Effective 4 November 2026
When these terms apply
These terms apply when you hire Mattix for consulting, programming, or a care plan. The prices on the services page are starting rates in US dollars. They are not a quote for your project until Mattix confirms the scope in writing.
A donation, a film, or a novel chapter is not an engagement under these terms.
Scope and changes
Work starts after you accept a written scope: what will be done, what will not, the price, and the date. A change in scope is a new agreement. Mattix will say so before doing the extra work.
You provide access, decisions, and materials on time. Delay on that side moves the date.
Fees and invoices
Fees are in US dollars unless an invoice says otherwise. An invoice is payable by the date written on it, through the method named there. When that method is MetaMask or Trust Wallet, the payment is ETH, SOL, or BTC at the market rate when you confirm, and you confirm it in the wallet. Work can pause if an invoice is overdue.
Monthly care hours expire at the end of that month. They are not a bank of unused time.
Your materials and the result
You keep ownership of materials you provide. After the invoice for a programming delivery is paid, you receive the agreed result and may use it for the purpose described in the scope. Mattix keeps the right to reuse general know-how that is not unique to your project.
Mattix may mention the engagement in a portfolio unless you say not to before the work starts. Confidential details stay confidential.
Confidentiality and liability
Each side keeps the other's non-public information private and uses it only for the work. This does not cover information that is already public or that must be disclosed by law.
Liability for a paid engagement is limited to the fees you paid for that engagement. Mattix is not liable for lost profits or for how you use the result after handover. Nothing here limits liability that the law does not allow to be limited.
The practice is based in Cambodia and Hong Kong. These terms follow the law that applies to that practice. Write to contact@mattixs.com before you start if you need a different arrangement.
