Getting localstorage key?

Is it possible to access the localStorage key used by a Storyline project when it's published to the web?

On the last slide, I want to clear the localStorage for that lesson so that the next student using the same device isn't prompted to resume the course.

Additionally, is it possible to use that key within the slides? For example, if I create my own localStorage key and it matches a variable, the lesson would continue from where it left off. Otherwise, it would start from the beginning.
