Terms of use

Using the tool

ExactHex is run by Md. Delwar Hossen, an independent developer. Everything on this site is free to use, for personal work and commercial work alike. There is no account to create, no license key, no usage cap and no attribution requirement. Using the site means you accept what is written on this page.

Your images stay yours

You keep every right you already had in any image you open here. Nothing on this site claims ownership of your files, and in practical terms it could not: your images are never transmitted, so they are never received. The privacy policy explains the mechanics.

It follows that you are responsible for having the right to use whatever you open. That matters most for the URL field: pasting the address of an image causes your browser to fetch it from its host, and whether you are entitled to do that is between you and them.

The colors you take are yours to use

Color values are measurements, not creative works, and no claim is made over anything the tool hands back. Hex codes, palettes, shade ramps, harmonies and every exported file (CSS, Tailwind, SCSS, JSON, hex lists and SVG swatch sheets) are yours to use, change, publish and sell. You do not need to give credit or ask permission.

A color taken from a logo can still be part of someone's trademark or brand identity. This tool can tell you what color something is; it cannot tell you whether you are allowed to use it that way.

What the tool does and does not guarantee

The tool reads the sRGB byte values in an image as your browser decodes it, with no interpolation and no rounding, and that reading is exact. What it cannot guarantee is that those bytes are the color someone originally intended, because compression, anti-aliasing and color profiles all change an image before it reaches you. The field guide measures how much. Read it before you rely on a value.

Specifically, this is not a substitute for a calibrated display, a spectrophotometer or a printed proof. If money or a legal obligation depends on a color, such as brand compliance, a print run or a paint specification, check it in the final medium.

Availability

The site is offered as it is and as it happens to be available. It may be offline for maintenance, features may change, and no promise is made that any particular capability will still be here next year. If something is removed, the reason will be that it stopped working properly rather than that it moved behind a payment.

To the fullest extent the law allows, the tool is provided without warranties of any kind, and Md. Delwar Hossen is not liable for any loss arising from using it or from being unable to use it. That is the usual position for free software.

Fair use of the site

There are no rate limits to trip over, because the work happens on your device rather than a server. What is asked in return is straightforward: do not attempt to break, overload or interfere with the site or anyone else's use of it, do not scrape and rehost it as though it were your own service, and do not use it in the course of anything unlawful.

Linking to any page here is always welcome and needs no permission.

The site itself

The design, written content, illustrations and source code of this site remain the property of Md. Delwar Hossen. You are welcome to quote from the guides with a link back. Republishing whole pages, or shipping a copy of the tool under another name, is not something these terms permit.

Governing law and disputes

These terms are governed by the law of the country where Md. Delwar Hossen lives, without regard to its conflict-of-law rules. If you use the site as a consumer, you keep every protection that the law of your own country gives you and that an agreement cannot take away.

Before taking any formal step over a disagreement, write to info@exacthex.com. Most problems with a free tool can be settled by email.

Changes

These terms may be updated as the tool changes. The date at the top of the page shows when they last were, and the current version is always the one published here. Continuing to use the site after a change means the updated terms apply.

Questions

Anything unclear, email info@exacthex.com and it will be answered directly. If a term here does not fit how you need to use the tool, tell me and I will look at it.
