Hi, yes, it's a Juniper and if you keep it inside, in a heated room, it will surely die.
Put it in a unheated but well-lit room (such as a conservatory) until temps are below freezing and then move it outside as soon as you can.
I think I see some pebbles on top of the substrate: remove them soon as they don't help to estimate when it needs to be watered.
Do NOT repot or trim it at all for this year, you first need to learn to keep it alive.
Good luck and let us know!
