Telemetry

OpenMTG does not have access to reliable usage metrics through GitHub or the Scryfall API. To better understand how many people actively use the tool, this optional feature sends a minimal daily usage signal to the OpenMTG development team.

If enabled, a random ID is generated and stored locally in your database. Once per day, a small heartbeat request is sent. This allows the development team to estimate active user counts over time.

Data Collected

An anonymous unique ID and a UTC timestamp. This ID is only created after opting in and is permanently deleted if you opt out.

Remove All Telemetry Options

To suppress all telemetry prompts and options permanently, add the following to your .env file:

NOTEL=true

Additionally, make sure your docker-compose.yml file is up-to-date with the example file in the repository. This updated compose file needs to include the line NOTEL: ${NOTEL} line under the app environment, as it allows the Docker image to see your new setting.

Once these changes have been made, re-load the container

docker compose down

docker compose up -d
