Are there ongoing costs after a year?
If you purchased your theme and paid its full price (not via a subscription plan), then after 1 year, the support for your theme will be paid.
However, if you have a recurring subscription, there are no additional fees as long as the subscription is active.
If you purchased any of our paid plugins like FloPictime, FloForms Pro, FloHub/Superdo, then again, there are no additional fees as long as the plan is active.
