Does it work with every app, not just the browser?

Yes. By filtering at the DNS level, it blocks ads and trackers in every app on the phone, including games with interstitial and rewarded videos.

Does it slow down the connection or drain the battery?

No. Only DNS traffic is routed to the app; the rest of your connection goes out over the normal network untouched. Blocking prevents ad downloads, so you often browse faster and use less data.

DNS blocker · 100% local

Goodbye ads across your whole Android

MegaDBlock blocks ads, videos that pop up mid-game, trackers and cookie banners in every app — with a local VPN that never sends your traffic to any server.

Real privacy, not marketing

Your traffic never goes to a server of ours

MegaDBlock spins up a local VPN inside your own phone. It intercepts only DNS queries and decides what to block instantly. There's no cloud, no proxy, no log of what you visit. The only thing it downloads from the internet is the block lists — domains from megadblock.com/domains.txt and regular expressions from megadblock.com/regex.txt — simple text files it fetches once on first launch, and again only when you tap update.

Features

A full blocker, not just for the browser

By filtering system-wide DNS, MegaDBlock works in every installed app — games included.

DNS blocking

Every query is matched against the list; if it's advertising or tracking, it's answered with 0.0.0.0 without leaving the network. Everything else is untouched.

Game ads

Stops the interstitial and rewarded videos that interrupt your matches: AppLovin, Unity Ads, ironSource, Vungle, AdColony, Chartboost and more.

Live log

Watch every queried domain in real time, which app requested it, and whether it was blocked or let through — with filters by status.

Per-app attribution

See which app makes each request, with its name and icon, thanks to the system API (Android 10+). You'll know exactly who's tracking you.

Regex rules

Block any host that matches a regular expression. A live preview shows you exactly which domains will fall before you commit the rule.

Cookie banners

Silence consent pop-ups by blocking 78 CMP services (OneTrust, Cookiebot, Quantcast, Didomi) without breaking the websites.

What it blocks

The networks that serve you ads and videos

MegaDBlock ships preconfigured against the major ad-mediation and video networks used by apps and games:

Plus analytics, telemetry and ad-profiling trackers — all from the megadblock.com/domains.txt and megadblock.com/regex.txt lists, which you can update with a single tap.

Frequently asked questions

What people ask

Does MegaDBlock send my data to any server?

No. It creates a local VPN on your own device; your traffic never passes through any server of ours, and nothing is logged. The only thing it downloads from the network is the block lists from megadblock.com/domains.txt and megadblock.com/regex.txt — fetched once on first launch, and again only when you tap update.

Does it need root access?

No. It uses Android's standard VpnService API, with no root and no special system permissions.

Does it work in all apps or just the browser?

In all of them. Because it filters at the DNS level, it blocks ads and trackers in any app on the phone, including games with interstitial and rewarded videos.

Does it slow the connection or drain the battery?

Not noticeably. Only DNS traffic is routed to the app; the rest goes out over the normal network untouched. By avoiding ad downloads, you often browse faster and with less data.

What exactly does it download from megadblock.com?

Only a text file with the domains and keywords to block. No personal data ever leaves your device at any point.

Can I add or remove rules?

Yes. In the Domains tab you block or allow specific hosts and create regular-expression rules, with a preview before applying them.
