Hi,
Not sure I understand your question. Both are true of course. You can buy a subscription for our download and support service for one year. It's not a recurring payment, that is you just pay for one year, you won't be charged automatically each year. At the end of the year, you can purchase another year if you wish to renew. Or not. The software will continue to operate regardless of whether you have a subscription with us, on as many sites as you need.
Maybe you think you're purchasing a license to use our extensions? you're not. As with all Joomla! extensions listed on the Joomla! Extensions Directory, ours are released under the GNU/GPL license. You're purchasing access to our downloads of new versions and ability to ask direct questions to us about using our software. And of course, what you're really buying is us continuing development of sh404SEF and Josetta.
