What Happens After Cancelling GitHub Pro?
Upon successful cancellation, your GitHub Pro subscription will remain active until the end of your current billing period. At the start of the next billing cycle, your account will automatically revert to the GitHub Free plan. You will no longer be charged. Data associated with repositories will generally remain, though private repositories in organizations will change status as per the terms of the Free plan. Personal private repositories (not tied to an organization) are retained on the Free plan. Features exclusive to Pro, such as GitHub Codespaces usage beyond the Free tier, will cease to be available.
