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. Install the app for offline GST, salary, tax, EMI, and most developer tools — not for SIP charts, PDFs, Markdown, or IFSC. 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. Install covers GST, salary, income tax, EMI, rent receipt, checksum tools, most developer/text pages, and the new India/money calculators. Ctrl/Cmd+K finds tools. SIP charts, PDF libraries, background-remover models, Markdown preview, and IFSC still need the network the first time. CDN libraries are version-pinned with Subresource Integrity.
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.
