Hey ProductHunt! 👋 I'm Abu Quatada, and I built ZMPL Tools after getting frustrated with every free tool in India either asking me to sign up or quietly tracking what I typed. I'm a developer from Bhopal, India and I wanted simple, fast, private tools for the things I calculated every week — my GST, my home loan EMI, and my age for a government form. So I built 6 tools that run completely in your browser. Your GST inputs, your loan numbers, your text — none of it ever reaches our servers. Not because of a privacy policy promise — because the architecture makes it impossible. Today I'm launching all 6: GST Calculator, EMI Calculator, Age Calculator, Percentage Calculator, Word Counter, and Grammar Checker. I'd love your honest feedback — especially: — Which tool did you find most useful? — Is there a 7th tool you'd want for India? — Is there anything broken on mobile? Thank you for taking the time to check it out. Every comment genuinely helps a solo indie developer from India. 🙏
