About — zUnits

zUnits is a set of fast, free online unit converters for length, weight, temperature, volume, and area, available in English, Arabic, Spanish, and Portuguese.

The site is built to be light and simple: pages load in a single request, work on any device, and keep working offline after your first visit.

Terms

zUnits is free to use for any personal or commercial purpose.

The conversion results are provided for general information. We work hard to keep the factors exact, but we give no warranty, and you should double-check any value used for engineering, medical, legal, or commercial decisions.

Privacy

zUnits is committed to protecting your privacy and ensuring a transparent, secure online experience. We do not ask for, collect, process, or store any personal information, and no account registration or sign-in is required to use any of our unit conversion tools.

To provide fast loading speeds and offline functionality, pages and conversion data may be saved in your browser's local cache or service worker storage. All such data remains strictly on your local device, is never transmitted to our servers, and can be cleared at any time through your browser settings.

Like most standard web servers and content delivery networks (CDNs), basic anonymous technical data—such as browser type, device category, language preference, and timestamps—may be temporarily processed in server logs for system maintenance, performance optimization, and security against cyber threats. This data is aggregated and is never linked to individual identities.

We do not use invasive tracking cookies, cross-site trackers, or sell user data to third-party advertisers or data brokers. If third-party services, analytics, or advertising partners (such as Google AdSense) are incorporated in the future, this policy will be updated immediately to outline their cookie usage and your privacy choices.

By using zUnits, you consent to this privacy policy. If you have any questions, concerns, or inquiries regarding data privacy or security, please feel free to reach out to us via our contact information below.
