Donot Call Shield : caller id

Donot Call Shield stops spam, scam, and robocalls using Android’s official CallScreeningService API and on‑device intelligence — no account required.

Highlights
- CallScreeningService based blocking (Google‑approved)
- On‑device AI risk scoring (privacy‑preserving)
- Contacts‑aware allowlist
- Pattern detection: auto‑dialers, neighbor spoofing, repeated callers
- Night Mode and Zero‑Trust options
- Privacy‑first: no recording, no contact uploads, no data selling

How It Works
1) Incoming call triggers the CallScreeningService
2) Multi‑layer decision engine analyzes risk
3) High‑risk calls are silently blocked with a notification
4) Allowed calls ring as normal
