Terms

Updated 2026-11-05. These terms are the license you get with DuoBadge.

Who sells it

When you pay by card, Polar sells DuoBadge to you as the seller of record: it takes the payment, charges any sales tax or VAT, and sends the receipt, under its own buyer terms. When you pay in USDC, you buy from us. The right to use DuoBadge comes from us, under these terms.

Paying in USDC

• The price is 29 USDC for Single App and 79 USDC for Studio, which is 29 and 79 US dollars. Nothing is added to it at checkout.
• Your order gets a deposit address of its own, on the network you choose: Base, Arbitrum One, OP Mainnet, Polygon PoS or Ethereum, and only USDC on that network counts. The order stays open for 14 days.
• A payment up to 0.50 USDC short of the price is accepted, to cover an exchange's withdrawal fee.
• A blockchain payment can't be reversed, and anything sent in another token, on another network, or after the order has closed is not credited. Write to us with the transaction link and we will look into it.
• When the payment is confirmed, your unlock code appears on the order page and we email it to you.

What each license covers

• Single App: exports without a watermark for the App Store listings of one app, in every language and on every storefront.
• Studio: the same for any number of apps, plus the command line tool, for one person or one team's build machines.
• Neither expires. Updates through version 1 are included.
• The one-app limit is a license term, not a lock: nothing counts your exports.

What you may not do

• Share or publish your code, or resell the tool. Delivering exports to a client whose app you build is fine.
• Change or remove the code check to unlock exports for yourself or anyone else.

Your screenshots

Your captures and exports are yours. They are rendered in your browser or on your computer; we never receive them.

Apple

DuoBadge is not made by or affiliated with Apple. Whether App Store Connect accepts a screenshot, and what your product page shows, is Apple's decision. We check size and alpha before you download; we cannot promise Apple's review.

Warranty and liability

If you buy as a consumer, the law where you live may give you a guarantee that DuoBadge works as described, and nothing here reduces it. Beyond that, it is provided as is. To the extent the law allows, our total liability is limited to what you paid.

Refunds

See Refunds: 30 days, no questions asked. A refund ends the license for that purchase.
