No you don't. When you stop the subscription, you still get to keep the catalog with all that is stored in it. The Library module in Lightroom Classic will continue to function.
Direct quote from Adobe: "You can continue to access all your photos on your local hard drive through Lightroom for the desktop. You can continue to import and organize photos and output your edited photos through Export, Publish, Print, Web, or Slideshow. Access to the Develop & Map modules and Lightroom for mobile is not available after your membership ends."
