🧠 ReMemory

ReMemory protects your files by splitting a key among people you trust. You decide how many must come together to unlock them — three of five friends, two of two partners, whatever fits. No single person can access anything alone. Based on Shamir's Secret Sharing.

Each person gets a bundle with everything they need to recover. It works in any browser, offline*, with no accounts or servers. If this website disappears, recovery still works.

How it works

Your files are encrypted. The key is split into pieces. When enough people bring their pieces together, the files are unlocked.

What this is and isn't

It is:

  • A tool that runs in your browser, offline*
  • A way to split a secret key among people you trust
  • Open source (Apache-2.0)
  • Self-contained — recovery works without this website

It isn't:

  • A service or a company
  • An account system or cloud product
  • Something that stores your data anywhere
  • A backup solution by itself

See how it works

  1. Download the demo bundles
  2. Open bundle-alice/recover.html in your browser
  3. Drag Bob's and Camila's README files onto the page
  4. When enough pieces are added, the files unlock

This is the closest thing to what a real recovery feels like.

Why I built this

Two things led me to build ReMemory.

First, I watched a documentary about Clive Wearing, a man who has lived with severe amnesia since 1985. Seeing how fragile memory can be made me think about what would happen to my digital life if something similar happened to me.

Second, I've had several concussions from cycling accidents. Each time, I've been lucky to recover fully — but the reminders add up.

ReMemory came out of that: a way to ensure the people I trust can access what matters, even if I can't help them.

ReMemory keeps growing. Check the changelog to see what's new.
