DeadSwitch – Encrypted USB vault with dead man's switch

Anyone wanting to leave final messages to loved ones
You write a message, record a video or audio message, or both -- attach whatever you want, add your recipients, and go live your life. Every 30 days, we check in. If you stop responding, after 90 days we assume you've died and deliver your messages.
The idea came from a real place. In my early 20s, my best friend Sean and I came up during the first dot-com boom. We were broke, dumb, and inseparable. He died of an overdose a few years later. I never told him what his friendship meant to me—not because I didn't feel it, but because that's not what guys like us did. I wrote a memoir about it (How You Wish You Could Leave), and somewhere in the process of reliving all that regret, I realized I wanted to build the thing I wished had existed.
On the technical side: it's serverless on AWS -- Lambda functions behind API Gateway, RDS, Angular frontend on S3/CloudFront, Cognito for auth, SES for email delivery, and EventBridge-triggered workers that run the lifecheck monitor and wink delivery daily. Stripe for payments.
Business model: one-time payment, not a subscription. Three tiers from $500 to $3,000 depending on how many winks and attachments you need. I didn't want to build something where people worry about their credit card expiring before they do.
Happy to answer questions about the architecture, the delivery reliability problem (how do you make sure messages actually arrive years from now), or anything else.
