Terms of Service

Introduction

Welcome to DelightfulDev (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of delightfuldev.com and all of its front-end developer utilities, guides, and related features (together, the “Service”). By using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

Acceptance and Changes

By accessing or using DelightfulDev, you confirm that you have read and accept these Terms and our Privacy Policy, which forms part of them. We may update these Terms at any time; continued use after a change means you accept the current version.

Convenience Tools, Not Professional Advice

The Service exists to give general, educational estimates that speed up front-end work. The unit, colour, aspect-ratio, contrast, viewport, and clamp() tools apply standard formulas to the values you enter; their results are authoring aids, not professional design, engineering, or accessibility advice, and not a guarantee of any outcome. DelightfulDev is not a design agency, an accessibility auditor, or a standards body. Anything with real consequences — especially an accessibility requirement you are obliged to meet — should be verified in a real browser and, where it matters, with a qualified specialist rather than this Service.

What the Service Provides

DelightfulDev offers, free of charge:

• A px, rem & em unit converter
• A hex, RGB & HSL colour converter
• An aspect ratio calculator
• A WCAG contrast ratio checker
• A viewport units calculator, and a fluid CSS clamp() generator
• Educational guides, a Learn section, and an illustrated Web & Computing Museum

We may modify, suspend, or discontinue any part of the Service at any time.

Your Responsibilities

When you use the Service, you agree to:

• Use the tools in good faith for your own development work
• Enter accurate values, and check units, font-sizes, and viewport figures before relying on a result
• Verify anything that must be correct — contrast, layout, and computed styles — in a real browser
• Not attempt to disrupt, overload, scrape, or reverse-engineer the Service
• Not use the Service for any unlawful purpose or to infringe others’ rights

No Warranty

The Service is provided “as is.” While we aim for accuracy, we make no warranties, express or implied, that calculations are error-free or fit for your particular purpose, and we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Limitation of Liability

To the fullest extent permitted by law, DelightfulDev and its suppliers will not be liable for any damages — including lost work, loss of data, or any harm arising from a design or accessibility decision — arising from your use of, or inability to use, the Service, even if advised of the possibility of such damage.

Intellectual Property

The site’s original text, design, and tool code are the property of DelightfulDev and protected by copyright. Museum and Learn material sourced from Wikipedia and Wikimedia Commons remains under its original licenses. You may use the tools for personal and professional development work; you may not copy or repurpose the site’s materials for commercial redistribution without permission.

Third-Party Links and Advertising

The Service may link to third-party sites and displays advertising through networks such as Google AdSense. We do not control or endorse third-party content, and using any linked site or advertised product is at your own risk.

Governing Law

These Terms are governed by the laws of the United States, and you submit to the courts of that jurisdiction for any dispute.
