CW Mic Block is a privacy-focused Android utility designed to help you better understand and control microphone access on your device. The app gives you clear tools for monitoring microphone activity, reviewing which apps have microphone permission, receiving privacy alerts, and quickly managing microphone access when you want extra privacy. CW Mic Block is designed to work locally on your device. It does not record your conversations, upload microphone audio, require an account, or use advertising or analytics. Key features include: Microphone activity monitoring and privacy alerts Mic Guard for ongoing microphone awareness Microphone permission auditing for installed apps Trusted-app controls Auto Mic Lock options Temporary microphone access controls Microphone activity history Foreground privacy notifications Quick access to Android microphone privacy settings Local-only privacy settings and history No ads No account required No analytics tracking No microphone audio recording No Internet connection required for core functionality CW Mic Block can also provide additional context about recent app activity when optional Android Usage Access is enabled. This feature is optional and can be turned off at any time in Android Settings. Microphone activity information displayed by CW Mic Block is based on information made available by Android. Android may not always identify which application is responsible for a microphone session, and foreground-app information should not be treated as proof that a particular app used the microphone. Device manufacturers and Android versions may also handle microphone controls differently. For the strongest system-level restriction available on supported Android devices, CW Mic Block can help you access Android's built-in Microphone Access privacy control. CW Mic Block is built for users who want a simple, local-first way to stay more aware of microphone permissions and activity without sending their privacy information to an outside server. Your microphone. Your device. Your control.
