# Task 017 — Data Cleanup & Reset Tools

**Status:** done  
**Phase:** 10 / Admin  
**Depends on:** Task 016 (admin settings)

## Objective

Safe admin-only tools to preview and delete CRM operational data with strong confirmation.

## Delivered

- `data-cleanup.service.ts` — preview, execute, scoped delete helpers
- APIs: `GET /api/admin/data-cleanup/preview`, `POST /api/admin/data-cleanup/execute`
- UI: `/settings/data-cleanup`
- Settings hub + nav link
- Post-execute notification + console audit log
