pdt_case autoloaded options?

I was checking in on my WP database, specifically autoloaded options. I keep seeing these pdt_case_ followed by a string of letters and numbers, and was trying to remember what it was and then after looking into some of them, I remembered I used Plugin DetecTive in the past. So my question is; if I’m no longer using the plugin, is it safe to delete these autoloaded options? Thanks!
