As someone who's had access to production data in the past, if it's any consolation: you see all that PII, all those order forms, and you just...don't...care.
I would write a letter in a text file, password encrypt it in a zip file, upload zip to Google drive, put a reminder in Google calendar for the date i want to open, with link & password.
At least that's why I've never used this service and never will, even though I think it would be worthwhile.
