@vaadin/vaadin-usage-statistics

Gathers usage statistics for components used during application development

To be able to understand and focus development more efficiently, Vaadin gathers product usage statistics from developers. No statistics or other data is collected from the users of the applications based on any Vaadin technologies.

Periodical random sampling is used to ensure only statistical data is collected. We do not track individual users.

Statistics are only gathered when the application is in development mode. Statistics are automatically disabled and the statistics gathering code is automatically excluded from production builds.

Collected data

• Vaadin products used in the application, including version numbers
• Frameworks used in the application, including version numbers
• Flow features used in the application, including version numers
• The first and last time a product was used
• The first time statistics were gathered
• Whether you are a registered vaadin.com user or not (true/false)
• Whether you are a Vaadin Pro user or not (true/false)
• Browser user-agent string
• The IP address the statistics is sent from

Opting out

To opt-out from statistics, install the no-op version of the vaadin-usage-statistics package using

bower install --save vaadin/vaadin-usage-statistics#optout

You can verify this by checking that vaadin-usage-statistics.html is empty.

If you are using Java, add to your pom.xml:

<dependency>
  <groupId>org.webjars.bowergithub.vaadin</groupId>
  <artifactId>vaadin-usage-statistics</artifactId>
  <version>1.0.0-optout</version>
</dependency>

If you have any questions on the use of the statistics, please contact [e-mail].
