Cordova Telemetry, what is it and why use it?

Question

started a project with plain Cordova. This message keeps turning up:

You have been opted out of telemetry. To change this, run: cordova telemetry on. 

Did a short search on this, but find mostly error messages. Can some one enlighten me on what this Cordova Telemetry is and what is its use?

Answer 1

Cordova telemetry is a part of the cordova cli and collects data about your usage of it. From the Apache Cordova CLI Privacy Policy:

• IP address
• OS type and version
• Node version
• Cordova version
• Commands executed, time of execution and status (success/failure)

You can turn on/off from the cordova cli (cli reference) by:

cordova telemetry on cordova telemetry off 

Answer 2

cordova telemetry collects developer data of the usage of cordova for the cordova dev-team. The data is shown here:

It is NOT collecting user data, just developer data, like which version of cordova you are using.
