-
-A timed prompt asking the user to opt-in or out is displayed the first time cordova is run.
-It lasts for 30 seconds, after which the user is automatically opted-out if they don't provide any answer.
-In CI environments, the `CI` environment variable can be set, which will prevent the prompt from showing up.
-Telemetry collection can also be turned off on a single command by using the `--no-telemetry` flag.
-
-**Usage Example:**
-
-```bash
-cordova telemetry on
-cordova telemetry off
-cordova build --no-telemetry
-```
