Terms and conditions

These terms govern your use of this website (www.arn.pw) and any web development services you order from BistuAI ("we", "us"). Separate written project agreements, where they exist, take precedence over these terms.

1. What we provide

We design, build, deploy and maintain websites and web applications, and carry out related work such as SEO, performance and accessibility improvements. We are not a hosting provider, a payment processor or a certification body, and we do not resell such services under our own name.

2. Quotes and scope

Prices published on this website are starting prices and are not offers. Work is performed only under a written scope and fixed quote that you have approved. Anything outside that scope is quoted separately before it is carried out; we will not perform unapproved billable work and then invoice you for it.

3. Payment

Unless your project agreement says otherwise, projects are invoiced in two parts: a deposit before work starts and the balance on completion. Maintenance plans are invoiced monthly in advance. Invoices are payable within 14 days. We may pause work on overdue accounts after giving you notice.

4. Your responsibilities

You agree to supply content, brand assets, approvals and access in a timely manner, and to hold the necessary rights to everything you supply. Timelines assume this cooperation; where a delay is caused by missing input from you, we will tell you and adjust the schedule rather than silently miss a date.

5. Ownership and licences

On receipt of full payment, ownership of the deliverables created specifically for your project, including source code and design files, transfers to you. Third-party open-source components remain under their own licences, and pre-existing tools, libraries and internal templates that we reuse across projects remain ours; you receive a perpetual licence to use them as part of your deliverable. We may describe the work publicly and link to it unless you ask us in writing not to.

6. Use of AI in delivery

We use AI agents and automation for a substantial part of our work, including code generation, refactoring, content drafting and automated checks. Every deliverable is reviewed by a person before it reaches you, and on request we will tell you which parts of a deliverable were AI-generated. You are responsible for final approval of content and functionality before launch.

7. Third-party services

Projects typically depend on third-party services such as hosting, registrars, analytics, payment gateways and open-source packages. Their terms, pricing and availability are outside our control, and we are not liable for their outages, price changes or discontinuation. We will name any third-party dependency and its cost before it is introduced.

8. What we do not promise

We do not guarantee search engine rankings, traffic volumes, conversion rates or revenue, because these depend on factors we do not control. We do not claim any security or compliance certification. Any figure we publish about our own work can be substantiated on request; if you find a claim on this site that cannot be, tell us and we will correct it and record the correction in the changelog.

9. Warranty and defect correction

We correct defects in our own work, that is, deviations from the agreed scope, free of charge for 30 days after launch. This does not cover new requirements, content changes, third-party breakage, or modifications made by others after handover. Beyond that period, corrections fall under a maintenance plan or are quoted separately.

10. Limitation of liability

To the extent permitted by applicable law, our total liability arising from a project is limited to the fees you paid us for that project. We are not liable for indirect or consequential loss, including lost profit, lost data or business interruption. Nothing in these terms excludes liability that cannot lawfully be excluded.

11. Confidentiality

We keep your non-public business information confidential and use it only to deliver your project. We expect the same of you regarding our methods, quotes and internal tooling. This obligation survives the end of the engagement.

12. Termination

Either party may end a project in writing. You pay for work completed and accepted up to that point, and we hand over what has been paid for. We may decline or discontinue work that is unlawful, that we are not competent to perform, or that would require us to make claims we believe to be untrue.

13. Website content

The content of this website is provided for information. We keep it accurate and correct errors when we find them or when they are reported, but we do not warrant that it is complete or current at every moment. Prices, timelines and service descriptions may change; the version in your signed quote is the one that binds us.

14. Governing law

These terms are governed by the laws of the People's Republic of China. Disputes will first be addressed through good-faith negotiation; if that fails, they may be brought before a competent court in the jurisdiction where we are established.

15. Changes to these terms

We may update these terms. The date at the top of this page shows the current version, and material changes are recorded in the changelog. Terms in force when you approved a quote continue to apply to that project.

16. Contact

Questions about these terms: email mingxinai@agentmail.to or call 13911373183 (also reachable on WeChat). Full contact details are on our contact page.
