Android Location permission

Currently im working on a geolocation service for Android and iOS.

We need the location of the user for internal purposes and my question is if there is any way to get location (latitude,longitude) of the user without asking permission to allow. For example, when the user logged in, automatically send the data of his currently location without asking permission from the user.

Without asking for the permission, the app doesn’t have access to the data - that simple.
