Here’s something nobody really tells you when you set up a new phone: giving an app microphone permission doesn’t just let it use your mic while you’re actively in the app. That permission stays granted in the background — meaning if an app is running background processes, it could potentially access your mic — unless you’ve specifically restricted it.
It sounds a little unsettling, but it’s not a conspiracy. It’s just a default that most people never think to change.
The good news is you can take that access back. On Android, Google’s own support page walks you through it: go to Settings, then Apps, find the app, tap Permissions, and you’ll see exactly what you’ve allowed. From there you can tap any permission — including microphone — and switch it to “Don’t allow.” Done. You can also set some permissions to “Only while using the app,” which is usually the smarter middle-ground option.
On Windows, it works the same basic idea. Microsoft’s support page points you to Start → Settings → Privacy & security → Microphone, where you can see which apps have access and turn it off for any of them.
If you’re on an iPhone, head to Settings → Privacy & Security → Microphone to see and manage the same list.
The thing worth understanding is that you probably said yes to a bunch of these permissions without thinking much about it. An app asks, you tap Allow so you can keep using it, and that’s that. But “Allow” is often permanent until you manually go back and change it. Granting permission doesn’t automatically go away when you close the app — you have to go back and remove it yourself.
So do a quick audit. Open your phone’s settings, find the permissions or privacy section, and look at what has microphone access. You might be surprised. Any app that doesn’t genuinely need your mic to function — cut it off. Takes less than a minute, and you’re back in control.
