After many requests from our users, the new and noteworthy Tracker Radar by DuckDuckGo is now available in Blokada! Credits: the [Tracker Radar](https://github.com/duckduckgo/tracker-radar) database is licensed by DuckDuckGo under the [CCBY-NC-ND 4.0 license](https://github.com/duckduckgo/tracker-radar/blob/master/LICENSE). [Learn more about the available blocklists here](https://community.blokada.org/tag/blocklist). ### How to use it? Please note, despite the best effort to avoid any incompatibilities, this is an early preview, **and it may break some of sites you visit, or apps you use**. In order to activate it on Android (Blokada 5): - Open “Advanced” tab - Tap “Blocklists” - Find “Duck Duck Go” at the bottom, and activate it In order to activate it on Android (Blokada 4): - Go to bottom `menu -> adblocking -> host lists`, - Activate the list, - It may take some time before the new list reaches your device. To speed it up, go to `bottom menu -> adblocking -> adblocking settings`, and tap `Sync` in list download settings. In order to activate it on iOS: - Update to Blokada 5.0.4 or newer, - Go to `Advanced` tab, then tap `All`, - Find the feature on the list and activate it. ### How is it made? Considering the data model of the Tracker Radar, generating a verbatim list of hosts would not work well and cause many issues for host list based content blockers, like Blokada. Instead, we have developed [a script](https://github.com/blokadaorg/landing-github-pages/blob/master/scripts/ddg.py) that generates the blocklist in a bit different way. First of all, it will generate hosts with subdomains (and not top level domains), and will not include entries for very common subdomains, like `www` or `api`, that could easily break things. Second, it will only include entries for domains, for which the Tracker Radar detected enough of tracking resources for that subdomain. This, again, helps to eliminate entries that could break things. And finally, some categories, like CDN or Online Payment, are also ignored and not included in the list. With this approach, we decided to err on the side of caution. Currently, the final list includes over 3k hosts, which seem to nicely compliment the more common blocklists. We will adapt the script based on your feedback, so feel free to comment on this article! ---

Thanks for the great work! If anyone is facing problems with the images in wikipedia and the enabled DDG Tracker Radar List at the moment you’ll need to allow the domain _[upload.wikimedia.org](http://upload.wikimedia.org)_.

This lists blocks [store.steampowered.com](http://store.steampowered.com) and thus breaks the Steam App Somehow allowing the domain withing Blokada doesn’t help, it still gets blocked. Only deactivating Blokada helps. ---

FYI, images for all items listed on eBay started getting blocked. I think it’s the latest DuckDuckGo Tracker Radar host list. The list dated Feb 26, 2021, has [I.ebayimg.com](http://I.ebayimg.com) in two spots. When I turn that list off, I get the eBay pictures back in both Android eBay app and browser. ![Screenshot_20210228-010019_Chrome](https://europe1.discourse-cdn.com/flex017/uploads/blokada/original/2X/c/cbe7336210868993dbcc06973023f86c4d9f4476.jpeg) ---

`menu-static.gog-statics.com` is the static images for the menu of [GOG.com](http://GOG.com) This breaks [gog.com](http://gog.com) when browsing from a mobile device. `login.msa.msidentity.com` is a microsoft login website used for authentication purposes and is blocked by this list Also I seem to be limited to only 6 posts so I will move future whitelisting requests to your GitHub. ---

@Karol, two items: 1. This lists prevents me from logging into `indeed.com`. We need to allowlist `newassets.hcaptcha.com^`. Also need to allow `jsv3.recruitics.com^` as I can’t navigate to a job site without this list blocking the page load. Here’s a [link](https://www.indeed.com/viewjob?jk=2393b7f9170ab516&vjs=3) to a sample job if you wan to try to replicate my issues. 2. How often are we updating this list from the Duckduckgo Tracker Radar and filtering it through our allowlist? For instance, [this project](https://gitlab.com/curben/tracking-filter#tracking-js-blocklist) uses DuckDuckGo’s Tracker Radar and their blocklist is updated on the first day of the month. However, unlike ours, their list contains **all** the links that Tracker Radar detected to have browser fingerprinting; there is no further processing to remove false positive.
