Hi @agr7373
Actually after the purchase of our single themes you will get free update and support for one year from our support forum.
After one year if you want to continue with the update and support for the theme you will have to pay small amount $15 for another year.But you can continue to use the theme for the lifetime without renewing the yearly subscription.
Also our subscription renewal is not an automatically process. It’s a manual process and it’s up to you to renew you subscription or may cancel the subscription anytime. We have clearly written it on our Plans & Pricing page as well.
Thank you!
