 - **Music** (MP3, M4A, AAC, FLAC, OGG, OPUS, WAV): an album can have many tracks; they play in the hub's player and can be downloaded.
 - **Apps**: any files to download (an APK, an installer...), with an optional link and version. The hub does not run them.
 - **Sites**: any website as a card. It opens in a new tab, or inside the hub if you tick *Open inside the hub* (some sites refuse to be shown that way).
-- **Extensions**: one self-contained `.html` file that adds a feature to the hub. A person installs it from My Store and it opens inside the Store. It runs in a sandbox with no access to the hub's sign-in or data (and `connect-src https:` only), and talks to the hub through a small `hub` object: `hub.storage.get/set/all/remove` (its own settings for that person, up to 256 KB), `hub.user()` (the person's name), `hub.toast(text)` and `hub.open(url)`. It can also ask for hub data, which the person approves the first time (and which is forgotten when the extension is removed): `hub.tasks.lists() / list(listId) / add({ title, notes, due, list }) / complete(listId, taskId)`, `hub.contacts.list() / add({ name, email, phone, org })` and `hub.calendar.events(from, to) / add({ title, start, end, allDay })` (dates as `YYYY-MM-DD`, times as `YYYY-MM-DDTHH:MM`). A refused request rejects with an error. Ready-made examples are in `docs/extensions/`: **notes.html** (notes and checklists, can send items to Tasks), **tracker.html** (habit and Bible-reading streaks), **kitchen.html** (unit converter and recipe scaler that can add to your Shopping list), **weather.html** (forecast plus a verse of the day) and **notepad.html** (the smallest one).

A refused request rejects with an error. Each permission can be switched off again from the extension's **Permissions** button, and when an admin changes an extension (its version or file) the people who have it see "Updated" the next time they open it. Ready-made examples are in `docs/extensions/`: **notes.html** (notes and checklists, can send items to Tasks), **tracker.html** (habit and Bible-reading streaks), **kitchen.html** (unit converter and recipe scaler that can add to your Shopping list), **weather.html** (forecast plus a verse of the day) and **notepad.html** (the smallest one).
 
 Files are kept in the data folder under `mystore/` (up to 1 GB each; extensions up to 2 MB). Only an admin can add, change or delete items.
