CallSecure: Privacy-secure

CallSecure Privacy + security of your incoming call: it will handle the call with three different modes: Normal, Family, and Emergency. It only allows calls from numbers stored in the device contacts or configured in the modes, but emergency calls will ring through. The user can also see the analytics of the application working on the incoming calls.

## 📋 Call Modes

### 2. **Family Mode**
