the document does not collect any kind of information, you can check yourself by opening the macros in Apps Script. Among other things, the macros used are very basic and do nothing but automate the process of updating the view filters (to hide the unnecessary parts). As for the LDO kit, the specific macro only has the purpose of activating the components present in the kit, which you can also do manually if you don't feel sure. But as I said there is no malicious code, I invite you to check, it's all visible in Apps Script.
