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)

The IP address the statistics is sent from

Opting out

npm and Vaadin 14+ (using npm)

Using npm, you can disable it for the machine by running

npm explore @vaadin/vaadin-usage-statistics -- npm run disable

or you can disable it for the project by adding

   "vaadin": { "disableUsageStatistics": true }

to your project package.json and running npm install again (remove node_modules if needed).

You can verify this by checking that vaadin-usage-statistics.js contains an empty function.

Vaadin 10 - 14 (using Bower)

Add to your pom.xml:

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

Bower

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.
