impossible to block; on youtube.com in Safari, the extension handles them.
• While a VPN is connected, iOS sends DNS through the VPN, so blocking in your apps pauses; the Safari blocker keeps working.
• Some sites show empty spaces where blocked ads used to be.

PUBBLOCK PRO
One-time purchase, no subscription: blocking in all your apps (iOS 26 or later) plus your own blocked domains. The Safari blocker and the YouTube extension stay free, forever.
