Configuring Your License Key

You can configure your license key in two ways:

Through the App

1. Log in to the application
2. Navigate to Admin → License
3. Enter your License Key
4. Click Save

Via Environment Variable

Alternatively, you can set the LICENSE_KEY environment variable.

License Verification (Call-home)

ALTCHA Sentinel periodically verifies your license by contacting our license server at eu.altcha.org. As of version 1.15.0, no telemetry data is sent during this request. Only the following minimal details are transmitted to distinguish individual instances:

• Application version
• Node ID
• Process ID

No sensitive data or application content is ever transmitted outside your environment.

Ensure that your firewall allows outbound connections to eu.altcha.org.

Tip

You can disable the “call-home” mechanism by using LICENSE_JSON instead of LICENSE_KEY. The JSON file is provided as an attachment in the license purchase email.
