Enhanced FreeModel

Enhanced FreeModel is a browser extension for FreeModel users who manage one or more accounts. It reads the `freemodel.dev` login state from your browser, saves account snapshots that you add manually, and shows account usage, remaining balance, request count, and token statistics in the extension popup. Key features: - Keep a clearer usage / remaining-balance view on the FreeModel usage page. - Save the currently signed-in FreeModel account from this browser. - Manually import a Cookie request header copied from the browser Network panel. - Save multiple accounts and view aggregated available balance, plan remaining balance, and extra balance. - Refresh one account or all accounts, rename saved accounts, and delete accounts. - Switch between usage and remaining-balance views. Privacy notes: - The extension only accesses `freemodel.dev`. - Cookies, account labels, and the latest usage result are stored locally in `chrome.storage.local`. - The extension does not upload Cookies, account information, or usage data to a developer server. - The extension does not include analytics SDKs, ad SDKs, or remote code.
