Privacy Policy

Last updated November 5, 2026

Quack collects as little as it can. Here's what it uses and why.

What we collect

Your email, to sign you in (handled by our login provider, Privy).

Your wallet addresses and your public trading activity on Polymarket, which is on a public blockchain.

The cities you pick, stored on your phone.

Privy (login and wallet), Polymarket (orders, deposits, withdrawals), and the weather data providers the app reads from. We don't sell your data.

Before an order, the app asks Polymarket whether trading is allowed where you are, using your connection's location.

You can sign out at any time, and delete your account in You → Legal & privacy. Questions: support@tryquack.com.
