Morphology
The computing sense is a straightforward container metaphor: 'cookie' (a unit of data) combined with 'jar' (a container) yields a place that holds cookies/data. This compositional mapping is predictable and follows common physical-to-digital metaphor patterns, so a B1 learner who knows both constituent words can infer the meaning.
Etymology
Cookie jar comes from the simple kitchen jar where you keep cookies. People imagine children with their hands in the jar, and some adults also hide 'spare money' or small valuables there, so the name brings to mind a container for treats or hidden things.
