The body description may mention trademarks, but only:

Screenshot compliance
Per security policy + Play visual content policy:
| Item | Allowed? | Note |
|---|---|---|
| Show app’s own UI (Settings, Onboarding, Home) | ✅ | Native UI, no notification content |
| Show mock Google Maps navigation (e.g. demo route Hồ Gươm → Lăng Bác) | ✅ | Public landmarks; no real user nav |
| Show real Maps navigation with personal address | ❌ | Privacy violation — real address visible |
| Show GT5 Pro watch face with maneuver icon (mock) | ✅ | Watch face is generic Huawei UI |
| Show NaviCast logo | ✅ | Self |
| Show “Google Maps” logo or icon | ❌ | Trademark — except in screenshot of its own notification on phone (incidental fair use) |
| Show “Huawei Health” logo | ❌ | Trademark — except in onboarding screen 3 instructions where we say “open Huawei Health” with text, not logo |
| Show watch model name in screenshot caption | ⚠️ | OK as factual description (“Tested on Watch GT5 Pro”); avoid implying endorsement |
If screenshot includes a real Maps notification with addresses, blur before submission.
