## ✅ Priority 3: Profile Privacy Enforcement (VERIFIED)
## ✅ Priority 3: Profile Privacy Enforcement (COMPLETED)
### Status: IMPLEMENTED & WORKING
### Status: IMPLEMENTED & SIMPLIFIED
**Verified**:
- ✅ `get_filtered_profile()` function exists in database
- ✅ RLS policies correctly filter profile data based on privacy settings
- ✅ Privacy levels: public, private
- ✅ Banned/deactivated users hidden from non-moderators
- ✅ Field-level privacy via `can_view_profile_field()` function
**Changes Made**:
- ✅ Updated `useProfile()` hook to use `get_filtered_profile()` RPC instead of direct table query
- ✅ Removed `useProfileFieldAccess` hook (no longer needed - privacy handled at database layer)
- ✅ Simplified `LocationDisplay` component (removed redundant privacy checks)
- ✅ Simplified `PersonalLocationDisplay` component (removed redundant privacy checks)
- ✅ Removed `canViewField()` checks from Profile page (trust filtered data from RPC)
**No Changes Needed**: The privacy system is already properly implemented.
**Architecture**:
- Privacy enforcement now happens exclusively at the database layer via `get_filtered_profile()`
- Frontend components trust that if a field is present in the response, it's viewable
- Single source of truth for privacy logic (no duplication between frontend and backend)
**Security Benefits**:
- Field-level privacy enforced by security definer function
- No possibility of frontend bypassing privacy checks
- Better performance (1 RPC call instead of 8+ field checks)
- Simpler, more maintainable code
**Files Modified**:
- `src/hooks/useProfile.tsx`
- `src/pages/Profile.tsx`
- `src/components/profile/LocationDisplay.tsx`
- `src/components/profile/PersonalLocationDisplay.tsx`

**Priority**: HIGH - Should be enabled immediately.
### 2. Extensions in Public Schema (LOW RISK)
**Issue**: Supabase linter warns that extensions are in the `public` schema.
**Action**: No action required - this is a default Supabase configuration. Moving extensions could break functionality.
**Why Safe**: Supabase manages these extensions, and they don't pose a security risk in this context.

## 🎉 Implementation Complete
All automated security improvements have been implemented. The codebase now follows best practices:
- ✅ Database-layer privacy enforcement
- ✅ No client-side privacy bypass possible
- ✅ Simplified, maintainable code
- ✅ Single source of truth for security logic
- ✅ Better performance (fewer database calls)
