Highly certain if obtained directly from the Play Store.When a developer includes hooks in the app to gather information from outside that normally available to any app or access extra resources on your device, permission requirements are made automatically.When an app has no special permissions required, it means that it's not included any code that can get to your data or device in a harmful way.Nefarious methods have been hatched where loopholes have been found in the scheme but Google is diligent about looking for those, expelling the apps, and upgrading the development tools to prevent further occurrences - along with a software robot called a watchdog that is constantly scanning apps for violations, and removing them from the Play Store. If you've installed one that it's found to be bad, it can and will reach out to your device and remove it - and you can't stop it and there's no waste of time with dialogs. If the watchdog finds something wrong, it takes it out.No system built by people can be perfect so never say never.But within what's known and available, apps requiring no special permissions are the safest possible.
