Values entered into our calculators and converters are processed locally in your web browser. We do not transmit or store those values on our servers. Avoid entering sensitive personal information into any online form unless it is necessary and you trust the service.
Information collected automatically
Like most websites, our hosting provider may process limited technical information needed to deliver and secure the site, such as an IP address, browser type, requested page, approximate region, timestamp, and security events. Server logs are used for reliability, abuse prevention, and troubleshooting and are retained only as reasonably necessary for those purposes.
Analytics and cookies
We may use analytics to understand aggregate page usage, device categories, and site performance. Analytics providers may receive page and device information and may use cookies or similar identifiers, subject to applicable choices and controls. Essential storage may be used for security or to remember a preference you request. Where non-essential analytics requires consent, it will be used only after the required choice.
Advertising
We may display advertising, including through Google AdSense. Third-party vendors, including Google, may place and read cookies in your browser or use web beacons, IP addresses, and similar identifiers because ads are served on this website. These technologies can deliver and measure ads, limit repetition, detect fraud, and—where permitted—personalize advertising.
Google explains how it uses information from sites that use its services in its partner sites policy. Users can manage ad personalization through My Ad Center and browser controls. Where consent is legally required, eligible advertising technologies will be used only after the required choice.
Contact messages
If you email us, we receive the address and information you choose to send. We use it to respond, investigate reports, and maintain a reasonable record of the exchange. Do not send sensitive personal data. We do not sell contact information.
Sharing and retention
We may share limited information with service providers that host, secure, analyze, advertise on, or support the website, subject to appropriate restrictions. We may also disclose information when legally required or to protect rights and safety. Information is retained only as long as needed for the stated purpose, legal obligations, dispute resolution, or security.
Your choices and rights
You can block or delete cookies using your browser, use privacy controls offered by analytics and advertising providers, and contact us about access, correction, deletion, objection, or other rights that may apply in your jurisdiction. Some requests require verification. Email privacy questions to privacy@numutility.com.
