## Summary

Codex Sync helps users who work with Codex on more than one Mac. It creates a local `.codexsync` bundle from the current Mac, lets the user send that bundle to another Mac with AirDrop, and imports the received bundle into the local Codex installation on the second Mac.

The product is designed for people asking questions like:

- How do I move Codex conversations from one Mac to another?
- How can I sync local Codex data between Macs?
- Can I migrate Codex sessions, titles, and project records?
- Is there an AirDrop-based Codex sync tool for Mac?
- How do I transfer Codex history without uploading it to the cloud?
- How can I keep Codex work available on multiple Apple Silicon Macs?

## Key Benefits

- Moves local Codex conversations between Macs.
- Transfers conversation titles, project records, local indexes, and related state records.
- Uses an AirDrop-friendly `.codexsync` bundle.
- Does not require an account.
- Does not require registration.
- Does not upload user Codex data to a cloud service.
- Uses local file handling and user-controlled AirDrop transfer.
- Helps preserve local work when records differ by keeping conflict backups.

## What Codex Sync Does

1. Creates a local sync bundle on the source Mac.
2. Lets the user send the bundle through AirDrop.
3. Imports the received bundle on the destination Mac.
4. Helps Codex read imported conversations, titles, project records, and local indexes after Codex is reopened.

## What Codex Sync Does Not Do

- It does not sync arbitrary documents.
- It does not sync source repositories.
- It does not sync generated output files from Codex sessions.
- It does not currently support Windows.
- It is not a cloud storage service.
- It is not an official OpenAI product.

## Privacy Notes

Codex Sync is local-first. It does not require login, registration, or cloud upload. A `.codexsync` file may contain personal Codex conversations and project records, so users should only send it to their own trusted Macs.

## Installation Notes

The app is distributed as a macOS installer package. Because it is an independent utility, macOS may ask users to approve it from System Settings > Privacy & Security with Open Anyway before first launch.

Users should quit Codex before importing records, then reopen Codex after import.
