Google Maps app finally lets you manage your own profile
As AndroidPolice points out, previous versions of Google Maps would only allow users to check their Local Guides points, so the options to edit and manage public profiles are more than welcome for those who want to do it from the mobile app.
You can also choose to hide your public contributions on your profile. You can head to Menu / Your profile / More / Profile settings and turn off Show contributions on your profile. Of course, your name, photo, and bio will always be found on your profile and anyone will be able to see this information.
One other important option is to make your profile invisible for businesses if you won't want to be bothered by any of these. Keep in mind that this is a server-side update, so you'll have to wait until Google makes it available for your device.
