+## App privacy policies (rendered from the app repos)
+
+`/calendula/privacy` and `/agendula/privacy` hold **no copy** of their prose.
+Each policy lives in its own app repository, as `docs/PRIVACY.md` with
+`title` / `description` / `updated` frontmatter, and is the single copy of that
+policy anywhere:
+
+| Page | Source |
+|------|--------|
+| `/calendula/privacy` | [`jlmakiola/calendula`](https://codeberg.org/jlmakiola/calendula) → `docs/PRIVACY.md` |
+| `/agendula/privacy`  | [`jlmakiola/agendula`](https://codeberg.org/jlmakiola/agendula) → `docs/PRIVACY.md` |
+
+`scripts/sync-external.mjs` clones them (shallow, single-branch, no
+credentials) into `external/` before every build and dev server — it is wired
+to `prebuild` and `predev`, **not** to CI, because Coolify builds the site from
+the repo and a checkout that only ran in a Gitea job would never reach the
+deployed page. `src/content.config.ts` exposes each file as a content
+collection; the pages render it and supply the `<h1>` from `title`.
+
+**To change a policy, edit it in the app repo, in a PR.** It reaches the live
+page on the site's next build.
+
+```sh
+npm run sync:external                       # refresh the checkouts by hand
+CALENDULA_REF=some/branch npm run build     # build against a branch
+AGENDULA_LOCAL=../agendula npm run dev      # render a working copy, no network
+```
+
+The build **fails** if either policy is missing, empty, or malformed. That is
+deliberate: a privacy page silently rendering nothing is the one failure this
+arrangement exists to prevent, and it is worth a red deploy.
+
+### Getting a policy edit onto the site
+
+A build is what publishes it, so:
+
+- **Floor:** the daily `scheduled-deploy` cron rebuilds every morning, so any
+  edit is live within a day without anyone doing anything.
+- **Immediate:** add a webhook in the app repo (Codeberg → Settings → Webhooks)
+  pointing at the same Coolify deploy URL the cron uses, so a merge to the app's
+  `main` triggers a site rebuild at once. One-time setup per app repo; the
+  secret lives in Coolify, not here.
