Time-Locked Messages That Only Send If I Stop Responding

Tore my achilles recently, had surgery (4th major), which reminded me of the love letters I wrote years ago before my first to be delivered in case I didn't wake up. Wondered, do others think about such morbid things and the responsibility in my case to also convey various contacts and information about our affairs my spouse isn't fully on top of?

TL;DR: I told this idea to my college freshman son who built A Final Message to deliver private letters and instructions only if user goes silent. It’s privacy-first (client-side encryption), fail-safe (cooldowns + guardian approvals), and exportable (no vendor lock-in).

Why Password spreadsheets and “email after I die” scripts are brittle and risky. I wanted something my family could trust without trusting me (or a single server) to be online forever.

Vibe coded with tech stack: Git > Vercel integrating Twilio, Sendgrid, Stripe and features like split-key release by user's option, cron driven automated check-in alerts.

Would love feedback on current pricing, vulnerabilities to worry about and target markets for kid to focus on.

Once in a week or so I will click on a link of a unique(to me) online business model.

This is that one. Imagine using this to break up with someone :D

My method is to have cron jobs on systems both in my name and not in my name that others can not control. I stop logging in, emails go out, some things decrypt, some files transfer, some controls are activated and so on. Emails have disclaimers that I may have forgotten to update a system and what process to validate I am ok. I would imagine many here could do the same.
