What Proxy does
Proxy provides delegated checkout infrastructure for situations where the person who wants to buy something is not necessarily the person who can approve or pay for it.
Proxy helps merchants create payment handoff links, preserve checkout context, route a request to a designated payer, receive payment status signals, and return signed events to the merchant’s systems.
Proxy is not the seller of the merchant’s products or services. Proxy is not the merchant of record. Proxy is not a payment processor, money transmitter, bank, card issuer, or financial institution. Proxy does not provide the card entry UI, hold funds, or store payment card data. Payments are processed by the merchant’s payment service provider, such as Stripe or another provider selected by the merchant.

Relationship to other agreements
If you are a merchant using Proxy, your use may also be governed by a separate Merchant Services Agreement, order form, statement of work, data processing addendum, or similar agreement with Proxy. If there is a conflict between these Terms and a signed or accepted merchant agreement, the merchant agreement controls for your business use of Proxy.
If you are a payer or buyer using a merchant’s Proxy-powered handoff link, your purchase is with the merchant, not with Proxy. The merchant’s own terms, privacy policy, refund policy, subscription terms, and support policies apply to the purchase.
