SMS app permissions: what reading and sending texts allows

We cannot see inside any app. Tick the permissions an SMS-style app asks for to see what each allows and which pairs matter most.

Tick what the app asks for. You can see this in the pop-ups it shows and under Settings, Apps, the app, Permissions. Nothing is read from your phone.

With send text messages (sms) and contacts ticked, the checker rates the set “Wide reach”. The combination that matters most: can text your contacts from your number. Reading your address book and sending texts from your number lets an app pass a link on to everyone you know, as you. This reasons from permissions only: it cannot see an app’s code, so it says what a permission could allow, not what any app does.

We cannot see inside any app, so this page makes no claim about one called Wingo SMS. An app that deals in text messages asks for powers most apps never need: reading texts means seeing one-time codes as they arrive, and sending them means sending from your number at your cost. The checker above shows what each permission allows.

In the example the checker rates the set “Wide reach” and finds 1 combination that matters. A short permission list does not make an app honest, and a long one does not make it harmful: the list only says what could happen.

Tick your own set above and every number changes. The checker reasons from permissions only, so it cannot say what any app actually does.

Common questions

What can an app do if I let it send text messages?

It can send texts from your number without opening a messaging app, so you may not see them go. They can cost money and can carry a link to people in your contacts, which is why a games app has no obvious need for the permission.

Why does reading my texts matter for my bank codes?

One-time codes from banks and UPI apps arrive as texts. An app that can read your messages sees each code the moment it lands, often before you do. Android can hand an app a single verification code without opening the whole inbox.

Does this page read the permissions from an app or my phone?

No. It reads only the boxes you tick, so it needs no file and no access to your phone. You can see what an app asks for in the pop-ups it shows and under Settings, Apps, the app, Permissions.

Does the permission checker send my ticks anywhere?

No. It is code running in your browser. What you tick is read on your device and sent nowhere. If you press the copy-link button, the ticks go into the link after the # sign, which a website never receives.
