Last updated: June 2026. This policy describes how voltdropcalc.com ("we", "this site") handles information.
All calculations run locally in your browser. We never see the values you enter, and saved projects (where offered) live in your browser's localStorage only. We do not require accounts and do not collect names, emails or payment details.
We use Google Analytics 4 to understand aggregate usage — pages visited, approximate region, device type. GA4 sets cookies and collects pseudonymous identifiers. Where required, analytics runs only after consent (Google Consent Mode v2). Google Analytics collects anonymized usage data (pages viewed, approximate region, device class); you can opt out entirely with the GA opt-out browser add-on.
This site is supported by advertising and may serve ads through Google AdSense, Ezoic and/or Adsterra. These networks may use cookies and similar technologies to serve and measure ads, including personalized ads where you have consented. You can manage personalization at Google Ads Settings or opt out of many partners at aboutads.info. Network policies: Google AdSense · Adsterra · Ezoic. Adsterra and Ezoic are independent third-party networks; ads they serve may set their own cookies under their own policies.
Cookies on this site come from the analytics and advertising services above. You can block or delete cookies in your browser; the calculators work fully without them.
Depending on your region (GDPR, CCPA and similar), you may have rights to access, delete or object to processing of personal data held by the services above. Requests about this site itself can be sent to contactus@voltdropcalc.com.
We may update this policy as the site evolves; the date above reflects the latest revision.
