What is the difference between dangerous, normal, and signature?

Dangerous permissions need a runtime prompt and can be refused. Normal permissions are granted at install with no dialog. Signature permissions are only granted to apps signed with the platform certificate, which ordinary apps cannot obtain.

Is this the complete list of Android permissions?

No. It is a curated set of permissions that show up in real apps. System internals and OEM-specific permissions are left out because their behaviour varies by brand.

Should I be worried if an app asks for location?

It depends on the app. A navigation app asking for precise location is expected; a wallpaper app asking for it is not. Judge whether the request fits the stated purpose.

Can I deny these permissions?

Yes, for dangerous permissions. An app must keep working after a denial, so if it breaks completely, that is a sign the permission was essential rather than optional.

Android Permissions Reference

Search every Android runtime permission and what it actually grants.

Loading tool…

Android Permissions Reference on Loonix helps you search Android permissions by name and see what each one actually grants, whether it needs a runtime prompt, and why an app might ask for it.

How to use

Search by permission name, by group, or by what it seems to grant.
Read the note on what the permission actually allows.
Compare the set a real app asks for against what its stated purpose needs.

Features and limitations

Search by permission name, by what it grants, or by the language you are searching in.
Explains dangerous, normal, and signature as three different technical mechanisms rather than three levels of danger.
States the risk in plain terms, for example what a location permission can actually reveal.
Curated rather than exhaustive, and says so, because system internals behave differently per manufacturer.

Limitation: A curated set of permissions that appear in real apps rather than the full platform list, and it does not cover system internals or OEM-specific permissions whose behaviour varies by brand.

Use cases

Decide whether a permission request matches what an app claims to do.
Look up the full name and risk of a permission you only saw in a log or a settings screen.
Get the runtime-prompt rule straight when reading Android documentation.
