BaltazarStudios, LLC. Android applications do not collect any information that may uniquely identify your device (such as AndroidID) or any other personal information about you (such as name, address, email, phone number, or address book contents) and thus cannot know who owns or uses which Android device.
The applications may access the internet as part of (1) version update check, or (2) for performing the necessary application function (such as the search for ZX Spectrum games for PlayZX application or the search for available X-Plane server plugins for Flight Sim Remote Panel application).
None of the referred applications are intended for children under the age of 13 (making this obligatory legal stuff simpler).
