That “Allow this app to access your location?” popup deserves two seconds of thought, not a reflex tap. This free checker explains, permission by permission, whether a request is normal for that kind of app or a reason to stop.
Permissions are not good or bad on their own. Context is everything. A maps app that wants your location is doing its job. A flashlight app that wants your contacts and your microphone is not, and that mismatch is exactly where trouble hides.
Tell the checker your phone, the type of app, and what it is asking for. You will get a plain rating for each permission, why it might be legitimate, the warning signs, and how to change it later. Nothing you enter is saved; it runs in your browser.
The question that settles most permission prompts
Before you tap Allow, ask one thing: does the feature I am about to use actually need this? A ride app needs your location to find you. A photo editor needs your photos. If you cannot connect the permission to something you are doing right now, that is your cue to deny it, or at least to wait until the app explains why.
The two permissions to be really careful with
Most permissions are limited to one job. Two are not, and they are the ones scammers ask for most:
Accessibility
Built for screen readers, but it can read everything on your screen and tap for you. Only grant it to tools you completely trust.
Device admin
Meant for work and anti-theft apps. It can lock or wipe your phone and is deliberately hard to remove. Rarely needed by an everyday app.
How the checker decides
Each permission has a sensitivity level, and each type of app has permissions that make sense for it. When a sensitive permission does not fit the app, the checker flags it higher, and it always treats the two powerful permissions above with extra caution. The result is a plain read on whether a request is normal, questionable, or a genuine red flag.
General guidance, not a scan. The checker reasons from the app category and the permissions you enter. It cannot inspect the actual app or detect malware, so a permission that is fine for one app can still be misused by another.
Who this is for
- Anyone who feels unsure when an app asks for access.
- Parents setting up a phone for a child and checking what apps request.
- People installing a new or unfamiliar app from the store.
- Anyone who taps Allow out of habit and wants to break it.
Frequently asked questions
Is this checker free?
Yes, and there is no sign-up. It runs in your browser, so nothing you enter is uploaded, stored, or logged.
Does it scan my phone or the app?
No. It gives general guidance based on the app type and the permissions you enter. It cannot inspect the app or detect malware, so treat it as a sanity check, not a security scan.
Which permissions should worry me most?
Accessibility and Device admin, because they are powerful and hard to reverse. Be cautious too with SMS, Phone, and Contacts on apps that have no clear need for them.
Can I allow a permission now and remove it later?
Yes. On both Android and iPhone you can turn any permission off later in Settings, and most apps keep working with reduced access.
What is the difference between ‘While using’ and ‘Always’?
‘While using the app’ grants access only when the app is open, which is safer. ‘Always’, especially for location, lets the app access it in the background too. Prefer ‘While using’ unless you truly need the background feature.
