They do make it clear...

  # privacy
  we store your key fingerprint, not the full public key.
  no IP logging. no tracking. no analytics.
  chat messages and game scores are stored in
  postgres, tied only to your fingerprint.
  don't trust us? use a throwaway key:

  $ ssh-keygen -t ed25519 -f ~/.ssh/late_throwaway && ssh -o IdentitiesOnly=yes -i ~/.ssh/late_throwaway late.sh
  generates a disposable key — zero risk, full experience

Wow, this got flagged immediately. Must have triggered some automated thing. Sorry!
