About Control D

Control D offers a free public DNS service that can block ads, trackers, malware and other sites on devices that are configured to use it. Users choose a ready-made protection level, such as Malware Protection, Ads & Tracking, Social, or Family Friendly, or build a custom set of filters. The homepage says the service works without installing an app.

The service supports encrypted DNS protocols, including DNS-over-HTTPS/3 and DNS-over-TLS. Control D states that it does not store individual browsing history, timestamps, or logs, and that it does not use third-party tracking on its website. Privacy practices are described in its privacy policy, and the source does not establish how this applies to every configuration. Some filter options are listed under Premium Filters, and a Buy Premium option is shown, but the source does not list which features require a paid plan.
