End-to-end encrypted · zero-knowledge

Your Claude, on every machine.

Continuum keeps your ~/.claude — every chat, your memory, your settings — in sync across all your machines. Encrypted end-to-end, so no one but you can ever read it.

Open a session on your laptop, pick it up on your desktop. Nothing left behind.

Zero-knowledge

We can't read your data. That's not a promise — it's math.

Your files are encrypted on your machine with a key that never leaves your devices. The relay that moves them between your machines only ever sees ciphertext. A breach, a subpoena, a rogue admin — all of it yields nothing readable.

What you get

Continuity, without the trade-off.

Every reason to sync your work, none of the reasons not to.

🔐

End-to-end encrypted

XSalsa20-Poly1305 on your device. The server stores sealed blobs it can't open.

🖥️

Every machine

Mac, Windows, Linux. Start on one, continue on another — the context is just there.

🧠

Chats, memory, settings

Your whole ~/.claude — transcripts, memory files, config — kept in step.

🔑

Your key, your data

The encryption key is generated on your machine and never sent to us. Lose it, and even we can't help — by design.

🔀

Conflict-free merge

Append-only transcripts merge deterministically; edits reconcile without clobbering.

Runs in your tray

Install, pair once, forget it. It watches and syncs quietly in the background.

Three steps

Set up in under a minute.

Install

Run the installer on your main machine and open Continuum. No account, no config to wrestle.

Pair

Continuum gives you a pairing code. Paste it into Continuum on your other machines to link them.

Done

It syncs continuously in the background, end-to-end encrypted. Open Claude anywhere and pick up where you left off.

Built for teams that ask hard questions

Security you can verify.

Continuum is architected so that trusting us is optional. The design minimizes what the service can even access — and we document exactly what that is.

Read the security overview
  • Zero-knowledge relay — stores ciphertext + opaque metadata, never plaintext or file paths.
  • Keys never leave your device — derived and held client-side only.
  • TLS in transit, authenticated encryption at rest — tampered data is rejected.
  • Hashed tokens, per-tenant isolation, quotas & rate limits — abuse-resistant by design.
  • Published threat model — we tell you what a breach would and wouldn't expose.

Stop losing your place.

One install, one pairing code, and your Claude follows you everywhere — privately.
