I’m Kailash Choudhary, and I run Mubarak4u from Makrana, Rajasthan. You can write to me at kailsh94136@gmail.com or use the form on this page.
When you can write to me
- You found a wrong result in a calculator or converter.
- A tool has a problem, such as a button that doesn’t work or a page that doesn’t load.
- You found a mistake or old information in a tool explanation.
- You want to ask for a new tool.
- You have feedback that can make the website easier to use.
How to report a problem
To help me fix it fast, please include:
- The link of the tool page
- The numbers or text you entered
- The result you got and the result you expected
- Your browser and device, for example Chrome on Android
Please don’t send passwords, ID numbers or private files. The tools work in your browser, so I never need them.
When you report a wrong result, I check it against the formula or the official source, fix the page and update its “Last updated” date.
Suggest a new tool
Tell me what the tool should do, what a visitor will enter and what result they should get. I read every suggestion, but I can’t promise to build every tool.
What I can’t help with
Calculator results are estimates. I can’t give personal financial, legal or tax advice by email. For an exact figure, check with your bank, your lender or a qualified professional.
Response time
I try to reply to genuine emails within 2 working days. It can take longer when I get many messages.
You can also read more about me and how I handle your data in the Privacy Policy.
Email us
Send your message to kailash94136@gmail.com.
Please write the name of the tool in the subject line, for example “Land Area Converter result problem”.
