Hosts Ad Blocking

A hosts-rule ad blocker with cosmetic filtering. Open it from ⋮ → Hosts Ad Blocking.

Features

• Active rules count — see how many blocking rules are loaded.
• Sources — manage filter subscriptions: download, import from a file or URL, or delete a source. Custom imports get a display name and render as their own cards with enable/disable/delete.
• Built-in lists — 20 community filter lists (EasyList, uBlock Origin, AdGuard, AdAway, plus 8 language-specific lists).
• Search — find specific rules.
• Clear — remove all loaded rules (with confirmation).

Cosmetic filtering

Beyond host blocking, a MutationObserver-based cosmetic filter hides elements matched by cosmetic rules.

Notes

• Ad blocking is wired for both preview and export: the host blocker serves preview, and the compiled rule set ships inside the generated APK.
• Configure ad blocking per app under Privacy — the per-app subscription selector offers the built-in lists and your imported custom sources.
