Terms
KamraiDee is an app for shops that make or find what they sell. These terms cover the website, public tools, the blog, signup, and a signed-in workspace. Switch the site language for Thai.
Public beta
KamraiDee is in public beta. The Free plan is free, with no end date. Features may appear, change or be removed while we test. We will give at least 30 days' notice, in the product and by email, before any paid plan starts to charge you. You can ask us to delete your account and data at any time: email hello@kamraidee.com or message us on LINE @504rpmhu.
Effective 18 September 2026. Last updated 19 October 2026. Thai law governs this notice.
1. The service
KamraiDee (กำไรดี) helps an owner see true cost and leftover profit: stock, formulas, sellables, orders, calendar, labels, and an optional public shop at /m/your-handle. Industry packs change labels and samples only. They do not change the costing math. Same plan prices for every pack.
Sign-up is open to everyone at /signup. The public site, blog, and calculators on /tools do not need an account.
KamraiDee is run by Siam Vintage Trading Co., Ltd. (บริษัท สยาม วินเทจ เทรดดิ้ง จำกัด), company registration number 0205568013151. In these terms, "we", "us" and "our" mean Siam Vintage Trading Co., Ltd.
2. Agreeing
Using the site, creating a workspace, or staying signed in means you accept these terms and the privacy notice. If you do not accept them, do not use the service.
You must be 20 or older, or have the legal capacity to contract under Thai law. KamraiDee is a business tool, not a product for children.
3. Account and workspace
One workspace, one owner. You keep your login safe. You are responsible for what happens under your account.
You may close the workspace and ask us to delete it. How we handle personal data is in the privacy notice. Shop records you typed stay yours. Export what you need before you leave if you want a copy.
4. Your numbers
You type the costs, yields, prices, and customer details. You are responsible for whether those numbers are true. KamraiDee is a calculator and a book, not an accountant, not a tax advisor, not a lawyer. A sell price the app shows is not a promise that you will keep that profit.
If you type another person’s name or phone (a shop customer, a teammate), you must have a lawful reason. Do not upload illegal content, other people’s secrets, or data about children.
5. Plans and money
Paid plans are not on sale during the public beta. Prices are shown for reference.
Free ฿0. Plan details are on /pricing. Same prices for every pack. Plans change extras and limits, not the costing math.
We charge in Thai baht (THB) only. If the site shows a price in another currency, such as MYR, SGD or USD, that price starts with "About". It is a guide only. When you pay, you pay in THB. Your bank or card provider sets the exchange rate and any fees.
During the beta we do not take card payments. If you choose a paid plan, you pay by PromptPay or bank transfer to the company account shown at checkout, and send the slip. Our team checks it by hand and turns the plan on. Plans are prepaid for the period you choose. They do not renew automatically. When the period ends, the shop moves back to Free and keeps its data. Payments are not refunded, except where Thai law requires it. We never ask you to pay by chat message.
If an affiliate program is on, the rate and period shown in the app at that time apply. Commission is on paid Basic, Pro and Elite plans and paid extensions. There is no commission on the Free plan or on Supplier Corner ads.
6. Public pages
A public shop at /m/your-handle shows what you publish. Treat that page as public on the internet. Public tools do not save a shop profile from the numbers you type. Do not paste other people’s personal data into a public tool.
PromptPay on a thank-you page is a bank rail you show your customer. We do not operate PromptPay.
7. Acceptable use
- Do not break the law with the service.
- Do not attack, scrape, or overload the site.
- Do not try to open another shop’s workspace.
- Do not pretend KamraiDee is only for one kind of shop, or use our name on a product we did not make.
We may suspend or delete a workspace that breaks these rules, with or without notice in serious cases.
Features may appear, hide, or change. We do not promise a particular uptime. We may take the service down to fix it.
We own the software, the mark, and the site design. You keep the content you type. You give us a licence to host that content so the product can run.
8. Liability
The service is provided as it is. To the extent Thai law allows, we are not liable for lost profit, wrong cost numbers, downtime, or data you did not export. Nothing here limits liability that Thai law does not let us limit.
9. Law and changes
These terms follow the law of Thailand. Courts in Thailand have jurisdiction, unless a mandatory consumer rule says otherwise.
We will change this page when the product, billing, or the law changes. The date at the top will move. A material change also gets a short note in the product where we can reach you.
