That clause is more intended for a situation where, for example, a phone manufacturer wants to include our app as a default option. That is the kind of commercial use we would prefer to negotiate and sign a special agreement for.
> You may use or modify the software only for non-commercial purposes
When one speaks of 'using' software, only one thing really comes to mind. Seems like an easy fix.
Wrote this comment with FUTO and it's pretty nice; it's certainly the first one I'm considering using over Gboard (because frankly the feature set of many FOSS keyboards is quite bad). While not FOSS, FUTO is a nice step up in terms of philosophy and actual license from most proprietary keyboards, with the exception of the commercial use restriction which really made me think twice about it.

Say I take the keyboard software/app _itself_, rebadge it as ohmykeyboard, then sell it for profit. I would be violating the license in that case.
Just typing with it and using it on a regular basis doesn't violate that part of the license.
