BasedIn: Privacy Policy

Last updated: October 14, 2026

BasedIn ("the extension") is a browser extension that shows the country an X account is based in, as reported by X, next to usernames on x.com.

Data we collect: none. The developer does not collect, receive, store, sell, or share any personal or usage data. There are no analytics, telemetry, ads, or developer servers.

What happens on your device

• The extension reads usernames visible on x.com pages to decide which accounts to look up.
• It sends requests only to x.com (X's own "About this account" endpoint), using the x.com session already in your browser, exactly as the x.com website does. These requests go directly from your browser to X and are subject to X's privacy policy.
• Results (username → country or "unknown", plus a timestamp) and your on/off setting are stored locally with chrome.storage.local for up to 30 days. They never leave your device. You can delete them any time with "Clear cache" in the popup, or by uninstalling the extension.

Your session: The extension does not read out, store, or transmit your X password or session tokens to anyone other than x.com.

Changes: Any changes will be posted at this URL with a new date.
