# Sync across devices

Sync starts after you sign in. Open [cpcpcbcb.com](https://cpcpcbcb.com) on another device with the same account to see the same editor content.

## What syncs

- Editor HTML (text and structure)
- Images you pasted or inserted while signed in (uploaded to public image URLs)
- Changes pushed to other open sessions over a live connection when available

Anonymous sessions never call the sync APIs.

## After you sign in

If the cloud account is empty but this browser still has local content (from anonymous use or a previous session), a dialog asks whether to upload that content. Nothing is uploaded without that confirmation.

## Conflicts and offline

- If another device changed the same content while you were editing, the app asks how to resolve the conflict instead of silently overwriting.
- Offline, you can keep editing locally; when the network returns, pending changes upload in batch.
- Multiple browser tabs on the same device stay visually in sync with each other.

## Quotas and retention

Signed-in accounts are limited to:

| Resource | Limit |
|---|---|
| All clipboard HTML combined | **20MB** |
| Images | **20** |
| Cloud retention | **7**, **30** (default), or **365** days |

Retention is based on last cloud edit time. Change the period in the sidebar **Usage** section. Shortening retention may be blocked if it would expire existing content immediately.

The sidebar also shows current storage and image counts so you can see usage before you hit a limit.
