AdZero: Clean, Ad-Free Web

Block Safari ads, popups, and trackers without an account or subscription. Includes regional filters and optional encrypted DNS protection.

Malicious advertising is the primary cause of personal data leaks and data waste. Are you concerned by the sudden ads and unsolicited pop-ups that appear while using Safari?

AdZero is a Safari content blocker for iPhone and iPad with no account or subscription required. Five focused blocker categories—Ads, Privacy, Korean Sites, Annoyances, and Custom Rules—work with a Safari helper to reduce banners, popups, tracking scripts, cookie notices, and other distractions.

KEY FEATURES • Block Safari ads and popups • Reduce web trackers and analytics scripts • Regional filtering tuned for Korean websites • Hide cookie notices, subscription prompts, and other annoyances • Manage per-site allowlists and custom blocking rules • Download current filters without waiting for an app update • Optional encrypted DNS presets from established public providers • Diagnose protection status and report site issues

PRIVACY AdZero does not send visited website addresses, search terms, or browsing history to AdZero servers. Settings and blocking statistics remain on your device. Filter updates download rules from a GitHub CDN. When you enable DNS protection, DNS queries are encrypted and sent to the public DNS provider you select. AdZero cannot view or store those queries, but the provider’s privacy policy applies and it may process limited de-identified operational logs.

BEFORE YOU START • Safari protection works after you enable the AdZero extensions in iOS Settings. The app includes step-by-step guidance. • Encrypted DNS uses the iOS system DNS setting; it is not a VPN. • Websites and advertising technology change continuously. Use Filter Update to apply the latest available rules.

If a site is not blocked correctly, use the in-app report feature so it can be investigated.
