Override accounts are tied to a GitHub, GitLab or Bitbucket Account. You can always deceide which of your repositories should be connected to overrides.io and which not. As a subscriber you can also pick and choose which repositories 'take a seat' in your subscription. Any user who has access to a repository that is connected to a subscription will be able to access it on Overrides.io. All overrides.io subscriptions therefore include unlimited users.
