NerdVolt is a public information site. You do not need an account to read guides, calculators, news explainers, or policy pages, and calculator inputs are processed entirely in your browser — they are not sent to NerdVolt's servers.
Publisher and site operator
This site is operated by NerdVolt, the publication's public operating identity. NerdVolt does not currently name a separate legal entity or an individual privacy officer on the site. Privacy questions and requests should be sent to editor@nerdvolt.com, which is the accountable contact for editorial, correction, and privacy matters.
What this site currently collects
Because this is a static, self-hosted site, the current data surface is intentionally small:
- Server and security logs. When you request a page, the web server records basic request data: the page requested, your IP address, browser type and version, operating system, approximate location derived from the IP address, referring page, and the time of the request. These logs are used to keep the site working, diagnose errors, and detect abuse. Logs are rotated daily and retained in compressed form for approximately 14 days.
- Contact and corrections messages. If you email NerdVolt, the message may include your email address, the page URL, and any details you choose to provide. That information is used only to respond to and evaluate your request, and it is not sold or shared for advertising.
NerdVolt does not currently operate analytics scripts, does not set cookies itself, does not load external fonts or embeds, and does not use advertising cookies, because no advertising service is currently enabled on the site. Calculator inputs, saved preferences, and results stay in your browser.
Advertising and Google services (applies when advertising is enabled)
NerdVolt is publisher-funded and may display advertising in the future. The following disclosures describe the advertising technologies the site is configured to support. They take effect only when advertising is enabled; if no advertising is displayed to you, the advertising cookies described here are not placed.
If advertising is enabled, NerdVolt may use Google AdSense and related Google advertising technologies. Google and its approved third-party advertising vendors may place or read cookies, and may use IP addresses, web beacons, and similar identifiers, as part of ad serving, frequency capping, and measurement.
Personalized and non-personalized advertising. Google may show personalized ads based on information such as your prior visits to this and other sites. Where the law requires consent for personalized advertising, NerdVolt will request that consent first, and you may instead receive non-personalized advertising, which is targeted only by general location and the content of the page. Non-personalized ads still use cookies or similar identifiers for frequency capping, aggregated reporting, and fraud protection.
How Google uses information from partner sites and apps. Google's advertising systems may combine information about your visits to this site with information from other sites and apps that use Google's advertising services, as described in Google's "How Google uses information from sites or apps that use our services" page. That page describes how Google uses data, how you can control it, and how Google's use is governed by its privacy policy.
Third-party advertising vendors. Google may share ad-serving identifiers with approved third-party vendors and technology providers. The current list of Google-certified vendors is available through Google's advertising controls and consent platform, and NerdVolt's consent tooling will present vendor information where required.
Advertising and privacy settings available to readers. You can control personalized advertising through Google Ads Settings, the About Ads opt-out, and the Network Advertising Initiative opt-out. These controls are operated by Google and by the advertising industry, not by NerdVolt.
Consent choices
When advertising is enabled, visitors in the European Economic Area, the United Kingdom, and Switzerland will be asked for consent through a consent-management platform before non-essential advertising cookies are placed, using the Google-supported transparency and consent framework. Visitors in applicable United States states will be offered privacy choices, including the choice to opt out of the "sale" or "sharing" of personal information as those terms are defined by applicable state law, through a "Do Not Sell or Share My Personal Information" control.
You can review, change, or withdraw consent at any time on the Privacy Choices page, which is linked in the footer of every page. Withdrawing consent does not break the site: essential functions, calculators, and reading remain available without advertising consent.
NerdVolt does not sell personal information in the ordinary commercial sense. NerdVolt does not sell data it collects (such as server logs or contact messages) to third parties. Where personalized advertising is enabled, advertising identifiers shared with Google and its vendors may qualify as a "sale" or "sharing" of personal information under the California Consumer Privacy Act (as amended by the California Privacy Rights Act) or similar state laws. If you are in a state that provides such rights, you can opt out of that advertising-related "sale" or "sharing" through the Privacy Choices page. NerdVolt does not knowingly "sell" or "share" the personal information of consumers under 16.
European privacy rights
If you are in the European Economic Area, the United Kingdom, or Switzerland, you have rights under the GDPR and related national laws, including the rights to access, rectify, erase, restrict, and object to processing, and to data portability, subject to legal limits. To exercise these rights, contact editor@nerdvolt.com with the page or issue involved. NerdVolt will respond within the timeframes required by law. There is no fee for a reasonable request, and you also have the right to lodge a complaint with your local supervisory authority.
United States state privacy rights
Residents of states with comprehensive privacy laws (including California, Colorado, Connecticut, Utah, Virginia, and others as they take effect) may have rights to know what personal information is collected, to access and delete it, to correct it, and to opt out of "sale", "sharing", or targeted advertising. NerdVolt's data practices are described on this page, and the Privacy Choices page provides the opt-out controls where they apply. NerdVolt does not use the personal information it collects for profiling that produces legal or similarly significant effects.
Data retention and security
Server logs are retained approximately 14 days and are accessible only to the site operator and hosting administrator. Contact messages are retained only as long as needed to handle your request. The site is served over HTTPS, and the operator follows standard hosting security practices. No data processing system is completely secure, and NerdVolt cannot guarantee absolute security.
Children's privacy
NerdVolt is not directed to children under 13, and it does not knowingly collect personal information from children. If you believe a child has provided personal information, contact editor@nerdvolt.com and NerdVolt will remove it where required by law.
External links and policy changes
Pages link to external sites (manufacturers, utilities, agencies, standards bodies). Those sites have their own privacy practices, which NerdVolt does not control. This policy may be updated as the site's services change; the "Effective date" and "Last updated" fields below will always show the current version.
Effective date and last updated
Effective date: August 14, 2026. Last updated: August 14, 2026.
