About
What this site is for and how its tools are built: calculators, word tools and games researched from official sources and written for seven languages.

Who runs EasyToolbox
EasyToolbox is designed, built and maintained by Muhammad Abdullah Awais, a full stack developer. Every tool on the site, and every figure or word list it relies on, is checked by Muhammad Abdullah Awais against its sources before it is published.
Each tool page names who built it and checked its sources, next to the date of that check, so the name and the date travel with the figures.
Why the site exists
Most online calculators give a number and nothing else. This site is built on the idea that a figure is only useful when you can see where it comes from: which law sets the rate, which formula produces the result, and when it was last checked.
That is why each tool page lists its sources and shows the date its figures were checked. Where a source fixes an answer, the page also works through those cases under Checked against known answers.
Each tool is written for its own market and in its own language, with that country's rules, vocabulary and currency, rather than translated from English.
How the tools are built
Every tool follows the same four rules, so each figure can be traced to its source and checked.
- Every rate, threshold and legal limit lives in one data file per tool, with the date it was verified.
- The calculator, the worked examples and the tables on each page are all generated from that file, so they cannot disagree.
- Automated tests check every formula against reference values, and a page that fails them is not published.
- Every tool, from the calculators to the word tools and games, runs in your browser, so nothing you enter is sent anywhere.
The methodology page describes each step in full.
How the figures stay current
Each tool's data file records when its figures were checked, and most also record the date by which they must be checked again. Rates, thresholds and allowances change with budgets, new tax years and new regulations. A figure that was right when it was published will not stay right on its own.
An automated test fails once a recheck date has passed, and the site cannot be built again until the figures behind it have been looked at. An outdated figure therefore cannot sit on a page unnoticed.
When a law changes, for example with new rates for the coming year, the new figures are checked at the source before they reach the data file. The date on each tool page says when that check last happened.
Word tools and games
The word tools, from the Wordle solver to the word unscrambler and the noun gender checker, work from open word lists and dictionaries that anyone may reuse. Each tool page names the lists it relies on, and the licence file published with the lists gives every origin, attribution and licence.
The games and tests, such as the Ten Tangle daily word scramble, the flag quiz and the click speed test, run entirely in your browser and need no account. Where a game keeps scores, statistics or a game in progress, it keeps them only in your browser's local storage, and several games keep nothing at all. The cookie policy lists every entry and what it holds.
One site, one address
EasyToolbox is published at EasyToolbox.org in seven languages: English, German, Spanish, French, Italian, Dutch and Polish. Each language version follows its own country's rules rather than a translation of another. Other sites with a similar name are not connected to this one.
The tools are grouped into categories, such as finance, automotive, cooking and word games, and the list of all tools shows every one of them in a single place.
What the site does not claim
The pages are research and software work, not professional advice. No tax adviser, lawyer or financial adviser has reviewed them, and every result is an estimate for information. The disclaimer sets out what that means, and the developer page describes how each figure is researched.
When a rule is unclear or a source is silent, the page says which reading the tool uses instead of presenting it as settled.
Independence
The site is free. It is not paid by any lender, bank or product provider and has no affiliate links. If advertising is added in future, it will be clearly separated from the tools and will never influence a result.
There are no accounts, no paid features and nothing to sign up for, so every tool is available in full to every visitor.
Corrections and suggestions
Errors and suggestions are welcome through the contact page, which explains what a useful report contains and what happens after you write. An idea for a new tool is welcome in the same way, ideally with the question it should answer and the country it is for.
A confirmed error is corrected in the tool's data file, so the calculator, the examples and the tables change together. The date on the page is then updated to show the new check. The methodology describes how figures are sourced, tested and dated, before and after a correction.
