---

## 1. Human Interface Guidelines (HIG)

### 1.1 Navigation & Tab Bar ✅

- The app uses a standard bottom tab bar with three tabs: Upload, Files, and Profile.
- Tab icons use **Ionicons** (an icon set that closely maps to Apple's SF Symbols).
- Active/inactive tab colors follow iOS conventions (`#1e40af` active, `#9ca3af` inactive).
- Header styling uses a solid color background with white text, consistent with iOS navigation bar patterns.

### 1.2 Icons & Visual Assets ✅

- **App icon:** Custom `icon.png` provided at root level; Expo handles generating all required sizes.
- **Splash screen:** Uses branded splash with `contain` resize mode and matching background color.
- **Adaptive icon (Android):** Properly configured with foreground image and background color.
- **Action buttons:** Previously used emoji characters (📷, 🖼️, 📄) which render inconsistently across iOS versions. **Fixed:** Now using Ionicons (`camera-outline`, `images-outline`, `document-outline`).
- **Status indicators:** Previously used emoji (✅, ❌, ⏳, ⚙️). **Fixed:** Now using Ionicons with semantic colors.

### 1.3 Typography & Colors ✅

- Uses system fonts (default React Native text rendering uses San Francisco on iOS).
- Color palette (`#1e40af` primary blue, semantic reds/greens/grays) provides sufficient contrast ratios.
- Text sizes follow iOS recommended minimums (body text ≥ 13pt).

### 1.4 Touch Targets ✅

- All interactive elements have `minHeight: 44` or `minHeight: 48` (meets Apple's 44×44pt minimum).
- Back links, cancel buttons, and retry buttons all meet minimum touch target requirements.

### 1.5 Safe Areas ✅

- The app uses `react-native-safe-area-context` (`SafeAreaProvider`) to respect device notches, Dynamic Island, and home indicator.

### 1.6 Dark Mode ✅

- `userInterfaceStyle: "automatic"` is set in `app.json`, enabling automatic dark mode support.

## 2. Privacy & Data Usage

### 2.1 Permission Descriptions ✅

All iOS permission strings (Info.plist keys) are present and provide clear, specific descriptions of why each permission is needed:

| Permission | Key | Description |
|-----------|-----|-------------|
| Camera | `NSCameraUsageDescription` | "DocuElevate uses the camera to scan QR codes for login and to capture documents for upload." |
| Photo Library (Read) | `NSPhotoLibraryUsageDescription` | "DocuElevate accesses your photo library to select documents for upload." |
| Photo Library (Write) | `NSPhotoLibraryAddUsageDescription` | "DocuElevate saves scanned documents to your photo library." |

**Assessment:** All descriptions clearly explain the purpose, which is a requirement for App Review approval.

### 2.2 Push Notifications ✅

- Push notification permission is requested at runtime (not at launch) when the user enters the authenticated area.
- The app works gracefully without push notifications if permission is denied.
- Device tokens are registered via a dedicated backend endpoint.

### 2.3 Background Modes ✅ (Fixed)

- **Previous state:** `UIBackgroundModes` included `["fetch", "remote-notification"]`.
- **Issue:** The app does not implement background fetch (`application:performFetchWithCompletionHandler:`). Apple may reject apps that declare background modes they don't actively use (Guideline 2.5.4).
- **Fix:** Removed `fetch` from `UIBackgroundModes`. Only `remote-notification` remains, which is required for push notification delivery.

### 2.4 Privacy Manifest ✅ (Fixed)

Starting in Spring 2024, Apple requires a privacy manifest (`PrivacyInfo.xcprivacy`) for apps using specific APIs. The following required reason APIs are used by the app's dependencies:

| API Category | Reason Code | Justification |
|-------------|-------------|---------------|
| `NSPrivacyAccessedAPICategoryUserDefaults` | `CA92.1` | Used by `@react-native-async-storage/async-storage` for user preferences |
| `NSPrivacyAccessedAPICategoryFileTimestamp` | `C617.1` | Used by `expo-file-system` to read file metadata |
| `NSPrivacyAccessedAPICategoryDiskSpace` | `E174.1` | Used by Expo runtime for storage space checks |
| `NSPrivacyAccessedAPICategorySystemBootTime` | `35F9.1` | Used by React Native's timing APIs |

The privacy manifest is configured via `expo-build-properties` plugin in `app.json`, which ensures it is included in the generated Xcode project during EAS Build.

### 2.5 Tracking & Analytics ✅

- `NSPrivacyTracking: false` — the app does **not** track users.
- `NSPrivacyCollectedDataTypes: []` — no data types are collected for tracking.
- No analytics SDKs (Firebase Analytics, Amplitude, Mixpanel, etc.) are included.
- No App Tracking Transparency (ATT) prompt is needed.

### 2.6 Encryption Declaration ✅

- `ITSAppUsesNonExemptEncryption: false` — the app uses only standard HTTPS/TLS for network communication, which is exempt from export compliance requirements.

### 2.7 Data Storage Security ✅

- API tokens are stored in the device keychain via `expo-secure-store` (uses iOS Keychain Services).
- No sensitive data is stored in `AsyncStorage` or `UserDefaults`.
- Server URL is stored in secure storage, not in plain text files.

## 3. App Store Review Guidelines Compliance

### 3.1 Functionality (Guideline 2.x) ✅

- **2.1 App Completeness:** The app provides a complete, functional experience. All advertised features (camera capture, file upload, document list, push notifications) work as described.
- **2.3 Accurate Metadata:** App name ("DocuElevate"), description, and screenshots should accurately reflect the app's functionality.
- **2.5.4 Background Modes:** Only `remote-notification` is declared, which is actively used. ✅ Fixed.

### 3.2 Content & Intellectual Property (Guideline 3.x) ✅

- No third-party trademarked content is used.
- The app does not display user-generated content publicly (documents are private to each user).
- No copyrighted content is bundled with the app.

### 3.3 Business (Guideline 3.1.x) ✅

- The app does not include in-app purchases, subscriptions, or payment processing.
- No physical goods or services are sold through the app.
- Authentication is handled via self-hosted or enterprise SSO — no Apple Sign-In requirement applies (Apple Sign-In is required only when third-party social login options like Google/Facebook are offered as the primary login method; enterprise SSO to a self-hosted server is exempt).

### 3.4 Safety & Privacy (Guideline 5.x) ✅

- **5.1.1 Data Collection and Storage:** The app collects only what is necessary for its functionality (server URL, auth token, push token).
- **5.1.1(v) Account Deletion:** ✅ Fixed. Users can now initiate account deletion from the Profile screen, which opens the server's account deletion page in the browser.
- **5.1.2 Data Use and Sharing:** No data is shared with third parties or used for advertising.

### 3.5 Privacy Policy ✅ (Fixed)

- **Requirement:** Apple requires all apps to have an accessible privacy policy.
- **Fix:** Privacy Policy and Terms of Service links are now accessible from the Profile screen, opening the server's hosted policy pages.
- **App Store Connect:** The privacy policy URL must also be provided in App Store Connect during submission.

### 3.6 Login & Authentication ✅

- Two login methods are available: SSO (browser-based OAuth) and QR code scanning.
- Both methods provide clear error messages on failure.
- The app correctly handles authentication cancellation.
- Session restoration on app launch is implemented.
- **Demo Account:** For App Review, a demo account may need to be provided in App Store Connect's review notes. Ensure the review team can access a test server.

## 4. Technical Compliance

### 4.1 API Usage ✅

- No private APIs are used (all functionality comes from Expo SDK and React Native public APIs).
- No deprecated APIs are used that would trigger rejection.

### 4.2 Network Security ✅

- The app validates server URLs require `http://` or `https://` scheme.
- All API calls use Bearer token authentication over HTTPS.
- App Transport Security (ATS) is not explicitly disabled — default iOS ATS rules apply.

### 4.3 Deep Linking ✅

- Custom URL scheme `docuelevate://` is properly registered.
- Deep link handling for QR login (`docuelevate://qr-login`) and file sharing is implemented correctly.
- `WebBrowser.openAuthSessionAsync` is used for OAuth, which properly handles the authentication session lifecycle.

### 4.4 Document Handling ✅

- `CFBundleDocumentTypes` properly declares supported file types.
- `LSSupportsOpeningDocumentsInPlace: false` ensures iOS copies shared files to the app's accessible Inbox directory, avoiding security-scoped URL issues.
- The `+not-found.tsx` handler correctly intercepts iOS "Open In…" file paths.
- `UploadScreen` uses `expo-file-system` to copy external files to cache before uploading for reliable file access.

### 4.5 Crash Resistance ✅

- All network calls are wrapped in try/catch blocks.
- Error states are displayed to users with actionable recovery options (retry buttons).
- Permission denials are handled gracefully with explanatory messages.

## 5. Onboarding & First-Run Experience

### 5.1 Welcome Screen ✅

- Clean, informative welcome screen with app branding and feature highlights.
- Clear "Get Started" call-to-action leading to the login screen.
- No misleading claims or functionality promises.

### 5.2 Login Flow ✅

- Server URL entry with input validation.
- Two clear authentication options (SSO and QR code).
- Error handling with user-friendly alert dialogs.
- Back navigation available from all auth screens.

### 5.3 First-Run Permissions ✅

- Camera permission is requested at the point of use (when tapping Camera button), not at launch.
- Photo library permission is requested at the point of use.
- Push notification permission is requested after authentication, not before.
- All permission requests include clear usage descriptions.

## 6. Remaining Recommendations

### 6.1 App Store Connect Preparation

Before submission, ensure the following are configured in App Store Connect:

- [ ] **Privacy Policy URL** — must point to the server's `/privacy` endpoint
- [ ] **App Store description** — accurate description of features
- [ ] **Screenshots** — for iPhone and iPad (since `supportsTablet: true`)
- [ ] **App category** — "Business" or "Productivity"
- [ ] **Age rating** — complete the questionnaire (likely 4+)
- [ ] **Review notes** — provide demo server URL and test credentials for the Apple review team
- [ ] **Privacy Nutrition Labels** — declare data types collected (device ID for push notifications, authentication tokens)

### 6.2 Accessibility Enhancements (Recommended)

While the app includes `accessibilityRole` and `accessibilityLabel` on interactive elements, consider:

- Adding `accessibilityHint` to buttons where the action isn't immediately obvious.
- Testing with VoiceOver to ensure all screens are fully navigable.
- Ensuring all status changes are announced to screen readers.

### 6.3 iPad Support

The app declares `supportsTablet: true`. Ensure:

- UI scales appropriately on iPad screen sizes.
- Split View and Slide Over multitasking work correctly.
- Touch targets remain accessible on larger screens.

### 6.4 Localization (Future Enhancement)

- The app currently uses English-only strings.
- For broader App Store reach, consider localizing the app name, description, and in-app strings.
