Export first if you may want a copy: export your data.
Erase one player
Open the player (Players, List, then the profile) and use Erase player. It needs permission to manage settings. This removes their profile, sessions and events across the organisation, including as the other side of other players' payments, trades and punishments (those rows then show an erased player), stored punishment reasons about them, and abuse flags. It completes within minutes. If an agent had buffered data for them offline, that data is erased for 7 days after the request. Purchase records are kept for accounting but unlinked from the player.
Remove a server
In the server's Settings, choose Remove server. ServerStats stops accepting data from its agent at once. Stored data expires on your plan's schedule. Delete the agent files from the game server too.
Delete an organisation
Settings, Data & privacy, Delete organisation (owners). ServerStats destroys the organisation's encryption key first, which makes every encrypted field unrecoverable, then deletes its servers and data. A live subscription is cancelled at Stripe first; if Stripe cannot be reached the delete is refused and nothing is lost. Encrypted backups that still hold the key expire within 5 weeks.
Delete your account
Account, Security. This removes your login and your membership of every organisation. If you are the only owner of an organisation, delete it or add another owner first. An account created with Discord or Google needs a password set before it can be deleted.
