Keynote: We do not share or sell any of your personal data. We are proud to say that we fight for users' privacy and we are strongly committed to this principle and to being as transparent as possible.
We believe that privacy is a fundamental human right. That's why we are transparent about what AdGuard does, and explain the purpose of every little bit of information that may be gathered by our apps and services.
Below we list all the information that we may collect via AdGuard DNS and explain why we do it and how we use this information. The information we collect includes no more than is crucial to provide the full functionality of AdGuard DNS, both public and private. We do not collect anything for tracking purposes and take all necessary measures to protect the information we get.
Who We Are
ADGUARD SOFTWARE LIMITED is a company registered in Nicosia, Cyprus, registered office is at Klimentos 41-43, KLIMENTOS TOWER, Flat/Office 25, 1061, Nicosia, Cyprus and acts as the data controller when processing your data.
What We Do
AdGuard DNS operates as a DNS resolver which can block access to certain domains, depending on the chosen configuration (server):
AdGuard DNS Default blocks access to domains that we consider ad, tracking, or malware. This list is constantly updated based on the community feedback.
AdGuard DNS Family blocks access to the same domains as Default, and also to domains that may contain adult content. It also enforces safe search and other safe modes wherever possible, which can result in modified search results, missing comment sections, and other differences in web page appearance compared to its original state.
Non-filtering AdGuard DNS doesn't block or redirect anything. It only returns the IP address of the requested domain.
Private AdGuard DNS blocks DNS queries or modifies DNS responses in accordance with the user’s preferences. In addition to that, it displays the queries and statistics to the user via the AdGuard DNS dashboard. Registering an AdGuard account is required to use this type of DNS resolver.
Whenever an AdGuard DNS server (except non-filtering servers) receives a request to a domain that’s considered to be an ad or tracking domain, it returns an “unspecified IP” response (
0.0.0.0). Whenever an AdGuard DNS server (except non-filtering servers) receives a request to a domain that’s considered to be a malware domain, or when an AdGuard DNS Family server receives a request to a domain that’s considered to be an adult domain, it replies with a redirect to a dummy page that explains what has happened.
If you disagree with us about classifying a certain domain as advertising, tracking, malicious, or adult one, or if you believe a certain domain should get blocked by one of AdGuard DNS servers, contact us at email@example.com.
What Data AdGuard DNS Can Collect And When
We do not collect anything about the user specifically. In other words, your IP address or any data about you is not logged.
We store aggregated performance metrics of our DNS servers, namely the number of complete requests to a particular server, the number of blocked requests, and the speed of processing requests.
We keep and store the anonymous database of domains requested in the last 24 hours. There is no information whatsoever that could link any of these domain names to the original user who sent the request. We need this information to identify and block new trackers and threats.
We also log how many times this or that tracker has been blocked. We need this information to remove outdated rules from our filters.
All data that we collect is not shared with any third parties. It is used solely for internal purposes such as performance analytics. The only information that we can possibly share is derivatives, i.e. lists of domains that our servers recognized as advertising, tracking, or malicious.

In this case, AdGuard DNS will block DNS queries or modify them according to the user’s preferences.

We store the log of your DNS queries in order to display it to you on the AdGuard DNS dashboard. The users may opt to disable logging via the account settings. The log is only stored for a limited period of time which can also be configured via the account settings.
How We Use Your Personal Data
We follow EU’s General Data Protection Regulation (“GDPR”) which defines personal data the following way:
…any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
When we use terms “personal data" or “personal information”, we mean exactly that.
We retain Personal Data for as long as necessary to continue providing you with our products and services, or until you revoke your consent to share this information.
You have the following rights when it comes to Personal Data:
Export all Personal Data that we hold about you to a local file from your AdGuard Account;

We make every possible effort to protect you and your Personal Data from unauthorized access, alteration, disclosure or destruction. We implement and maintain the following technical and security measures:
System Access Controls: We take reasonable measures to prevent Personal Data from being used without authorization. These controls shall vary based on the nature of the processing undertaken and may include, among other controls, authentication via passwords and/or two-factor authentication, documented authorization processes, documented change management processes and/or logging of access on several levels.
Data Access Controls: We take reasonable measures to ensure that Personal Data is accessible and manageable only by properly authorized staff. Direct database query access is restricted and application access rights are established and enforced to ensure that persons entitled to use a data processing system only have access to the Personal Data to which they have privilege of access; and that personal data cannot be read, copied, modified or removed without authorization in the course of processing.
Storing Data in a Data Center: personal information is stored in a data center located in Frankfurt. This is secure: the data center does not demand that we collect any data about your traffic or your use of our products and services. If they request us to start doing so, we will stop working with this provider and find an alternative.
Transmission Controls: We take reasonable measures to ensure that it is possible to check and establish to which entities the transfer of personal data by means of data transmission facilities is envisaged so personal data cannot be read, copied, modified or removed without authorization during electronic transmission or transport.
Input Controls: We take reasonable measures to make it possible to check and establish whether and by whom personal data has been entered into data processing systems, modified or removed.
Data Backup: Back-ups of the databases are made on a regular basis, they are secured and encrypted to ensure that personal data is protected against accidental destruction or loss when hosted by us.
