## Remaining Tasks

### High Priority

1. **API Key Authentication**

   - [ ] Backend already supports `startDate`/`endDate` params

### Medium Priority

4. **Background Jobs**
   - [ ] Periodic domain verification checks
   - [ ] Event retention cleanup (delete old events per plan)
   - [ ] Monthly IP salt rotation for privacy

5. **Input Validation**
   - [ ] URL allowlist/denylist for abuse prevention
   - [ ] Stricter input sanitization

6. **Testing**
   - [ ] Add tests for new auth endpoints
   - [ ] Add tests for billing endpoints
   - [ ] Add tests for API key endpoints

### Lower Priority

7. **Print-Ready QR Options**
   - [ ] High contrast mode toggle
   - [ ] CMYK color support

8. **Advanced Analytics**
   - [ ] Export analytics data (CSV/JSON)
   - [ ] Scheduled reports

9. **Webhooks**
