Use them, including commercially and in a modified form, provided you credit the
author. A free licence rather than a reservation, deliberately: F-Droid's
inclusion policy weighs an app's assets as well as its source, and artwork held
back earns the NonFreeAssets flag. CC BY rather than the GPL because the GPL
would oblige the editable SVGs to ship as the artwork's source, and they are not
in this repository — what is committed is generated from them.


THE NAME

"Rubber Ring" is not licensed by either grant above. Give a fork its own name:
the code is yours to take, and so is the artwork if you credit it, but two apps
answering to one name serves nobody looking for either.

Nothing here is a registered trademark, and this is not claiming to be one. It
is a statement of what the licences do and do not cover.
