Prak Khae is a free calculator built by Ka Vatana, founder of CHNAI LAB, in Phnom Penh. This is version 1. It
has no accounts and no payments, and it keeps none of your data on a server.
What it keeps
The salary you type, your answers about family and work, and your language are kept in your own browser, so
you can come back to the same numbers. They never leave your device.
What it does not do
No accounts. It never asks for a name, a phone number or an email.
No cookies, no trackers and no advertising.
Every calculation runs on your device. Your salary is never sent to us.
Share links
When you press Share, the numbers you typed are written into the link itself, after the # sign. Browsers do
not send that part to a server. Anyone who has the link can read that salary, so send it only to people who
should see it.
The company that hosts the page
The page is hosted on Vercel. As with any website, when you open it the host sees your IP address and browser
type in order to deliver the page. We do not use that data.
