FinalCapsule VS JavaScript.com

FinalCapsule's answer

Next.js and TypeScript, PostgreSQL, S3-compatible object storage, AES-256-GCM envelope encryption for all message content and attachments. Self-hosted on Switzerland infrastructure.

FinalCapsule's answer

The combination of true end-to-end encryption with human verification. Most dead man's switches are a simple timer: miss an email and your secrets are sent. Final Capsule adds a multi-phase process where trusted people you chose must confirm before anything is released, which protects against false triggers (a lost phone, a long hospital stay) while your content stays encrypted the whole time. We store only ciphertext and cannot read or recover anything ourselves.

FinalCapsule's answer

Three reasons. Privacy: encryption happens before your data leaves the browser, so there is nothing readable to leak, sell or subpoena. Safety against mistakes: delivery requires multiple missed check-ins plus confirmation from your designated SafeGuards, not just one ignored email. And pricing: a one-time €49 lifetime payment instead of a subscription that your estate would eventually stop paying, with a published sunset policy in case the service ever shuts down.

FinalCapsule's answer

People who hold things others would need if they were gone: parents who want to leave letters for their children, self-custody crypto holders whose seed phrases would otherwise die with them, and anyone managing the family's passwords and accounts. More broadly, privacy-conscious people doing digital estate planning without wanting to hand secrets to a lawyer or write them in a public will.

FinalCapsule's answer

It started from a simple realization: if something happened to me, my family would be locked out of everything, and the letter that would have mattered most was never written. Existing tools either required sharing secrets while alive or relied on unencrypted documents that become public at probate. So I built the third option: a sealed, end-to-end encrypted capsule, opened only for the right person, only after robust verification.
