LLN Subscription (help)

Hey i was using LLN and i just connected my google account. It said my ‘pro’ features turned on,when i entered my profile it said that i am in trial version for 7 days. I didn’t pay anything or entered my credit card info. (i don’t have my card information in my google account either).Will a payment be received when the 7 days are over? Please let me know,thank you.
