What do we classify as personal information?

The purpose of data protection is to protect personal information. Personal information means 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, location data, an identification number, 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. This information also includes information in connection with payments.

The information Ad Block Zen collects

Anonymous information

The Ad Block Zen extension captures anonymous usage information including, but not limited to, the version number of the extension, acceptable Ads opt-in, preferred language, opt-in to advanced features like our local content caching service, number of ads blocked, number of blocked requests, browser and operating system type. The Ad Block Zen extension also assigns an anonymous, unique ID to each installation. We store aggregate statistics about the installation connected with each user ID indefinitely. We utilize this information to help us identify and fix potential issues with Ad Block Zen as well as to determine the performance of Ad Block Zen features.

Personal information

When you visit the Ad Block Zen website we collect IP address, unique ID, logging of some of the button clicks on our website (clicking download or install for example) and user event logging data. When the Ad Block Zen extension communicates with our servers, we receive the computer’s IP address. After six months we will remove any identifying information such as IP address from our log files and databases.

Extension error information

An error report is sent automatically to Ad Block Zen's servers when an error occurs in the extension. The report contains the anonymous information stated above together with the current browser version and a description of the error. If a URL exists in the error description then the extension will attempt to remove it. The data is used for troubleshooting and to identify general defects which lead to unexpected crashes or errors. We remove this information after 7 days from our log files and databases.

Server logs

For up to 90 days, we keep logs for general requests made to or its infrastructure. These logs include the IP address, browser, operating system, and page address. We anonymize the IP address by using a hash to encrypt this information and we immediately delete the original IP address. This data is used to generate usage statistics and to investigate potential security problems. After 90 days, we will remove this information from our log files and databases.

Logs for payment processing requests are kept, in accordance with US tax law retention periods and will be deleted after the end of the respective retention period. Information in such logs includes IP address, email (if provided), address (if provided), name (if provided), browser type and version, operating system, payment amount, payment type, card type, expiration date, and last four digits of the card if a card is used. This data is used to provide insights into the financial performance of Ad Block Zen.
