FIVE requires no account, no email, and no payment. We do not collect or store any personal information.
To keep the free service available to everyone, we keep a short-lived, in-memory record of request timestamps per IP address for rate limiting. This data is never written to disk, never shared, and disappears automatically.
We do not log the content of your character descriptions or the constraint JSONs you generate.
We have nothing to sell, trade, or transfer — no personal data is retained.
