Hello. I'm building a school athletics results app (Vite static site, no server functions), on a Hobby account. It's still in development: from January to March 2027 I'll run free pilots at a few schools, with no payments, ads or revenue, and no paid plan planned for at least a year. Is it acceptable to host these free pilots on the Hobby plan, as a second project with a custom subdomain? I'll move to Pro before charging anyone. Thank you.
