There you will find the expiration date. You also have the option to renew your YTD Pro subscription.
The Pro license is valid for 1 month, 6 months, 1 year or 2 years (depending on the type of license) from the moment of purchase, for all YTD versions that are released during that time frame.
We recommend you to carefully review the Pro license terms before purchase since future versions may contain new or different license terms.
