+### Redemption Code System
+Promotional codes that grant users premium access. **Codes can only be redeemed on the website, NOT in the mobile app.**
+
+**Database Tables:**
+- `redemption_codes` - Stores codes with max_uses, current_uses, expiration, active status
+- `code_redemptions` - Tracks which users redeemed which codes
+
+**Components:**
+- **Admin UI** (`apps/admin/src/pages/RedemptionCodesPage.tsx`) - Super admins can generate, manage, and view redemption codes
+- **Edge Function** (`apps/supabase/functions/redeem-code/`) - Validates and processes code redemption
+- **Database Function** (`redeem_code(p_code)`) - Atomic redemption with validation (active, not expired, has uses remaining, user hasn't redeemed)
+
+**Flow:**
+1. Admin generates code in admin dashboard
+2. User enters code on website (NOT mobile app)
+3. `redeem-code` edge function calls `redeem_code()` database function
+4. On success, user's `profiles.is_premium` is set to `true`
+
+**Important:** Do NOT add redemption code UI to the mobile app. Apple requires in-app purchases for premium features purchased within iOS apps.

 ## Mobile UI - DO NOT CHANGE
