你好，我是 Aster——EasyCalc 的创建者和维护者。我住在中国南方的一个城市，是一名以交易为生的独立交易者，也是一位热爱编程的业余开发者。
EasyCalc 的初衷很简单：市面上有太多计算器要么塞满广告，要么操作繁琐，要么只支持单一语言。我希望做一批干净、快速、同时服务中文和英文用户的计算工具——不需要注册，打开即用。
我的职业生涯围绕金融市场展开。多年来，我每天与数字、图表和概率打交道，逐渐形成了对“精确计算”的依赖和偏好。交易教会我两件事：第一，细节决定成败，一个小小的计算误差可能带来巨大的代价；第二，最好的工具往往是那些最简洁的——它们不喧宾夺主，却在你需要时可靠地运转。
工作之余，我喜欢把日常遇到的计算需求变成一个个小工具。最初只是写给自己用的脚本——比如快速算一下税后工资，或者估算复利收益。后来朋友们开始使用，反馈出乎意料地好。于是 EasyCalc 诞生了。
隐私优先。所有计算都在你的浏览器本地完成，数据不会上传到任何服务器。你输入的身高体重、薪资数字、投资本金——这些信息只属于你自己。
双语言平等。无论你使用中文还是英文，每个工具都有完整的双语版本。我不希望语言成为获取实用工具的障碍。
简洁干净。目前 EasyCalc 没有放置任何第三方广告，也不追踪用户行为。我尽最大努力让页面保持清爽，让计算本身成为唯一的焦点。
这个网站完全由纯静态 HTML、CSS 和 JavaScript 构建。没有后端框架，没有数据库，没有复杂的前端构建工具。每个计算器都是一个独立的 HTML 文件，加载迅速，逻辑透明。选择这种“极端简单”的技术栈，一方面是因为它足够可靠——服务器只需要分发文件，几乎不会出故障；另一方面，这也意味着任何懂前端的人都可以查看和验证这里的代码。
EasyCalc 会持续增加新的工具和深度科普文章。如果你有希望看到的计算器类型，或者发现某个工具可以改进，欢迎随时告诉我。这个项目的方向很简单——做出更多让普通人生活更方便的工具。
如果你有建议、反馈，或者只是想打个招呼，可以通过以下方式联系我：
Email：futa404@gmail.comHi, I'm Aster — the creator and maintainer of EasyCalc. I live in a city in southern China, make a living as an independent trader, and build simple online tools in my spare time.
The idea behind EasyCalc is simple: too many online calculators are cluttered with ads, cumbersome to use, or only available in one language. I wanted a collection of tools that are clean, fast, and work for both Chinese and English speakers — no registration required, just open and use.
My professional life revolves around financial markets. Years of working with numbers, charts, and probabilities have ingrained in me a deep appreciation for precision and simplicity. Trading taught me two things: first, details matter — a small calculation error can be costly. Second, the best tools are often the simplest — they don't try to impress, but they work reliably when you need them most.
In my free time, I enjoy turning everyday calculation needs into small web tools. What started as personal scripts — quickly estimating after‑tax salary or compound returns — gradually grew into EasyCalc after friends began using and appreciating them.
Privacy first. Every calculation runs locally in your browser. Your height, weight, salary, or investment data never leaves your device.
Bilingual by default. Every tool is available in both Chinese and English. Language shouldn't be a barrier to accessing useful tools.
Clean and simple. Currently, EasyCalc displays no third‑party advertisements and does not track user behavior. The focus is on keeping pages clean so the calculation itself remains the center of attention.
This entire site is built with static HTML, CSS, and vanilla JavaScript. No backend frameworks, no databases, no complex build pipelines. Each calculator is a standalone HTML file — fast to load and transparent in logic. I chose this deliberately minimal tech stack for its reliability: the server simply serves files, which means very little can go wrong. It also means anyone with front‑end knowledge can inspect and verify the code.
EasyCalc will continue to grow with new tools and in‑depth guides. If you have a calculator you'd like to see, or if something could be improved, please reach out. The direction is simple — build more tools that make everyday life a little easier.
