By popular request, we no longer store data for predictions made using the API.
User data is automatically removed from predictions an hour after they finish. The prediction itself is not deleted, but the input and output data for the prediction is removed. This only applies to predictions created with the API, but not predictions created on the website.
This is enabled for new accounts starting today, but we know that some users may be relying on prediction data to exist for more than an hour, so we've not enabled this for any existing accounts.
