Terms of service

1. The agreement

These terms govern your use of MachLoad, a web application operated from Hong Kong. By creating an account or paying for a plan you accept them. If you are accepting on behalf of a company, you confirm that you have authority to bind that company.

2. Accounts and seats

• You must provide a valid work email and keep your credentials secure. You are responsible for activity under your account.
• A seat is a named individual. Team plans include five seats; additional seats are $9 each per month.
• Sharing one login between several people is not permitted on Solo, and may result in suspension.
• You must be at least 16 years old and using the service for business purposes.

3. Plans, billing and renewal

Paid plans are billed in US dollars, monthly or annually. Monthly plans renew automatically every month on the date of purchase. Annual plans are charged at ten times the monthly price for twelve months of service and renew automatically every twelve months.

We send a renewal reminder by email seven days before any annual renewal. Price changes take effect at your next renewal and are announced at least 30 days in advance.

Per-plan purchases (single load plan, white-label pack, export compliance report) are one-off charges and do not renew.

4. Cancellation and refunds

• Cancel at any time from Settings, Billing, Cancel plan. No email to support is required.
• Cancellation stops the next renewal. Access continues until the end of the period already paid for.
• Monthly fees are not refunded for partial months or unused runs.
• Annual plans may be refunded in full within 14 days of purchase if fewer than ten full calculations have been run.
• Per-plan purchases are refunded if the export failed on our side; not if the plan simply produced an inconvenient result.
• After cancellation the account moves to the Free tier. Data above the Free limits is retained read-only for 90 days, then deleted.

5. What a loading plan is, and is not

MachLoad produces an algorithmic reference plan from the dimensions, weights and constraints you enter. It is a planning aid. It is not an engineering certificate, a structural assessment, a lashing design approval, or a substitute for the judgement of the person responsible for loading the container on site.

Container dimensions vary by a few millimetres between owners, packaging deforms, and handling equipment has tolerances. A plan that reports clearance close to zero should be treated as a warning, not a guarantee. You are responsible for confirming the plan against the actual container, the actual cargo and the applicable regulations before shipment.

We are not liable for demurrage, rework, cargo damage, customs delays or consequential loss arising from reliance on a generated plan. Nothing in these terms limits liability that cannot be limited by law.

6. Acceptable use

• Do not attempt to reverse engineer the solver, scrape the service, or resell access without a written agreement.
• Do not upload data you have no right to process, including another company's confidential drawings.
• Do not use the API to build a competing load planning product.
• We may suspend an account that attacks the service, circumvents quota limits with multiple accounts, or uses it for unlawful shipments.

7. Your data and your content

You keep ownership of the cargo data, drawings and packing lists you upload. You grant us a licence to store and process that content solely to provide the service. We do not use your cargo data to train models or to build a public benchmark without your written permission.

Aggregated, de-identified statistics, such as average utilisation by container type, may be used to improve the product.

8. Intellectual property

The software, the constraint library structure, the interface and the documentation remain our property. Your subscription grants a non-exclusive, non-transferable right to use the service for your own business during the subscription term.

9. Availability and support

We target 99.9% monthly availability, excluding scheduled maintenance announced at least 48 hours in advance. Support response targets are one business day for email, and four business hours for priority email on the Team and Enterprise plans.

Because the solver runs in the browser, a temporary server outage does not prevent calculation; it does prevent saving and exporting.

10. Termination

You may close your account at any time. We may terminate an account for material breach of these terms, with 14 days' notice where the breach can be remedied. On termination, the data retention rules in the privacy policy apply.

11. Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region. Disputes are subject to the exclusive jurisdiction of the Hong Kong courts, without prejudice to any mandatory consumer protection rules in your country of residence.
