This project provides an Android application for blocking unwanted calls and SMS messages, targeting Android 10+ users seeking a customizable and privacy-conscious solution. It offers a flexible filtering system that can be configured via various criteria, including contact status, call history, and custom regular expressions, aiming to reduce spam without replacing the default messaging or calling app.

How It Works

The app operates by intercepting call and SMS notifications, rather than replacing the default handlers. For calls, it functions as a Caller ID app. For SMS, it filters notifications, leaving the messages in the default app. Its filtering logic is extensive, checking against contacts, contact groups, STIR/SHAKEN attestation, call repetition, dialed numbers, and custom rules. It also includes features like "Call Alert" for specific SMS triggers, "Recent Apps" to allow calls from recently used apps, "Meeting Mode" to silence calls during meetings, and an "Off Time" setting for uninterrupted periods.
