Where it runs

Both put the same screening in front of the model. The difference is which machine does the screening.

Opens the Microsoft Store

Before you install

What the first launch asks of you

Each of these happens once. None of them changes how Cedreon works afterwards.

Account

A Cedreon account

The app opens Cedreon in your browser to sign in or create your account, with a password or with Google, and then signs itself in. Invited by your organization? Use the activation code from the invitation email when you create the account.

Both apps are signed. The Mac app carries a Developer ID signature and is notarized by Apple, so it opens on a double-click like any other. The Windows app installs through the Microsoft Store, and the installer it runs carries a code-signing certificate issued through Microsoft’s own signing service.

Either way

What you get on both

The same screening

One engine screens every message, whichever way you reach it. There is no lighter version of the rules.

The same vault

Values are replaced with placeholders before the message leaves, and restored for you when the answer comes back.

The same record

Every exchange is written to a hash-chained record you can read afterwards, showing what the model was and was not shown.
