Bring the release documents back in line with what the app now does

The checklist still recorded the first artefacts (aab 4 682 814, apk 2 081 955); re-measured at 4 836 490 and 2 155 563 and noted why they moved, that the permission set did not change, and that a stale hash is worse than no hash because it looks checked.

PRIVACY.md said the app keeps no copies of your files and deletes what you select directly. Both stopped being true when deletes started staging into the trash: the item is moved, not erased, and stays on the volume for 24 hours. A privacy policy that misdescribes deletion is not a small thing on a paid listing, so the deleting and retention sections now describe the trash, the index it keeps, and the one caveat that clearing app storage forgets the trash without emptying it.

Also flags that the screenshots show none of search, undo, trash or receiving a share.

 ## Deleting files
 
-Files are deleted only when you ask. Deleting through the app asks for confirmation first.

+Files are deleted only when you ask, and deleting asks for confirmation first. Where Android

+Android performs that deletion.
+
+For everything else the app **moves** the item into a hidden `.plainfiles-trash` folder on the
+same volume instead of erasing it, and keeps it there for 24 hours so a mistake can be undone.
+Those items are still on your device and still count against your free space until they expire;
+the app removes them by itself after that. The **Trash** screen, in the app's menu, lists what
+is still there and puts it back where it came from. The app never touches anything you did not
+select.
 
 ## Data retention and deletion
 
-The app stores a small amount of data in its own private storage: your view preferences
-(list or grid, sort order), any folder permission you granted through the system picker,
-and nothing else. This data never leaves your device. Uninstalling the app, or clearing its
-storage in Android Settings, removes all of it.

+- your view preferences (list or grid, sort order);
+- any folder permission you granted through the system picker;
+- a small index of what is currently in the trash — file names, the folder each item came
+  from, its size and when it was deleted — so that a deletion can be put back even after the
+  app has been restarted.
+
+None of it leaves your device. Uninstalling the app, or clearing its storage in Android
+Settings, removes all of it. One thing worth knowing: clearing the app's storage forgets *what
+is in the trash*, but the trashed files themselves stay on your volume until they expire, or
+until you move them back by hand.
+
+The app does not keep a second copy of your files. The trash holds the originals by moving
+them, so nothing is duplicated and no extra space is used beyond the items themselves.
