Hi, Sami. Thanks for your interest in our plugin suite.
All our purchases are for 1 year and are setup for automatic renewal (unless you deactivate it in your account).
Each of our products have Personal, Business, Agency, Multisite, and Unlimited level licenses. Personal means 1 site for all products except Event Aggregator, which allows for “up to 100 scheduled imports per day”.
I hope this clears things up.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
