Terms of Service

01Who this agreement is between

These Terms of Service (the "Terms") are an agreement between you and 罗智予（个人） ("we", "us") covering Maxpack (the "Service"). The web version runs at imkikoman.com/app.

You accept these Terms when you tick "I have read and agree to the Terms of Service and Privacy Policy" and sign in. The Service requires sign-in; it cannot be used while signed out. If you don't accept them, please don't use the Service.

The most important part of this document is section 05 — a load plan is a calculation, and the actual load has to be verified by you. If you read only one section, read that one.

02What we provide

The Service is a 3D container load simulator: you enter cargo dimensions, weights and quantities, and it produces a loading plan together with bearing-load propagation, centre-of-gravity offset and axle-weight figures, which you can export as a loading report.

• The Service is a software tool. It is not a transport service, not a customs service, and not professional advice of any kind.
• It currently runs in the browser only. Nothing to install.
• Optimal packing is unavailable while signed out. On an account's first valid registration, the server idempotently grants 10 points, once; signing in again, clearing browser data, changing browsers or changing devices neither resets nor re-issues them.
• JSON / XLSX template import and export are local and free. Optimal packing, animation and result export send the scene data necessary for that feature to the server for computation or generation.
• We may add, change or remove features at any time.

03Points, memberships and accounts

• An account receives 10 points once, on its first valid registration — a one-time grant, not a daily one. The server initializes it; signing in again, clearing browser data, changing browsers or changing devices neither resets nor re-issues it. Optimal packing is unavailable while signed out.
• Allowance and payment come in exactly two forms: points and membership. Three membership plans are currently on public sale: monthly, yearly and lifetime. Payment is checked manually through the WeChat Pay or Alipay channel shown in the purchase interface, or an entitlement can be activated with a redemption code. The price and order details shown when you submit the order govern that order.
• A valid monthly, yearly or lifetime plan has full feature access, allows unlimited optimal packing while it remains valid, and spends no points.
• Points are settled and deducted only after an optimal-packing result has been completely and successfully delivered. Partial, infeasible, timed-out and failed runs deduct no points, and points reserved for an interrupted run are returned by the server.
• We previously sold packs of 50, 200 and 1,000 runs. They are no longer publicly listed and no longer accept new orders; completed historical orders, and any unused balance already held on an account, remain valid.
• Result export requires sign-in and a valid paid entitlement. An account holding only granted points, which has never held a paid entitlement, may run optimal packing against its point balance but cannot export results. Once an account has held a paid entitlement, the free grant ends permanently and does not return when the entitlement expires.
• Result export also requires no cargo intersection, every item to be fully contained in exactly one actual container, and no unsupported (floating) cargo. Overweight, instability, bearing-load, axle-load and similar warnings are recorded in the result but do not block export.
• You can sign in with a one-time code sent to your phone number or email address. Once signed in, you may also set a password and use it to sign in. Keep control of your phone, mailbox and password.
• A phone number or email address can belong to only one account. You may bind both a phone number and an email address to the same account.
• We may change the size of the grant and the rules for spending points. Points already spent are not refunded.

One thing about points: the server accounts for them only by account and does not collect a device fingerprint to create, transfer or reset them. The same account reads the same balance across browsers and devices.

Anything done through your account is treated as done by you. If you think someone else is using your account, contact us as soon as you can.

You can delete your account from inside the app at any time. Deletion is irreversible; exactly what happens is described in the Privacy Policy.

04What you must not do

While using the Service, please do not:

• call the Service in bulk with scripts, crawlers or any automation, or work around our rate limits;
• circumvent, reset or forge granted points or paid entitlements by any means — including mass account registration, account theft, or rotating proxy IPs;
• reverse engineer, decompile or crack the client or the API, or repackage our computation as a product of your own;
• resell or rent out points or memberships on the Service, or embed the Service in a service you charge third parties for without our written consent;
• upload unlawful content, or use the Service to carry out unlawful activity;
• interfere with the operation of the Service in any way, including load testing, injection attacks and denial-of-service attacks.

If we have reasonable grounds to believe you are doing any of the above, we may restrict or terminate your access without prior notice.

05A load plan is a reference — you must verify the actual load

Please read this section in full. It decides who carries the loss if a plan is wrong.

The load plans, bearing figures, centre-of-gravity positions and axle weights the Service produces are reference results, computed from the data you entered, using a simplified model. They are not loading instructions and they are not a safety certification.

• Wrong input, wrong output — always. A dropped digit, gross weight entered as net, pallets and packaging left out: the plan will be wrong, and the software has no way of knowing you made the mistake.
• The model is simplified. It does not account for lashing and securing, dunnage bags and packing material, variation and wear between individual containers, dynamic loads and shocks in transit, hard braking or sea state, temperature and humidity, the way carton stacking strength decays over time and with moisture, or what the loading crew actually does on the day.
• It does not replace regulation or carrier requirements. These include, without limitation, the IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units (CTU Code), carrier and airline loading rules, road axle-load and gross-weight limits, dangerous goods rules, and the rules of the origin and destination jurisdictions. The official texts and your carrier's actual requirements always govern.

So: every plan must be verified on site, before loading, by someone with the relevant qualifications and experience, against the actual cargo, the actual container and the applicable rules. The loading decision is yours, not the software's.

To the fullest extent permitted by law, we are not liable for cargo damage, loading incidents, transport delays, fines, re-shipment, demurrage, lost profit, or any indirect, incidental or punitive damages arising from your use of, or inability to use, the Service.

Where applicable law does not allow the above exclusion to take full effect, our total liability for the matter is capped at the amount you actually paid for the Service in the 12 months before the event giving rise to the liability.

Nothing in this section excludes liability that cannot be excluded by law — for example personal injury caused by our wilful misconduct or gross negligence.

06The data you enter stays yours

The cargo dimensions, weights and quantities you enter belong to you. To complete the optimal packing, animation or result export you choose, we send the necessary scene data to the server for computation or generation.

Local JSON / XLSX template import and export do not themselves call the server and remain free. If you later use template content for optimal packing, animation or result export, the data-transfer rule in the previous paragraph still applies.

The current server code does not write the raw scene details in those three request bodies to the database. Optimal-packing results enter an in-process memory cache for up to 6 hours and may disappear earlier through capacity eviction or a service restart. Animation requests and generated animation plans, and the scene data and file contents used for result export, are not written to the database or that result cache. The server separately keeps usage records, and keeps result-export audit metadata that does not contain scene details for 90 days. See the Privacy Policy for details.

Exported loading reports are yours to use freely, including commercially.

07Our intellectual property

The software, algorithms, interface design, documentation and marks of the Service belong to us. These Terms grant you permission to use the Service as agreed; they transfer no intellectual property.

Please don't remove or obscure our marks in the interface or in exported files.

08Changes, interruption and termination

• The Service is provided according to the points or paid entitlement you currently hold, and is provided "as is" — we don't guarantee continuous availability, freedom from errors, or fitness for your particular situation. We'll do our best; we're not making promises.
• Service may be interrupted for maintenance, upgrades, migration or force majeure. We'll announce it in advance where we can.
• We may change or withdraw parts of the Service. If we shut it down entirely, we will post notice on this site at least 30 days beforehand.
• You may stop using the Service at any time, and delete your account from inside the app at any time.

The price, term and other order details are shown before you submit an order. The corresponding entitlement becomes active only after manual payment verification or successful redemption-code verification.

09Changes to these Terms

We may update these Terms. When we do, the version number and effective date at the top of this page change with them.

For material changes — new charges, a change in the scope of liability, a change in how personal information is handled — we will ask for your consent again the next time you sign in. If you don't agree, you can stop using the Service and delete your account.

Our system records which version you agreed to, so an old consent is never treated as consent to new terms.

10Governing law and disputes

These Terms are governed by the laws of the People's Republic of China (for the purposes of this clause, excluding the laws of the Hong Kong SAR, the Macao SAR and Taiwan).

If something goes wrong, contact us first — most things are settled by one email. If we can't settle it, either party may bring the dispute before the competent People's Court at our place of domicile.

The Chinese version of these Terms governs. This English version is provided for convenience; where the two differ in meaning, the Chinese version prevails.

If any provision of these Terms is held invalid or unenforceable, the rest remain in force.
