-  | # | Tag | Why it is unambiguously true of this app |
+  The live list (checked 2026-10-14) contains **no cleanup-specific vocabulary at all** — no
+  *Storage*, *Photo cleanup*, *Duplicate photos*, *Photo management* or *Photo gallery*. Across
+  the whole photo domain Play offers only *Photography*, *Photo editor* and *Photo frame*, so
+  exactly one tag is both available and honest:
+
+  | Tag | Verdict | Reason |
   |---|---|---|
-  | 1 | **Duplicate photos** | The literal function, and the phrase a user types into search. |
+  | **Photography** | ✅ use | The app's subject *is* the user's photo library, and someone who reads "find duplicate photos" sees immediately why the tag is there. This is the only photo-domain tag that applies. Available while the category is *Tools*; if the category is *Photography* it is the category itself and therefore redundant. |
-  | 2 | **Photo cleanup** | How the short and full description frame the job ("find and remove"). |
+  | **Privacy & security** | ⚠️ optional | Defensible: the listing *leads* with "no internet permission at all", "no account, no tracking, no analytics", and that is visible to an unfamiliar user — Google's test. But it pulls in people browsing privacy tools who are not after a photo cleaner. Add it only if that discovery surface is wanted. |
-  | 3 | **Photo management** | Google's own one-line description of the *Photography* category is "Cameras, photo editing tools, **photo management**, and sharing" — so this tag matches their taxonomy wording. |
+  | *anything else* | ❌ | Nothing else in the list describes this app; see below. |
-  | 4 | **Storage** | The benefit the listing leads with: `03-results.png` shows 17 groups and 83.5 MB reclaimable. |
-  | 5 | **Photo gallery** | The thing being managed; swap it if *Suggested tags* offers something closer. |
 
-  If a *Suggested tag* is a better match than #4 or #5, take the suggestion — the full taxonomy
