Terms of Service

These terms apply when you use emberwavelabs.com, buy an EmberWave product, or order an EmberWave service. Please read them before you buy.

1. The seller

EmberWave is the trading name of ABROUGUI KHOLJENE, an individual based in Shanghai, China, who makes the products and provides the services. For product orders, Creem is the merchant of record and the seller shown on your receipt. Contact: hello@emberwavelabs.com.

2. Payment and merchant of record

• Product orders are processed by Creem, which acts as merchant of record. Creem's own checkout terms also apply to the payment, and Creem handles payment, sales tax or VAT where it applies, and receipts.
• Prices are shown in USD on the Products and Services pages.
• Services are paid in full before work starts, by invoice, after the scope is agreed in writing.

3. Digital products and licence

• Products are digital files delivered by download after payment. No physical item is shipped.
• One licence covers one buyer or one team. Your team may use and adapt the files for its own projects and studies. RoverKit may also be used for your own commercial work, as its LICENSE.txt says.
• You may not resell, sublicense, publish, redistribute or share the files outside your team. The free Rover Design Checklist may be shared as long as its footer stays on the page.
• EmberWave keeps the copyright in all products.

4. What the products are, and are not

• EmberWave tools, templates and requirement packs are first-order planning and educational aids. Their models and engineering requirements are not yet compared with hardware data. Worked examples, sample reports and filled examples are illustrative.
• They are not an engineering sign-off, not a design review of your rover, and must not be the sole basis for safety-critical decisions, regulatory approval or final design sign-off.
• Competition packs summarise official rules in EmberWave's own words. EmberWave is not affiliated with, sponsored by or endorsed by any competition organiser. Where a product differs from the official rules, guidelines or Q&A, the official documents win. No product predicts or affects a judging decision.
• Products are provided as is. A product description states its version and the date of the sources it used. Unless the product page says so, there are no updates after purchase.

5. Services

• Each service has a written scope agreed before payment: the document or question, the guideline or standard, the size, the deliverables and the delivery date.
• Reviews are comments-only documentation reviews, not engineering sign-offs. EmberWave does not write, edit or submit your documents, and makes no promise of a score, a pass, or acceptance by organisers, judges, customers or review boards.
• Public, non-controlled information only. You must not send EmberWave anything that is export-controlled, classified, or that you do not have the right to share. Companies, and teams with a company sponsor, sign a written "not controlled" statement before any file is sent.
• EmberWave does not accept work for military or defence end users or sponsors, or for parties on sanctions lists, and runs a sanctions screen on the payer before invoicing. EmberWave may decline any request.
• You are responsible for checking that your competition rules allow a paid outside review.
• Deliverables are yours to use within your organisation or team. EmberWave keeps its own methods, templates and tools.

6. Refunds

See the Refund Policy.

7. Liability

To the extent the law allows, EmberWave is not liable for indirect or consequential loss, or for decisions you make based on a product or a review. EmberWave's total liability for any order is limited to the amount you paid for that order. Nothing in these terms limits rights you have under consumer law in your country that cannot be limited by agreement.

8. This website

The site is provided for information. We try to keep it accurate, but product and service details may change; the version shown when you buy applies to your order.

9. Governing law

These terms are governed by the laws of the People's Republic of China, without affecting any mandatory consumer rights in your country. Please contact us first; most questions can be settled by email.

10. Changes and contact

We may update these terms. The version posted on this page on the day of your order applies to that order. Questions: hello@emberwavelabs.com.
