What this site stores
The simulator is a set of static files that run in your browser. There is no account, no database and nowhere for your load data to go. This page names everything it writes and the two requests it makes off your machine.
It runs on your machine
- No account, no email address, no sign-in
- No cookies. The site sets none, and reads none
- Page views are counted only if you allow it, and even then without cookies, without an identifier kept in your browser, and without advertising
- Your dimensions, quantities and saved scenarios are never transmitted — the simulator’s own code contains no network calls at all
Five keys, on your device
These go to your browser's localStorage so your setup survives a reload. They stay on the device that wrote them and are readable only by this site. The first four are what makes the tool work at all — without them it forgets everything the moment you reload — so they are not something there is a choice about. Only the measurement below is optional.
clStateV1
The current setup: transport unit and its interior dimensions, pallet and box dimensions, layers, tiers, parts per box, part weight, which panels are open, the zoom level and the view angle.
clScenariosV1
Scenarios you have saved by name, each holding a full copy of the setup above plus the date you saved it.
clShowEmptyV1
Whether the empty-space overlay is switched on. A single character.
clThemeV1
Your light or dark choice, shared across every page on the site.
clsConsentV1
Your answer to the counting question, so you are not asked again. One word: granted or denied.
If storage is unavailable
Every read and write is wrapped so that a private window, blocked site data or a full disk cannot break the tool. It runs normally and simply forgets your setup between visits.
Removing it
Reset to defaults in the Cargo panel clears the current setup but deliberately keeps your saved scenarios. To remove everything, clear site data for this domain in your browser settings — there is no server-side copy to request the deletion of.
Share codes
A share code is your setup and scenarios encoded as text in your own browser. It is not uploaded anywhere. Wherever you paste it, that destination sees it — so treat a code as you would the dimensions and quantities inside it.
Two external requests
Google Fonts. The pages load two typefaces — the stylesheet from fonts.googleapis.com and the font files from fonts.gstatic.com. Your browser makes those requests directly, which means your IP address, user agent and the referring page reach Google, governed by their privacy policy rather than this one. Nothing about your load is included.
Vercel Web Analytics — only if you allow it. A small script counts page views, so we can see which pages are actually used. It records the page you opened, the page you arrived from, and coarse device and country information. It sets no cookie and keeps no identifier in your browser, and nothing about your load — dimensions, quantities or saved scenarios — is included. Vercel handles it under their own privacy terms. Nothing is requested until you say yes. Refuse, or simply never answer, and the script is never fetched — this is not a flag checked afterwards. Change your mind either way with Cookie settings in the footer of any page.
Those are the only two requests the site makes to anyone. The simulator itself makes none: its code contains no network calls at all, which is why your load data has nowhere to go. If you would rather the fonts were not fetched either, they can be self-hosted alongside the other files and the stack falls back to a real system face without them.
Hosting
The files are served by Vercel, which like any web server records ordinary request logs — IP address, timestamp, the page requested and the user agent. That is standard server operation and is separate from anything the simulator itself does.
An individual, in Québec
CargoLoadStudio is built and operated by an individual based in Québec, Canada, trading as Spratus. It is not a registered company. Québec's Law 25 applies, with Canadian federal law (PIPEDA) behind it, alongside whatever applies where you are.
Person in charge
Law 25 asks that whoever is responsible for protecting personal information be named publicly. That is the operator of this site, in person, reachable at team.spratus@gmail.com — for any question about this page, to ask what is held about you, or to have something corrected or deleted.
Turning the counting off
The one piece of technology here that observes anything is the page-view counter described above, and it does not run unless you allow it. The choice is yours to make and to remake at any time, from Cookie settings in the footer of any page. Nothing else on the site identifies, locates or tracks you.
Where it is held
The files are served by Vercel, whose servers are outside Québec, so ordinary request logs are held outside the province. Nothing you enter into the simulator is among them — it never leaves your browser in the first place.
There is unlikely to be anything to send you. No account exists, nothing you enter is transmitted, and the storage described above sits on your own device where only you can reach it. A request for a copy, a correction or a deletion can be answered honestly in one line — and you can carry out the deletion yourself, immediately, by clearing site data.
This page describes how the software behaves, verified against the source rather than written from intent. It is not legal advice and it is not a substitute for a privacy policy reviewed for the jurisdictions you operate in.
The terms the tool is offered under are on the terms of use page.
