Frequently asked questions
Does AdBlocker Ultimate have a free plan+
Yes. The model is listed as free, so browser blocking starts without charge. Paid app cover is separate for system wide blocking, so check which placement matches the devices used for daily browsing.
What are the limits of the free version+
Limits are described as Free browser extension; paid app for system-wide blocking. That means browser extension use is free, while full system wide blocking sits in the paid app. Readers who only need browser cover can stay free, while wider cover needs the paid tier.
Which platforms and browsers are supported+
Supported places include Windows, macOS and Android. That spread covers desktop systems, mobile systems and major browsers. Readers can keep the same blocker across home and mobile browsing without changing tools for each browser.
Does it support private DNS protocols+
On supported Android builds the protocols include doh, dot and dnscrypt. Those options relate to private DNS handling alongside blocking. Readers who care about DNS privacy should confirm support on the exact app build before relying on it.
What is the logging policy+
The stated approach is No excess data collection. That wording points toward limited collection rather than detailed retention claims. Readers with sensitive needs should read the full policy and browser permissions before treating the claim as a full privacy guarantee.
How can users get support+
Help runs through email and help centre. That gives written help and self serve guides for setup and billing questions. Readers who prefer direct calls or live chat should weigh that route before choosing the paid app.
