How Our Tools Work and Your Privacy

Our tools process what you enter in your browser using JavaScript. Your text, files and figures are not sent to our servers or stored by us. Read the details in our Privacy Policy.

How We Keep Our Tools Accurate

We check our calculators against standard formulas and worked examples. For tools that depend on rules and rates, such as tax, GST, PPF and FD interest, we show the date we last checked and update them when the rules change. Our calculators give estimates and are not financial, tax or medical advice, as explained in our Disclaimer. If you find a mistake, please tell us.

How the Site Is Supported

WebToolsKit.in is free to use. We pay for hosting through ads and affiliate links. Sponsored links are marked as ads, and they never change the result of a calculation.

Our Story

WebToolsKit began as a personal set of small utilities used during software development. The site is built and maintained by an independent software developer who works with ASP.NET MVC, Angular and APIs. Instead of searching many different websites for small tools, the idea was to keep them all in one place, and then to add the finance and daily-life tools that people ask for.
