• Help us to improve Piwik by sending anonymous usage data (and get usage data yourself)

  22 octobre 2015, par Thomas Steur — Community, Plugins

  At Piwik we have developed a new plugin named AnonymousPiwikUsageMeasurement. The opt-in and anonymised usage tracking information will be used by us to build a better product and a great user experience. The plugin can be installed via the Piwik Marketplace with just a few clicks in your Piwik installation. As a Super User simply go to the Administration and select Marketplace in the left menu. There you will find the plugin and can install it with just one click.

  The plugin allows you to track usage data into up to three Piwik installations :

  • demo-anonymous.piwik.org (enabled by default, can be disabled).
  • your own Piwik (can be configured optionally)
  • a custom Piwik (can be configured optionally)

  The usage data that is sent to Piwik can be publicly viewed by anyone under demo-anonymous.piwik.org.

  What are the advantages by tracking the data into my own installation ?

  You can see how your Piwik installation is used and how well your Piwik performs by checking the average generation time of pages and API calls. Use the Row Evolution feature to see how your Piwik is performing over time.

  What is Piwik doing to make sure the data is anonymized ?

  We are very careful in what we track and we make sure to anonymize data that could contain user data.

  • We overwrite the page title as the title could contain the name of the viewed website
  • We remove any referrer information
  • We replace URL paramaters with a predefined value apart from a few whitelisted ones to make sure no actual token_auth, CSRF token or user defined value will be tracked
  • On demo-anonymous.piwik.org 3 bytes of the IP are anonymised (eg when IP is 192.168.1.1 we track only 192.0.0.0). We do not track nor collect your location and provider information.
  • We do not track clicks on outlinks or downloads

  When should I not install this plugin ?

  If you have developed a custom Piwik plugin that contains for example the name of your business in any of the following names we recommend to not install this plugin as it might be tracked :

  • name of a plugin
  • name of a controller action
  • name of a report
  • name of a widget
  • name of an API method

  Plugins that are installed via the Marketplace should not pose a problem as their names don't contain any user specific information such as the name of your business.

  The data is tracked as efficiently as possible as to not slow down your Piwik server. If you already have some performance challenges with your Piwik, we recommend not to install this plugin.

  Which data is tracked ?

  When the plugin is activated, the following data will be tracked :

  • The pages and reports that are viewed
  • The visitors' software and devices data like the used browser and the resolution
  • Some clicks or interactions with certain selectors or buttons. For example we track an event when a segment is selected (but we do not track the actual segment name or value).
  • In a daily task we track the following data :
    • Piwik version
    • PHP version
    • Number of websites
    • Number of users
    • Number of segments
    • How often which API method was called (only plugin name and method name but no parameters) and how long the API calls took on average.

  Are there any prerequisites ?

  • If sending usage data to Piwik is enabled, the Piwik installation must be connected to the internet
  • If tracking to a custom Piwik installation is enabled, your Piwik installation and your Piwik users must be able to connect to this instance

  Where can I report any issues with the plugin ?

  If you experience any issues with the plugin please create a new issue. The source code is available under GPL v3+ on GitHub. We always appreciate pull requests and suggestions to improve this plugin.
