ILTFY I Left This For You
About ILTFY

A secure digital legacy vault

Messages, letters, photos, and documents for the people who matter most—delivered only when you're gone.

How it works

Four steps

1

Create your vault

Sign up and choose your encryption level. Your vault is yours alone.

2

Add items

Write messages, upload photos, attach documents. Anything you want someone to have.

3

Set recipients

Choose who receives each item. A letter for your daughter, photos for an old friend, documents for your partner.

4

Check in periodically

A simple “I’m still here” button. Miss it, and after a grace period, your vault is delivered.

Security

Three encryption modes

Every vault has an encryption mode chosen at creation. Once items exist, the mode is locked.

No encryption

Content stored as-is. Simplest option—suitable if your items aren't sensitive.

Server-side encryption

Content encrypted at rest with a server-held key. Protects against raw database access, but the server can technically decrypt.

End-to-end envelope encryption

A vault key is generated in your browser and never leaves it. Each recipient gets their own key, wrapped with the vault key. The server only stores ciphertext—it cannot read your items. A recovery key lets you restore access on a new device.

Delivery

Dead-man's switch + human verification

Your vault has a check-in interval (default: 30 days). Miss a check-in and a grace period begins. If the grace period expires without a check-in, delivery is triggered.

You can also designate trusted verifiers—people who can confirm your passing and trigger delivery immediately, bypassing the timer. This adds a human layer to the automated process.

Infrastructure

Built on Cloudflare

ILTFY runs on Cloudflare Workers with D1 (SQLite) for structured data and R2 for media files. There is no centralized cloud provider reselling your data. Compute and storage are distributed globally, close to where you are.

Authentication is handled by Clerk. No analytics. No ad networks. No tracking pixels.

Philosophy

Why this exists

We spend our lives accumulating things to say and assuming we'll have time to say them. ILTFY is the space between that assumption and reality.

This isn't a social network. There are no feeds, no followers, no engagement metrics. It's a quiet place to prepare for the inevitable with dignity—and to make sure the people you love aren't left wondering.
