Terms of Use

Last updated November 5, 2026

These terms cover your use of the Quack app. By creating an account you agree to them. The short version: Quack is software for checking the weather and making yes-or-no predictions on live weather markets. Your money stays in a wallet only you control, and you can lose what you put into a prediction.

1. What Quack is (and isn't)

Quack shows official weather readings and forecasts, and lets you make predictions on live markets about the weather, like the high temperature in a city on a given day.

Predictions are placed on Polymarket, a public prediction market Quack doesn't own or run. Quack shows you the market, prepares your order, and you approve it. Polymarket's rules for each market decide how it settles.

Quack isn't a bank, broker, or adviser. Nothing in the app is financial advice. Balances aren't bank deposits and aren't FDIC-insured.

2. Who can use Quack

You must be at least 18 (or the age of majority where you live) and use Quack only for yourself.

Polymarket doesn't allow new orders from some countries and regions, including the United States. Quack checks your location before every prediction and won't place an order where Polymarket doesn't allow it. Don't try to get around it.

One account per person.

3. Your risk

Every prediction can lose. You may lose everything you put into a prediction.

Prices move. What you see can change before your order fills, and an order may fill at a slightly different price or not at all.

Markets settle on the official source named in their rules, usually a specific weather station's reports. Quack doesn't decide outcomes and can't change them. Forecasts in the app are forecasts, not promises.

Cashing out early sells your prediction back to the market at whatever it's worth right then, which may be less than you put in.

4. Your wallet and money

When you sign up, a wallet is created for you that only you can sign with. Quack never holds your money and can't move it without you.

Deposits and withdrawals go through Polymarket's bridge. Send only supported tokens on supported networks; sending the wrong token can lose it.

Polymarket charges a fee on some trades. Any Quack fee is shown before you confirm.

5. Changes and contact

We may update these terms. If changes are significant we'll tell you in the app.
