01Project support
Payments are optional one-time support for the project selected at checkout. They are not charitable donations, are not represented as tax-deductible, and do not purchase goods or services. No product, reward, ownership interest, or future benefit is promised in exchange.
02Payment processing
Direct project support is completed on Stripe-hosted Checkout. Yuena Core also offers a Ko-fi support option connected to the project payment setup. This website does not receive or store full card numbers, bank credentials, or other payment-method secrets. Stripe and Ko-fi operate under their own terms and privacy practices.
03Refund requests
If a payment was made by mistake or there is a payment problem, use the customer-support information shown on your Stripe receipt. Refund requests are reviewed case by case. Nothing here limits rights that apply under law or payment-network rules.
04Site privacy
This is a static public project site with no user accounts and no first-party payment form. The site does not intentionally collect sensitive personal information. Hosting and payment providers may process ordinary technical or transaction data required to operate their services.
Public project funding counters are reconciled from the relevant support sources and may not update immediately after a payment. The private engineering repository, payment credentials, banking information, identity-verification records, and secret keys are not published on this site.
