About Kitsaku
Kitsaku is a collection of small, free web apps for everyday things. Each one does a single job, works right in your browser, and doesn't ask you to sign up or install anything.
Who runs Kitsaku
Kitsaku is made by Yosua, an independent developer in Jakarta, Indonesia. Contact: hello@kitsaku.com.
Why it exists
Plenty of everyday questions have answers that are easy to calculate but tedious to work out by hand, like how many miles a credit card really earns for the way you spend. Kitsaku gathers small tools that answer questions like these quickly and clearly, in several languages.
The apps run in your browser. What you type stays on your device and isn't sent to Kitsaku. Some apps remember your settings in your browser so they're there next time. See the Privacy Policy for details.
How it stays free
Kitsaku is paid for by ads, shown below or beside an app and never inside it. Some pages may also have affiliate links: if you click one and then sign up or buy, Kitsaku may earn a commission, at no extra cost to you. Affiliate links are always labelled, and they never change what an app calculates. Read more in the Terms of Use.
Results from the apps are estimates. Always check the official source before you book, buy or decide anything. See the disclaimer.
