Delete Account

Delete the current user's account.

Companies are archived, the conglomerate is hard-deleted, and the user row is soft-deleted (deleted_at set). The soft-delete preserves the normalized email so the signup collision check at /auth/callback continues to block re-signup with the same mailbox, closing the referral-credit farming loop.

Two 409 refusals, distinct codes (spec 2026-09-15 §4.5): has_subscribers with the count, when a business of this account still has paying subscribers (D38), and has_active_plans when this person still pays for a plan of their own (D39). Nothing is touched in either case.
