Thank you for reaching out to us. If you buy the 29.99 USD version, you’ll get one year of updates and support. It’s an annual subscription. It must be renewed on an annual basis. If you buy a one-year license and don’t renew it, the plugin will still work, but you won’t receive any updates after the first year.
I hope you found this information beneficial. If you have any questions or need assistance, please contact me.
