About

Altbook helps you organize multiple Flyff Universe browser accounts safely and conveniently.

Account switching: Open separate Flyff Universe sessions in different tabs, each isolated with its own cookies and login, so you can switch between accounts without logging everyone out.

Credential vault (optional): Store credentials locally according to your settings so signing in across accounts is quicker and stays on your machine under your control.

Macros: Define simple, user-triggered hotkey actions for the game page. Macros only run when you choose to use them; there is no unattended botting.

Altbook account & licensing: Optional sign-in with api.altbook.app unlocks paid tiers and device limits; the extension checks your license and version over that API.

This extension is built for players who manage several characters or accounts in the browser version of Flyff Universe. It does not modify game files and does not load or execute code from the internet beyond normal extension updates from the Chrome Web Store.
