Terms of Use

These terms govern your use of w3htech.com and the free tools, calculators, and blog it hosts (together, the "Site"). By using the Site, you agree to these terms. If you don't agree, please don't use the Site.

Free to use

The Site is provided free of charge, without accounts, sign-ups, or payment. There is no subscription, license fee, or paid tier.

"As is", no warranty

The tools and calculators on this Site are provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, reliability, or fitness for a particular purpose. In particular:

• Astrology and panchangam calculators (moon phase, sunrise/sunset, Rahu Kaalam, Tithi, Nakshatra, zodiac compatibility, numerology, and similar) are provided for informational and entertainment purposes only and are not professional, medical, financial, legal, or astrological advice.
• General calculators (EMI, BMI, energy usage, unit conversion, and similar) are aids for estimation only and should not be relied on as the sole basis for financial, health, or engineering decisions.
• Developer and network tools (formatters, generators, lookups, testers, and similar) are provided for convenience; always verify results before relying on them in production systems.

Your data and content

Most tools process your input entirely in your browser and never send it to our servers (see our Privacy Policy for details on the few that do). You are responsible for backing up anything you create with these tools — for example, whiteboard drawings or generated files — since data kept only in your browser's local storage can be lost if you clear your browser data or switch devices.

Acceptable use

You agree not to misuse the Site — for example, by attempting to disrupt its availability, probing it for vulnerabilities without authorization, or using any tool to violate applicable law or the rights of others.

Third-party services

Some tools rely on third-party services (such as public DNS-over-HTTPS or WHOIS APIs) that are outside our control. We aren't responsible for the availability or accuracy of those third-party services.

Limitation of liability

To the fullest extent permitted by law, W3HTech is not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the Site or any tool on it.

Changes

We may update these terms or any tool on the Site at any time. Continued use of the Site after changes are posted means you accept the updated terms.
