Syedali Mallikar

Founder & Editor-in-Chief

Syedali Mallikar is a software developer and lifelong learner who founded ichihu in 2026 with one goal in mind: build free, no-nonsense online calculators that actually work. After years of using cluttered, ad-heavy tool sites that demanded signups for simple math, he decided to build something better — tools that load fast, respect user privacy, and give you a clear answer without any friction.

When he's not building tools or reviewing formulas, Syedali writes about productivity, personal finance, and the small systems that quietly make life easier. He believes that good software should feel invisible — you open it, use it, close it, and get on with your day.

What Is ichihu?

ichihu is a free online calculator platform for health, fitness, finance, and productivity. Every tool on this site does one job well: it takes a few numbers you already know, runs them through a well-established formula, and gives you an answer in seconds.

We currently offer 17 free calculators covering the essentials of everyday planning:

Every calculator is completely free. No trial periods, no premium tier, no "unlock the answer" walls, no email list to join. If it takes more than 10 seconds to use, we've done something wrong.

Our Mission

The internet is full of calculator sites. Most of them share the same problems: aggressive ads, pop-ups before you can read the answer, forced account creation, and — worst of all — formulas that are either outdated or just plain wrong.

We built ichihu to be the opposite of all that.

That means three things:

• Accuracy first. Every formula is verified against primary sources — clinical research, government health organizations, financial industry standards, or established academic references.
• Speed matters. Our pages load in under a second on most connections. The calculator is always above the fold. You get your answer without scrolling past five ad units.
• Privacy respected. All calculations run in your browser. Your numbers never leave your device. We don't sell data, and we don't track you across the web.

Editorial Standards & Accuracy Policy

Every calculator on ichihu goes through the same review process before it's published. We take this seriously because people use our tools to make real decisions about their health, money, and time.

• 1. Verified formulas Every formula is checked against at least two independent sources — typically a peer-reviewed study, a government agency (CDC, WHO, NHS, IRS, etc.), or a well-established textbook. If formulas disagree, we use the most widely accepted one and disclose alternatives.
• 2. Manual calculation tests Each calculator is tested against hand-calculated examples across a range of inputs — including edge cases like zero, negative, and very large numbers — before being published.
• 3. No AI-generated content Our articles are written or reviewed by a human editor. We do not publish AI-generated articles or AI-written calculator explanations. If AI tools are used at all, it's only as a research aid — never as the published output.
• 4. Regular updates Financial formulas, tax brackets, contribution limits, and health guidelines change over time. We review and update our calculators whenever the underlying standard changes.
• 5. Corrections policy If you find an error, tell us. We fix it within 48 hours of verification and credit the reporter on the page. Email contact@ichihu.com with the details.
• 6. Medical & financial disclaimers Every health and finance calculator displays a clear disclaimer. Our tools are for general information and educational purposes only — they are not a substitute for professional medical, financial, or legal advice.

Privacy & How We Handle Your Data

Privacy isn't a feature we bolted on later — it's the foundation of how ichihu works.

• Your inputs stay on your device. Every calculation runs in JavaScript inside your browser. We never see your weight, income, age, or any other number you type.
• No account required. You'll never be asked to sign up, log in, or verify an email to use a tool.
• No tracking pixels across sites. We don't use Facebook Pixel, TikTok Pixel, or any other cross-site tracking technology.
• Minimal analytics. We use privacy-friendly analytics to understand which tools are popular and how to improve them. We don't build user profiles or sell data.
• No selling data. Ever. To anyone. For any reason.

Advertising Disclosure

ichihu is free to use and always will be. To cover hosting, development, and content costs, we display advertising through third-party ad networks. Here's what that means for you:

• Ads are clearly marked as ads and never disguised as site content.
• Advertising partners may use cookies to display relevant ads based on your browsing history. You can control this in your browser settings or via ad network opt-outs.
• We do not allow ads to interfere with calculator functionality. Your results are never hidden behind ads.
• Editorial content is never influenced by advertisers. Advertisers have no input into what we publish.

We believe free, honest advertising is a fair way to keep the site running without charging users. If you'd like to support us in other ways, simply sharing our tools with someone who needs them is the best thing you can do.
