Cloud Clipboard works without an account, and unlocks cloud sync when you sign in. Account controls live in the right sidebar under Account.
Anonymous vs signed in
| Mode | What you get |
|---|---|
| Anonymous | Editor works on this device only. Content stays in local storage. Images stay as local blobs (no public image URLs). No cloud sync. |
| Signed in | Same content syncs to your other devices. Images upload and become public img.* URLs. Sidebar shows cloud usage and retention. |
Anonymous content is not merged into the cloud automatically. After you sign in, if the cloud is empty and this device still has local content, a dialog asks whether to upload it.
Register
- Open the sidebar → Register.
- Enter a real email (disposable domains are blocked).
- Either set a password (at least 8 characters), or check Register without password.
- Click Register. You are signed in on this device immediately.
Email verification is tracked, but you can sync before verifying.
Sign in and passwordless accounts
- Sign in uses email + password.
- Accounts created with Register without password cannot use password sign-in until you set a password via Forgot password.
- You can add a password to a passwordless account; you cannot convert a password account back to passwordless.
Forgot password
On the Sign in tab, enter your email and click Forgot password. The email link opens a reset dialog on the homepage. After you save a new password, every device session is revoked — sign in again with the new password.
Sign out and delete
- Sign out ends only the current device session. Other devices stay signed in.
- Delete account soft-deletes the account, emails you a zip of your content, then permanently clears cloud data after 30 days.
