The initial purchase price gets you a lifetime license for the theme, and 12 months of updates and support. After that time, if you wish to continue the subscription it is $29 for an additional 12 months of updates and support. If you do not renew the subscription you can still use the theme on your site but you will not receive further updates or have access to the support forums. More info about prices can be found on our
pricing page.
You don't need to do anything separately with regards to the database, as once you have installed WordPress and then the theme, it's already done.
You can select one language or the other, but the theme does not have a language selector by default. Thanks.
