Lutify.me uses a hybrid model. The purchase of your 3D LUTs package is not a subscription but a single purchase. You may use the product for as long as you wish.
LUTs Previewer, included with your purchase, is a Software as a Service (SaaS) product which requires active yearly Lutify.me subscription to function. Additionally, the included support and updates for the package are a yearly subscription service.
After the first year, your license will renew automatically for the discounted price of $19.90 a year. You may cancel your license at any time.
You can cancel and renew your licenses from My Account section.
