Piwik.org Privacy Policy explains how Piwik.org gathers and uses Users data when they visit Piwik.org. Learn more about Web Analytics & Privacy.

Website Visitors

Like most website operators, Piwik.org collects non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request. Piwik.org’s purpose in collecting non-personally identifying information is to better understand how Piwik.org’s visitors use its website. From time to time, Piwik.org may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in the usage of its website.

Piwik.org also collects potentially personally-identifying information like Internet Protocol (IP) addresses. Piwik.org does not use such information to identify its visitors, however, and does not disclose such information, other than under the same circumstances that it uses and discloses personally-identifying information, as described below.

Gathering of Personally-Identifying Information

Certain visitors to Piwik.org’s websites choose to interact with Piwik.org in ways that require Piwik.org to gather personally-identifying information. The amount and type of information that Piwik.org gathers depends on the nature of the interaction. For example, we ask visitors who use our forums to provide a username and email address. In each case, Piwik.org collects such information only as is necessary or appropriate to fulfill the purpose of the visitor’s interaction with Piwik.org. Piwik.org does not disclose personally-identifying information other than as described below. And visitors can always refuse to supply personally-identifying information, with the caveat that it may prevent them from engaging in certain website-related activities.

Protection of Certain Personally-Identifying Information

Piwik.org will not rent or sell potentially personally-identifying and personally-identifying information to anyone.

If you are a registered user of a Piwik.org newsletter and have supplied your email address, Piwik.org may occasionally send you an email to tell you about new features, solicit your feedback, or just keep you up to date with what’s going on with Piwik.org and our products. We primarily use our blog to communicate this type of information, so we expect to keep this type of email to a minimum.

Piwik.org takes all measures reasonably necessary to protect against the unauthorized access, use, alteration, or destruction of potentially personally-identifying and personally-identifying information.

Aggregated Statistics

Piwik.org may collect statistics about the behavior of visitors to its websites. For instance, Piwik.org may reveal how many downloads a particular version got, or say which versions are most popular based on checks from api.piwik.org, a web service used by Piwik installations to check for new versions of Piwik.


A cookie is a string of information that a website stores on a visitor’s computer, and that the visitor’s browser provides to the website each time the visitor returns. Piwik.org uses cookies to help Piwik.org identify and track visitors, their usage of Piwik.org website, and their website access preferences. Piwik.org visitors who do not wish to have cookies placed on their computers should set their browsers to refuse cookies before using Piwik.org’s websites, with the drawback that certain features of Piwik.org’s websites may not function properly without the aid of cookies.

Although most changes are likely to be minor, Piwik.org may change its Privacy Policy from time to time, and in Piwik.org’s sole discretion. Piwik.org encourages visitors to frequently check this page for any changes to its Privacy Policy. Your continued use of this site after any change in this Privacy Policy will constitute your acceptance of such change.
