I am planning to use Literata font for my marketplace item, but i don't know the license from this font.
I have tried to find, but not yet found word "license" in this link
Anyone can give me reference about the license from Literata font?
Literata was commissioned from Type Together, a font foundry. I don't find license information in their official statements, but there isn't actually a place where you can buy / download it, so nowhere to put the license either.
It is definitely not a libre font. And I don't think you have access to a copy, unless you unpack the apk and take it from there - so not a legal access at least.
In short: Right now, no use of the font (outside of Google Play Books) is allowed.
In the mean time, Literata was released with the OFL license.
When using it, make sure to only use a copy from that Github with the license and not some old font files which could have a different license.
