Overview
How does blockerDNS work?
Once signed up, just copy/paste your unique DNS URL into your Android phone's Private DNS setting as shown below, and you're all set! You will have gotten an email with your URL, and you can always sign in to see your URL as well.

What is DNS?
Cloudflare's website has a great explanation. To quote them, "The Domain Name Systems (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

"Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4)."

What is blockerDNS?
blockerDNS is a DNS service that works just like any other DNS service, translating your google.com request to something like 172.217.10.46 or 172.217.10.14. (You can copy/paste either one into your browser to see how it takes you to google.com.)

blockerDNS has one major difference though. When you visit a website and it requests the IP address for the domain that serves up their ads, and for the other domain that tracks you all around the internet, rather than fetching the IP addresses, blockerDNS instead replies that it doesn't know them. (Actually that's not true, it's slightly more technical but you don't need to worry about that. But if you want to know, read the next paragraph.)

For all blocked domains, blockerDNS reports the IP address as 127.0.0.1, which points back to the device you're using. It's called the loopback address and for any device you're using it always points to itself. Except your phone obviously isn't serving up ads from itself, so when web sites try to load their ads, well... they just don't load. If you want to read more about the loopback thing, you can check out the Wikipedia article.

How is blockerDNS different from ad-blocking apps or VPNs?
Ultimately, you get the same end-result: no ads. But with the apps you're adding extra layers of overhead. Typically, ad-blocking apps are actually an entirely separate browser with its DNS settings altered, and you're stuck using that alternate browser instead of what you actually prefer, like Chrome or Firefox. Other services involve VPN connections or proxies that slow down your whole experience and are just a whole separate headache.

With blockerDNS you aren't installing anything. You're simply pointing your phone to our DNS service instead of the default, which is usually provided by your wireless carrier. Your internet speed doesn't get bogged down - in fact, it'll probably seem faster because you won't be loading megabytes on top of megabytes of annoying ads.

Can I use blockerDNS on any phone?
Unfortunately, no.

You need an Android phone running Android version 9 (Pie) or higher. The way we're able to block ads without you installing an app is by taking advantage of an Android setting introduced by Google in 2018 with the release of Pie. If you don't see your version automatically detected below, you can check it manually by going to Settings, followed by the About Phone section.

Do I get a username and/or password to use blockerDNS? How do you know I'm actually a user if all I'm doing is putting in a DNS server in my settings?
The way we handle authentication is by giving you a unique URL to put as your setting. It'll be something like asdfghjkl.blockerdns.com. The first portion is what serves as your "username".

Do you log my DNS requests and track my browsing history?
NO.

There is ZERO logging of DNS requests. The ONE thing we keep basic track of is how often your phone pings our servers, solely for the purpose of preventing abuse. And by abuse we mean if you decide to share your unique URL with the entire internet. That said, a reasonable amount of sharing is OK. Go ahead and give your mom your URL if you want.

Is my data at risk if you have a security breach?
It goes without saying that security is taken very seriously. We know that's what everyone says, but please read on.

The only information we store about you is your email address, and the randomly generated unique username that's assigned to you for the custom URL that you would be entering into your phone's "Private DNS" setting. That's it for us!

We can't lose your private data if we don't have it to begin with!

Regarding third-parties we deal with, our payment processor is Stripe, and their checkout process asks you for the basics needed to charge your credit card. They will ask you for the following: email, credit card, name on card, country/region and ZIP code. Even once you are subscribed, we do not retrieve and store any additional information about you. You can read Stripe's privacy policy here.

What if I don't have a setting on my phone for Private DNS?
You need an Android phone running Android version 9 (Pie) or higher. The way we're able to block ads without you installing an app is by taking advantage of an Android setting introduced by Google in 2018 with the release of Pie. If you don't see your version automatically detected below, you can check it manually by going to Settings, followed by the About Phone section. If your phone doesn't support Private DNS and you already signed up, just email us at support@blockerdns.com to cancel.

{{checkAndroidVersion()}}

What if I'm still seeing some ads?
Our database of blocked domains is actively maintained so, by all means, please let us know at support@blockerdns.com. Be sure to include the website or app where you saw the ad. The more information you can provide, the better.

What if blockerDNS breaks a website or app that I use?
Our database of blocked domains is actively maintained, though possibly a bit too zealously at times. While we try to minimize breaking sites, apps and services, we may sometimes end up adding a domain to our block list that is required for a specific site or app to function properly. If you come across a site or app that doesn't seem to be loading correctly, is giving you error messages, or is just acting strange, please let us know at support@blockerdns.com. We'll take a look and if in fact it does turn out to be caused by us blocking something we shouldn't, we'll fix it ASAP.

Fixes like this are often done within minutes, but if you need to use the site or app in question urgently you can temporarily turn off the Private DNS setting.

How do I cancel my subscription?
You can sign in here on the website and you'll be given the option to cancel. If you prefer, you can also contact us at support@blockerdns.com.

About
blockerDNS is a modest one-man operation run by me, Tambe Barsbay. It grew out of an ad blocking DNS-over-TLS system that I set up for myself when Google introduced the Private DNS setting in Android 9. For a few years I'd been running my own DNS servers for ad blocking on my home network, which of course covered my phone. But to get my (unrooted) phone to use my own DNS servers when I wasn't home, I had to resort to running a VPN server that pushed my DNS settings to the phone. That way I'd get my ad blocking while using mobile data or any other WiFi.

But I was always annoyed at the extra overhead and inevitably slower speeds from a VPN. So when Android got the user-customizable Private DNS setting I immediately got to work on figuring out the whole DNS-over-TLS thing and before long I was up and running. Blocking ads phone-wide by changing one single setting was so easy and elegant that I quickly found myself telling anyone I knew with Android to set their DNS to my servers.

One thing led to another, and eventually blockerDNS was born.

blockerDNS is based in the U.S. and its infrastructure is hosted on Google Cloud Platform and DigitalOcean.

My personal site is tambeb.com.
Thank You!

Terms of Service
Created July 16, 2019. This is a work in progress as we only very recently launched.

Allowed Usage / Sharing
We keep basic track of how often our servers are pinged through users' unique URLs, logging only the unique randomly generated usernames (the string prepended to '.blockerdns.com') and a timestamp. We do this for the purpose of preventing abuse, with abuse being defined as the user freely disseminating their unique URL so that others may use our service without subscribing legitimately. Abuse of our service will be assumed if the frequency of communication with our server is significantly higher than one would typically expect for a user.

Having said that, we would not consider it abuse for a user to share their URL with a friend and/or family member or two.

Subscriptions
Monthly subscriptions can be canceled at any time, with a user's service remaining active and usable for the remainder of their billing period. There are no prorated refunds.

Privacy Policy

Privacy Information
Created July 12, 2019. This is a work in progress as we only very recently launched.

Privacy is important! In fact, one of the primary purposes of blockerDNS is to increase privacy while browsing the internet. blockerDNS was created and is run by Tambe Barsbay (Company, we, us or our) from New Jersey in the United States. If you have any questions please contact us at support@blockerdns.com.

Information we collect
We analyze traffic to our web site using Google Analytics. Google Analytics uses cookies to track non-personally identifiable information about visitors in aggregate form. (We would note that blockerDNS actually blocks Google Analytics, along with many other tracking services, for users of our service. As a result, they would not be trackable by services like Google Analytics, even on our own web site.)

To sign up for our service, users must log in with their Google account, from which we access and store the user's email address. That email address is the only personal information we store about our users. We chose to do a Google account login, as opposed to maintaining our own login system where we keep usernames and passwords ourselves, to minimize the amount of personal user information that we need to store. To put it simply, we cannot lose users' sensitive private data if we do not have it to begin with.

Our payment processor is Stripe, and their checkout process asks users for the basics needed to charge their credit card. They ask for the following: email, credit card, name on card, country/region and ZIP code. Even once a user is subscribed, we do not retrieve or store any additional information. Stripe's privacy policy can be found here.

For users of our service, we do not log DNS requests. We only keep basic track of how often a user's mobile phone pings our servers, logging only their randomly generated unique username (prepended to '.blockerdns.com') and a timestamp. We do not log or access their IP address or any other information. We log these pings solely for the purpose of preventing abuse, with abuse being defined as the user freely disseminating their unique URL so that others may use our service without subscribing legitimately. Abuse of our service will be assumed if the frequency of communication with our server is very significantly higher than one would expect for a user.

Use of information
As mentioned above, the only private user data we store is the user's email address. The email address is associated with a randomly generated string of letters that we prepend to ".blockerdns.com" to serve as their unique, personal URL that is used to access our service. Additionally, we will use this email address to contact the user regarding their service with blockerDNS. We may also use the email address to request feedback about the quality of our service from users. User emails will never be sold or otherwise provided to any third-party and will never be used for marketing.

To reiterate from above, we keep basic track of how often a user's mobile phone pings our servers, logging only their unique randomly generated username (prepended to '.blockerdns.com') and a timestamp.

As described above, we use Google Analytics to monitor the traffic to our web site. Google Analytics is unable to track users of our service, as we block them. But visitors to our web site that are not users may read Google's privacy information here.

Sharing of information
As mentioned above, user emails, the only private data we store, will never be sold or otherwise provided to any third-party.

Security
It goes without saying that security is taken very seriously. We know that this what everyone says, but please read on.

To sign up for our service, you must log in with your Google account, from which we access and store your email address. That email address is the only personal information we store about you. We chose to do a Google account login, as opposed to maintaining our own login system where we keep usernames and passwords ourselves, to minimize the amount of personal user information that we need to store. To put it simply, we cannot lose your sensitive private data if we do not have it to begin with.

Your choices
As an active user there is no data that a user can request to be deleted. We only store the user's email and that is needed to provide our service. An inactive user may request that we delete their email address from our database since they are no longer using our service by emailing us at support@blockerdns.com. However, it should be noted that the email address used to submit the request, along with the email address to be deleted as noted in the email body - if it is different, will remain archived in our email storage as with all emails. Our email is hosted with Google's G Suite service.

As a non-user, you may opt out of Google Analytics data collection by using a browser extension provided by Google. As a user of our service this is unnecessary as we block Google Analytics as part of our ad and tracker blocking.

Cookies
blockerDNS itself does not use cookies on our web site. However, cookies are used by the three third-party tools used on our web site: Google Sign-In, Google Analytics and Stripe.

Press Release
blockerDNS Launched for Android, Offering Easy Ad Blocking with No App, VPNs or Proxies Required

by Tambe Barsbay
July 24, 2019

NJ, USA

blockerDNS ( blockerdns.com ) has launched a unique new ad blocking service for Android users. The new service takes advantage of the Private DNS feature introduced in Android 9 to give users full ad blocking without requiring the installation of an app or the use of a VPN or proxy. Users instead receive a unique URL which they then set as their Private DNS provider in Android’s network settings. With this easy one-step setup users can enjoy ad and online tracker blocking for everything from browsing the internet with whatever browser they choose, to catching up on the news with their favorite app, to anything else. And best of all, blockerDNS works for both WiFi and mobile internet.

blockerDNS’s primary mission is privacy online. And to that effect, there is ZERO logging of DNS requests. In addition, outside of the basics needed for setting up a monthly subscription with our payment processor Stripe, there is NO other collection of any personal user data. We don’t even maintain our own username and password database and instead have users log in with their Google account, from which we simply access their email address for basic account communication. With consumers increasingly focusing on their internet privacy and the collection of their data, blockerDNS is the absolute easiest way to clamp down on online tracking by marketers and ad networks.

About blockerDNS

Based in the US, blockerDNS is a modest one-man operation that grew out of an ad blocking DNS-over-TLS system set up by the owner, Tambe Barsbay, for personal use after growing frustration with other methods that involved VPNs or proxies or extra overhead in the form of apps that were essentially alternative browsers. All aspects of the service, from the TLS tunneling of DNS requests, to the user authentication system (detailed below), to the constantly maintained and updated blocking database, were developed by the owner.

DNS-over-TLS, the protocol behind Android’s new Private DNS feature, inherently has no user authentication mechanism. blockerDNS’s creative solution to this is that, after signing up, users are given a unique URL to be entered into Android’s Private DNS setting, with the first part of the URL serving as their username. For example, a user may get the URL asdfjkl.blockerdns.com, with “asdfjkl” being their user id. blockerDNS only responds to requests made through valid URLs. Requests through URLs with invalid user ids are simply dropped and will not work.
