Terms of Use

Last updated: October 20, 2026

These terms cover your use of MakerBox. The tools run on your own machine, and the files you work on are not sent to us. The privacy policy, linked below, sets out what is kept — settings in your own browser, and an email if you write to us.

What the tools are

Every tool here runs in your browser. Your files and text are read by JavaScript on your own device, the work happens there, and the result is returned to you. Nothing is uploaded to us and no server of ours holds a copy. A handful of tools download a large one-off resource the first time you use them — a font, a recognition model — from this site. A few others fetch something from another server to do their job — map tiles, a thumbnail, a larger model, a document at an address you type — and text-to-speech, if you turn its online voices on, sends the words you are converting to Google or Microsoft. Each of those tools says so on its own page, and every one is named, with the server it reaches, in the privacy policy.

No account, no charge

There is nothing to sign up for and nothing to pay. The site is meant to be paid for by advertising. Tools are added, changed and occasionally removed without notice; a tool you rely on today may work differently tomorrow, so keep your own copy of anything that matters.

Your files are yours

You keep every right you had in whatever you open here. We claim nothing, because we never receive it. You are responsible for having the right to use the files you process, and for what you do with the results.

What is not promised

The tools are provided as they are, without warranty of any kind. They are written carefully and tested, and they still may contain mistakes, produce a wrong result, or fail on a file they have not met before. Check anything that matters before you rely on it, and keep the original. This is particularly true of the tools that change a document in place — editing, redacting, compressing — where the output replaces something you cannot get back if you have not kept it.

Nothing here is professional advice. The calculators implement published formulas and are estimates; the health ones in particular are not medical advice, and the financial ones are not financial advice.

To the extent the law allows, we are not liable for loss or damage arising from your use of the site — including lost or corrupted files, or decisions made on a tool's output.

Fair use

Use the tools for anything lawful. Do not use them to process material you have no right to, and do not attempt to disrupt the site for other people. Because everything runs on your own device, there is no rate limit and no daily cap. Tools do have limits of their own — a largest file, a largest picture — and your device's memory sets the rest.

Links elsewhere

Some pages link to other sites. A link does not change what a tool does.

Changes and contact

These terms may change; the date at the top says when they last did. Questions, corrections and bug reports go to eogkr.kim@gmail.com.
