Terms of Service

Last updated: October 30, 2026

These terms apply when you buy a PHP upgrade service from QiYuan Labs LLC, a Wyoming limited liability company ("we", "I"), through this website or a payment link we send you. By paying, you ("you", "the client") agree to them. For upgrades and maintenance we also sign a short written agreement that lists your system, the tested flows and the price; if that agreement and these terms differ, the signed agreement wins.

1. Services

• Upgrade Check-up ($300). A static scan of your code including bundled libraries, a dynamic property check, one runtime smoke test of the key flows we agree on, a written list of issues, and a fixed-price quote for the upgrade. Delivered within 5 days of receiving a working copy and your answers to our intake questions.
• Fixed-price upgrade. Your system, as named in the written agreement, made to run on the target PHP version (PHP 8.4 by default) with no PHP errors on the tested flows. Includes the dependency updates that requires, before-and-after test results, a list of what was and wasn't tested, and a written deployment and rollback plan.
• Maintenance ($200 per month). A monthly security update check for PHP and your dependencies, a smoke test re-run after your host changes PHP versions, and up to 2 hours of small fixes per month. Unused hours don't roll over.
• Add-ons. Environment setup when you don't have a working copy, $150 (adds 3 days). Extra revision round, $150 (adds 2 days).

Delivery times start when we receive a working copy and your answers to the intake questions, and are extended by any delay on your side.

2. Not included

Unless the written agreement says otherwise, these are separate jobs with their own quote: adapting to new platform versions or APIs (for example WooCommerce HPOS order storage), replacing abandoned third-party SDKs, writing new automated tests, new features or redesigns, security audits, hosting or server work, data migration, paid plugin or license fees, and deploying to your live server. An upgrade is not a security certification.

3. What you provide

• A working copy of your system (a staging site, or the code plus a database export that runs) and the version details we ask for.
• Access through accounts created for us, not shared personal logins. Please never send passwords by email or in a form; we'll agree on a safe way.
• Confirmation that you have the right to share the code and data with us.
• A contact who answers questions within a few business days.

4. Your live site, backups and deployment

All work happens on a copy, never on your live system. You are responsible for backups of your live system. By default you or your host deploy the upgrade using our plan, after taking a fresh backup. If you'd like us to handle the go-live, we quote it separately and only touch your live system with your written go-ahead and a confirmed backup.

5. Payment

• The Check-up is paid in full upfront. If you order the upgrade within 30 days of receiving the Check-up report, the full $300 is deducted from the upgrade price.
• Upgrades are paid 50% when the written agreement is signed and 50% on acceptance, unless the agreement sets other milestones.
• Maintenance is billed monthly in advance and can be cancelled any time; it ends at the close of the month already paid.
• Prices are in US dollars and exclude any sales tax that may apply. Payments are processed by Stripe; we never see or store your full card number.
• If you found us on a marketplace such as Fiverr or Upwork, that marketplace's payment and order terms apply, and all payments stay on that marketplace.

6. Cancellations and refunds

• Check-up: full refund if you cancel before we receive your working copy. Once work has started, the fee is non-refundable. If we can't deliver the report, for example because the copy can't be made to run and you decline environment setup, we refund the fee minus the work already done, up to a full refund.
• Upgrades: if either side ends the job early, you pay for the work done up to that point, measured against the milestones, and we refund any amount paid beyond that.
• To request a refund, email hello@qiyuanlabs.ai.

7. Acceptance and 14 days of free fixes

You have 5 business days after delivery to test and tell us about any tested flow that doesn't work on the target PHP version. We fix those and re-deliver. If you report nothing in that time, or deploy the upgrade to your live system, the work is accepted.

For 14 days after delivery, we fix at no charge any problem in the tested flows caused by the upgrade. This doesn't cover changes made by you or others after delivery, hosting or server changes, later updates to plugins, platforms or libraries, or code paths we didn't test. Beyond this, the services are provided without other warranties, to the extent the law allows.

8. Limitation of liability

To the extent the law allows, our total liability for any claim related to a job is limited to the fees you paid for that job (for maintenance, the fees paid in the 3 months before the claim). We are not liable for indirect or consequential losses, including lost profits, lost revenue or lost data, especially where no backup was kept.

9. Confidentiality and your data

We keep your code, data and business information confidential and use them only to do the job. Where possible, please send a database copy with personal data removed or replaced. Tell us before sending health information, payment card data or children's data, so we can agree on a safe approach first. We delete our copies of your code and database within 30 days after the job ends and confirm on request. We won't name you as a client without your written permission.

10. Ownership

Once you've paid in full, you own the changes we make to your code. We keep our own general tools, scripts and know-how, and you may use any of them we deliver with your system. Open-source and third-party components stay under their own licenses.

11. General

We work as an independent contractor. These terms are governed by the laws of the State of Wyoming. If a dispute comes up, we'll first try to settle it by talking in good faith. Notices can be sent by email. We may update these terms; the version in force when you paid applies to that purchase.
