+# F-Droid submission notes
+
+## Anti-features: Play Services dependency
+
+The app includes `com.google.android.gms:play-services-location:21.3.0` for better location accuracy via `FusedLocationProviderClient`. However, this is **not a hard dependency**:
+
+- The app checks for Play Services at runtime via `GoogleApiAvailability`
+- If unavailable, it falls back to `LocationManager` (standard AOSP API)
+- All core functionality (finding shelters, compass navigation, offline maps) works without Play Services
+
+This was specifically designed to support degoogled devices (LineageOS, GrapheneOS, /e/OS).
+
+### F-Droid build options
+
+**Option A: Accept as-is with `NonFreeDep` anti-feature**
+The app works fully without Play Services. Mark with `NonFreeDep` anti-feature.
+
+**Option B: Build flavor without Play Services (recommended)**
+Create a `fdroid` product flavor that excludes the Play Services dependency entirely. The fallback code paths already handle the absence — only the dependency and the Fused provider code need to be conditionally included.
+
+## Metadata structure
+
+```
+fastlane/metadata/android/
+├── en-US/          # English (default)
+├── nb-NO/          # Norwegian Bokmål
+└── nn-NO/          # Norwegian Nynorsk
+```
+
+Each locale contains `title.txt`, `short_description.txt`, `full_description.txt`, and `changelogs/` with per-versionCode files.
+
+## Screenshots
+
+Screenshots still need to be added to `images/` directories:
+- `phoneScreenshots/` — at least 3 phone screenshots
+- `featureGraphic.png` — 1024x500 feature graphic
+
+## Build instructions
+
+Standard Gradle build, no custom steps needed:
+
+```
+./gradlew assembleRelease
+```
