How long can I use Loom for free?

Could you please elaborate on the duration of the free usage period offered by Loom? I'm curious to know if there's a specific time limit after which I'll need to upgrade to a paid plan or if there are certain usage thresholds that trigger the transition. It would be helpful to understand if there are any restrictions or limitations I should be aware of before utilizing Loom's services. Thank you for your assistance in clarifying this matter.
