+### `/delete-account/` (2026-10-30)
+
+Play needs one account-deletion address from whoever publishes the app. The platform gained
+self-service deletion on the website and in the app (`docs/website/ACCOUNT_DELETION.md`, AD1), and
+this page is the address Play is given (AD2, §4.5 there). It cannot delete anything: we hold no
+account, so it explains where the button is in the app and on the website, what goes and what stays
+and for how long, and who to ask when you cannot sign in.
+
+**The facts are one row.** What a deletion takes is the `deploy-account-deletion` row in
+`src/data/collection.mjs`, whose `deletion` field holds the website's own words for what goes and
+what stays (`client/src/lib/accountDeletion.js`, which the app's strings repeat) plus how long each
+kept thing is kept, which Play asks and the screens do not say. `/privacy` section 3 renders the row
+as prose, the page renders its lists, and `PLAY_DATA_SAFETY.md` prints them under the console's
+deletion questions, so the three cannot disagree. `deletionRow()` throws when the row is missing,
+and `test/legal.test.mjs` fails a kept entry with no retention. The app rows that deletion touches
+(the session, the trust token, push and the inbox snapshot) say so, and `lastUpdated` moved.
+
+**D85 — The page is linked from the footer, `/privacy` and `/app/`** (org lead, 2026-10-30). The
+footer's legal bar reads Privacy · Terms · Delete account, because a player looking for it looks
+where the privacy link is; `/privacy` sections 2 and 3 and the bottom of `/app/`'s "Two ways to get
+it" link to it as well.
+
+**D86 — Someone who cannot sign in is sent to their community's operator, never to us** (org lead,
+2026-10-30). The page offers "Forgot your password?" first, which works when the account has an
+email address and the site can send mail, and then the operator, who can delete any account from the
+admin panel. It says plainly that we cannot do it: we hold no account and have no access to any
+community's site. Offering our contact address to help find an operator was considered and declined.
+
 **What phase 6 also closed.** `/privacy/` and `/terms/` were the last two entries in
 `checkLinks.mjs`'s `PLANNED_ROUTES`; building them emptied the list, and its reverse check is what
 forced the deletion. The list itself stays, because §10's documentation routes land in phases 7 and 8

 Push is off until you enable it. When you do, the app mints a random, unguessable topic name on the notification relay the deployment nominates, and registers that topic’s URL with the deployment so it has somewhere to send a nudge. What actually travels through the relay is content-free — a stream name and a reference, never the message — and the app then fetches the real content over its authenticated connection to the deployment. A leaked topic name therefore reveals nothing, which is the reason the relay needs no account and holds nothing about you.
 
 - **Why that answer:** The topic URL is an address for this device, and the app sends it to the deployment. The relay is the one the deployment nominates to deliver its own notifications, so it carries them on the deployment’s behalf rather than receiving a share. It only ever sees a topic name and a tickle; the app pulls the content itself, authenticated. No hop reaches a server we operate.
