Terms of Use

Every tool is free to use, with no account and no usage limit. You do not need our permission to use a result in your own work, personal or commercial. There is nothing to attribute and nothing to pay.

Every tool ships with automated tests that check its calculations against known values, and those tests run before any change goes live. We take correctness seriously.

Even so, the tools are provided “as is”, without warranty of any kind. We do not guarantee that a result is accurate, complete, or suitable for your particular situation, and we are not liable for any loss arising from relying on one. Check anything that matters — see the disclaimer for what this means for financial and health tools specifically.

You agree not to:

• Attempt to disrupt, overload or break the site or its hosting.
• Scrape the site at a volume that degrades it for other people.
• Republish the site wholesale as your own, or present it as operated by you.
• Use it for anything unlawful.

Reasonable, ordinary use is welcome, including linking to any tool from anywhere.

We aim to keep the site up, but we do not promise uninterrupted availability. Tools may be changed, renamed or removed. Because everything runs in your browser, a tool you have open keeps working even if the site goes down mid-session.

The tools are free and account-free. Display advertising is planned to support the site; AdSense approval is pending. Any future ads will use clearly marked slots and will not gate a result behind a click or a wait.

The site’s design, text and code belong to Sujit Maharjan. The results you generate are yours. Third-party trademarks mentioned in tool descriptions belong to their respective owners and are used only to describe what a tool does.

These terms may be updated as the site changes. The date at the top shows when they last did. Continuing to use the site after a change means accepting the updated terms.

These terms are governed by the laws of Nepal, and any dispute is subject to the courts of that jurisdiction.
