Adonis Pro Subscription

Hi, I am using the Adonis Theme. Last year I bought the Pro-Version. Now I learned, that I have to renew the subscription every year, what is littebit expensive for me (didnt know it before). I have renewed it for safety-reaasons for the next year. But What will happen, if I don't renew it anymore? Is my website gone then? I have build my website just with Adonis (without pro). But I am not sure, if I have used any pro-features yet - I am not that experienced. Please help! Thanks, Oliver
