How It Works

The extension reads usernames on X/Twitter to search for related prediction markets from Limitless, Polymarket, and Kalshi. This processing happens entirely in your browser — no data is sent to our servers.

Anonymous Analytics (Optional)

With your permission, we collect anonymous usage events such as:

• When the extension is loaded
• When a market badge is opened
• Which platforms are used most

This data is fully anonymous — no user IDs, no cookies, no IP addresses. You can opt out at any time in the extension settings.

Third-Party APIs

The extension connects to public APIs to fetch market data:

• Limitless Exchange (api.limitless.exchange)
• Polymarket (gamma-api.polymarket.com)
• Kalshi (api.elections.kalshi.com)

These connections only retrieve public market data. No personal information is transmitted.

Your Rights

• Opt out of analytics in extension settings at any time
• Uninstall the extension to delete all local data
• No account required — ever
