About Me & This Calculator

Hi there! Let me tell you a bit about myself and why I built this tool.

Why I Built This

I'm a developer who got frustrated with existing percentage calculators. They were either cluttered with ads, required accounts, or just didn't work well. So I decided to build my own - the calculator I always wanted to use.

My philosophy is simple: useful tools should be free, fast, and respect your privacy. That's why everything runs locally in your browser - I literally can't see what you're calculating, even if I wanted to (which I don't).

How I Built It

I used Next.js 14, TypeScript, and TailwindCSS to create something that's both beautiful and functional. The dark mode toggle? That's because I'm a night owl and hate bright screens at 2 AM.

Every feature I added is something I actually use. The history? Because I always forget what I calculated 5 minutes ago. The export? Because sometimes you need to share results with colleagues.

Lightning Fast

I optimized every calculation to be instant. No waiting, no loading spinners.

100% Private

Your data never leaves your device. I built it this way because that's how I want my tools to work.

Smart History

Tracks your calculations locally so you can reference them later. Export when you need to.

My Promise to You

I built this calculator to be genuinely useful, not to collect data or show ads. It's completely free and always will be. If you find it helpful, that's all the reward I need.

Have suggestions or found a bug? I'd love to hear from you! I'm always looking to improve the tool based on real user feedback.
