The licence is quite vague. I'd recommend actually attaching an official LICENSE file in the repo which states what users are considered personal/research, and what are commercial.
Author here. I'm not a lawyer so I can't write anything too official myself, and after some searching it seemed like none of the standard open-source licenses apply to this use-case.
Consider AGPL.. so if a prisma-like clone comes along, they cannot use it without also releasing web code.
