01 / THE GAP GIT DOES NOT CLOSE

Your code may be safe.
Your working context may not be.

A remote Git repository can restore your code. It does not automatically recreate the local Codex workspace that helped you understand, navigate and work on that code.

GIT PROTECTS

Your repository history

Commits, branches and tracked project files belong in Git. Keep using it.

Essential for your code

CALMBU PROTECTS

The workspace around it

Codex sessions, user-level settings, skills, instructions and history can live outside the repository Git protects.

Built to recover, not just copy

RISK 01

One PC becomes the only copy

If important Codex state exists only in your Windows profile, loss or failure of that device can take the working context with it.

RISK 02

Deleted or damaged state

A mistaken deletion, damaged profile or incompatible change can remove useful history before you realise you need an earlier point.

RISK 03

A new PC starts half-finished

Cloning the repositories gets your code back. It may not bring back the supported Codex sessions, settings and workspace continuity around it.

02 / HOW CALMBU WORKS

Four quiet steps.
One honest green tick.

A completed copy is not enough. Calmbu also checks that the encrypted recovery point is ready to recover.

Map the supported workspace

Agent-aware coverage protects approved local workspace data around your repositories.

Encrypt a private copy

The backup is locked on your PC before it reaches the destination you choose.

Prove it can recover

The recovery point must pass Calmbu's private recovery checks before it is called Protected.

Keep coverage current

Calmbu can update and retest supported coverage when an agent changes.

03 / CHOOSE YOUR PROTECTION

Daily calm or
change-aware protection.

Both plans encrypt, test, recover and migrate your supported Codex workspace. Choose how quickly new work becomes protected.

SAFETY

One proven backup every day.

Pick a time. Calmbu creates and recovery-tests one automatic backup daily, with Back up now whenever you want an extra point.

BEST FOR DAILY AGENT WORK

LIVE GUARD

Change-aware protection after work settles.

Live Guard notices supported changes after a two-minute quiet period and respects the configured minimum interval between runs, which is two hours by default.

Change-aware automatic protection
Less unprotected work between daily backups
Advanced recovery safeguards

04 / PRIVATE BY DESIGN

Protect the work.
Do not inspect it.

Calmbu runs on your Windows PC. Your readable Codex work is not sent to Calmbu for backup storage.

Encryption happens before destination writes Known credentials and private keys are excluded Calmbu does not receive your recovery code Safe-folder recovery leaves live state untouched

05 / SOURCES + TESTED SCOPE

06 / STRAIGHT ANSWERS

Before you choose Calmbu.

No backup jargon. Just the things a Codex user should know.

Doesn’t Git already back up Codex?

Git protects committed repository history and tracked files. Codex also keeps supported user-level sessions, history and configuration outside a repository, so the two protections solve different problems.

What Codex work does Calmbu protect?

Calmbu targets supported native Windows Codex state such as sessions, history, settings, skills, instructions and related user-created workspace state. Known credentials and disposable runtime files are excluded by default.

Does Calmbu upload my Codex work?

No. Calmbu reads and encrypts supported state locally, then writes the locked vault to the destination you choose. Your readable backup contents are not sent to Calmbu for cloud storage.

Can I use the backup to move Codex to a new PC?

Yes. A verified recovery point can help reconstruct supported Codex state on another compatible Windows PC. Repositories and sign-in credentials should still be handled through their normal secure paths.

CALMBU FOR CODEX

Do not wait for a failure
to discover what was only local.

Set up Calmbu once. Keep building with a tested way back.
