What we collect

WhaleHalla collects minimal data to provide our services:

Google Sign-In: If you sign in, we receive your email address and display name from Google. We do not store your Google password or access your Google account data beyond basic profile information.
Paper Trading data: Your simulated positions, trade history, and balance are stored in our database (Cloudflare D1) to enable cloud sync across devices.
Analytics: We use Google Analytics 4 (GA4) and Google Tag Manager to understand how features are used. This includes anonymized page views, feature usage events, and general device/browser information. No personally identifiable information is sent to GA4.
Local storage: We store preferences, display name, and session data in your browser's localStorage. This data never leaves your device unless you explicitly sync.

We do not collect wallet addresses, private keys, or any blockchain credentials.
We do not track your real trading activity on Polymarket or any other platform.
We do not sell, rent, or share your personal data with third parties.

We use first-party cookies only for Google Analytics and Google Sign-In functionality. No third-party advertising cookies are used.

Your account data is retained as long as your account exists. You can request deletion by contacting us at polyedge-support@googlegroups.com.

Cloudflare: Hosting and CDN. Subject to Cloudflare's Privacy Policy.
Google: Sign-In and Analytics. Subject to Google's Privacy Policy.
Polymarket: Market data is fetched from Polymarket's public APIs. We are not affiliated with Polymarket.
