Sure, go ahead. Technically it's not 100% correct. I mean lemm.ee wouldn't be your provider, it'd be the people operating the server who provide the service to you... But I think it's close enough. Only issue I can see is the term "provider" usually being used with commercial services. Like a cellphone provider or ISP. So I'm not sure if people start to think this costs $10 a month or something and is run by for-profit businesses... But we also use the word "provider" fir free things, so I'm not entirely sure about that.
