I’ve looked at a few on fdroid and they all seem like they aren’t being maintained anymore.
Edit: I’ve spent the past day trying most all of the suggested keyboards here and I think I’ve landed on either Unexpected Keyboard or AnySoftKeyboard. Thanks for all the suggestions. Thumbkey is quite the thing to get used to.
You don’t even need GrapheneOS for that, I’m using LineageOS and can turn off internet access for apps
Yes but the Graphene community have to mention it as much as possible.
