Solutions I've seen before allow you to set a backup person that gets contacted. So, like, maybe there's a weekly email you have to reply to. If you don't respond in a day, it texts you instead. After a set period of time it will reach out to your trusted contact who can confirm whether you're okay or not.
Or worse; I dunno get hit by a bus and be in the hospital, or perhaps arrested? Friends and family don’t know what happened to you and then your death announcement blares.
I think only people expecting their death to be likely in the next year should want to employ this however, and that probably changes things.
