Mute is designed to help you create quieter phone habits without collecting unnecessary data.
When you choose apps to mute, that information stays on your phone. Mute does not see which apps you select, what you do inside those apps, or how you use your phone.
Mute uses the permissions required to block the apps you choose — nothing more.
Your phone habits are yours. Mute is just here to help you create a boundary when you want one.
