Deletes the caller's account, per app: a verified key revokes every key of the identity behind it that carries the same label (each MapMap app labels its own key), and, when no other active key remains on the identity, deletes the account itself and erases its email, IP addresses and user agents. An unverified (`provisional`) key revokes only itself, and deletes the account only when it is the account's sole key: anyone who types an address can mint one, so it never speaks for the account. On the store-review identity any key deletes only itself, because that address is not a secret (security check M3). Idempotent: a retry with the same, now revoked, key answers 200 with `already_deleted`.

true when this was a retry with a key the endpoint had already revoked; nothing was changed by this call.

Always true on a 200: the calling key is revoked. A verified key takes every key of its account that carries the same label (the same app) with it; an unverified key only itself.

Whether the account's email address was erased. false while another active key remains on the account (see keys_remaining), and for the store-review identity (see review_identity).

null when the calling key was unverified. Such a key may have been requested by anyone who typed the address, so the answer must not tell it whether anyone else holds a key there: the response is the same whether the account was kept or, the key being the only one ever issued for the address, erased with it. message and retained state both possibilities.

Prepaid credit left on the account when it was deleted, in pence. It is not refunded by this endpoint. null when the calling key was unverified, for the reason given under email_erased.

Whether the calling key was verified. A verified key speaks for its account and is told what happened to it; an unverified key speaks only for itself and is not (see email_erased).

Active keys still on the account after this call: another MapMap app's key, or keys created with a different label. Deletion by a verified key is per app, so the account and its email are erased only when this is 0. null when the calling key was unverified, for the reason given under email_erased.

Keys revoked by this call (0 on a retry).

One sentence for a person.

true for the App Review identity: the account, its email and its review label are kept so the reviewer can sign up again with the same address and get the same verified key, and its IP addresses and user agents are erased. A key on it deletes only itself (its address is not a secret, so a key minted by someone else must not be able to revoke the reviewer's); keys_remaining counts the others.
