Privacy-first utilities
Open a tool. Type. Done.
India GST, salary, and tax calculators, plus EMI, PDF merge, JWT, and word count. Arithmetic stays in this tab. No email wall. Press / to search.
- You type — number, token, or file
- Most sites upload it
- Here it stays in this tab
Ads and analytics only if you consent. Calculator math is never sent to me. IFSC lookups, and a few PDF/chart libraries, still use the network; those pages say so. This is not “100% offline.”
Why it exists
Do the arithmetic. Close the tab.
I built these because GST and salary pages kept asking for an email before they would add two numbers. India calculators are the core: GST, salary, income tax. EMI, PDF merge, JWT decode, and word count sit beside them because I use those weekly. Every result is an estimate, not a filing. If a number looks wrong, use Share feedback. What stays in the tab, and what does not, is on the privacy policy.

Questions I actually get
Is every byte on this domain offline?
No. Ads, analytics, and the consent banner use the network if you allow them. Calculator math never gets sent to us. A few tools load an open-source library or look up a bank code — each of those says so on its own page.
Can I trust the tax figures?
You can read the government link on each India page and check it yourself. You cannot treat a browser estimate as a filing. I am not your CA.
How do I report a wrong number?
Use Share feedback — include the tool URL and what looked wrong. For tax or GST disputes, link the government source too.
