Yes. I have set up a minimal server that performs two daily checks of the modification date of an empty text file. If the last modification date is behind by a week, my loved ones get an email announcing another mail that will be sent a week later. This email includes descriptions to my KeePass containers and where to access them. In addition to a goodbye message for my close ones.

The one week buffer has saved my butt a couple of times already. And the callback is really simple. I created a Tasker task that touches the file in the morning once I unlocked my phone. So there is really not much work involved.
