If you no longer want GitClear to have access to your git provider, you may revoke its access from your user settings by clicking Settings > Repository Providers then clicking the button to "Revoke Access"

Revoking access will not delete any data or close your GitClear account.

If you are the owner of any organizations or repos, revoking your Github/Gitlab authorization will result in an interruption of service. No new commits will be imported. Existing data will not be removed.
