01 / FIRST-TIME SETUP

From install to Protected, without the backup jargon.

Calmbu makes the safe choices obvious and keeps advanced storage controls out of the way.

Calmbu finds supported agents

Supported native Windows Codex and Claude Code workspaces are detected automatically, with a clear review before protection begins.

STEP 01 / DETECT

You save the recovery code

Copy, save or print the private machine-independent code, then confirm its final five characters.

STEP 02 / KEEP THE KEY

Calmbu proves recovery

The first encrypted backup must pass private recovery checks before setup can finish.

STEP 03 / EARN PROTECTED

02 / THE RECOVERY CODE

One private code. A way back on another PC.

The code unlocks the encrypted vault independently of the original computer. Keep it private and somewhere separate from the PC Calmbu protects.

Calmbu does not receive or escrow the code
Saving a new code invalidates the previous one
Never store the only copy beside the protected PC

Copy, save or print it

Choose a method that will still be available if the computer is lost.

Keep it separate and private

A password manager, secure printed copy or other private location works well.

Use it on a replacement PC

The code unlocks a copied vault without relying on the lost machine.

03 / WHERE THE BACKUP LIVES

Start with the location that fits your risk.

Calmbu recommends an available OneDrive folder because it can survive loss of the PC. You can also choose other suitable storage.

OneDrive

Recommended when available for a protected copy that can survive device loss.

External drive

Simple physical separation. Disconnect it when stronger ransomware resistance matters.

Another local location

Useful for convenience, but not enough on its own if the whole PC is lost.

Optional resilient replica

Advanced storage can add a second protected copy without changing everyday use.

04 / BEFORE YOU INSTALL

Everything you need. Nothing surprising.

Which computer do I need?

A 64-bit Windows 10 or Windows 11 PC with supported local native Windows agent state to protect.

Do I need administrator access?

No. Calmbu installs for your Windows account and runs daily Safety or change-aware Live Guard protection with least privilege.

Do I need to close Codex or Claude Code?

No for normal purpose-built backup and first-time protection. Calmbu is designed to capture supported native Windows agent state consistently.

What happens if I close Calmbu?

Closing the window does not stop scheduled Safety or Live Guard protection. Interrupted verification resumes or restarts safely.

05 / READY

Install once. Keep building.
