I just use github for my secrets file, that's what I really don't want to lose. I keep the encryption key in a separate repository of course so no one can just look in and see my passwords.
It also works for important documents. Birth certificate? GitLab repository. (Not GitHub, I lie to Microsoft about my age and don't want them to know.) SSN? GitHub organisation name. Love notes from my high school crush? Duh, obviously I don't want to lose those. They're on the Blockchain, for proof of originality. Bank details? I have a website on Netlify with those. Makes it easy for all those nice foreign gentlemen on the phone to send me money.
