Sometimes, you may see in your Shopify Activity Feed that LimeSpot has updated your theme. It'll look something like this:

Rest assured that LimeSpot does not modify your theme. The only file that we ever access and modify us limespot.liquid, our helper code which sometimes needs updates for new functionality.
