Lunatico's smartphone apps (GNS, GNSFree, and the new Dragonfly and the pocket CloudWatcher, and any future ones) do not require nor use any sensitive data or permission. None at all.
Bluetooth apps request location information - this is an android requirement since bluetooth 4.0. We don't want that location information, won't use it, but cannot avoid the system asking for it. And it has to be granted to have bluetooth connectivity.
Not only that, but:
- the apps will only use your Smartphone storage to save its own settings
- they won't access your calls, contacts, identity... nothing at all
- the only data they'll know about you is what you configure in the settings
- ... and even that won't be shared with anyone. Ever.
