A tracker is a piece of software used to exchange information about your actions online with third-party companies. Their use can slow down Internet browsing, consume your network cap, waste your battery and expose your private data to advertisers, cyber criminals and governments.

NextDNS can block most trackers when the Ads & Tracker blocklist is enabled. All NextDNS blocklists are gathered from well known public sources, refreshed hourly and available on our Github.
