Last updated: September 2026

Summary

VoltLab does not collect personal data. We do not require accounts, do not place tracking cookies, and do not run third-party analytics scripts (no Google Analytics, no Facebook Pixel). All calculations run entirely in your browser — your inputs never leave your device.

Data We Do NOT Collect

Data We Do See (Server-side)

Our hosting provider (Cloudflare) may log basic request metadata (IP address, user-agent, requested URL) for security and abuse prevention. This data is retained for a maximum of 30 days and is not linked to any user profile. See Cloudflare's privacy policy.

Cookies

We use only first-party, functional cookies if at all (e.g., to remember dark-mode preference). We do not use cookies for advertising or cross-site tracking.

Advertising (Google AdSense)

We display ads served by Google AdSense. Google may use cookies to serve ads based on your prior visits to this site or other sites. You can opt out of personalized advertising by visiting Google Ads Settings.

Google, as a third-party vendor, uses cookies to serve ads on our site. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and other sites on the Internet.

Children's Privacy

This site is not directed to children under 13. We do not knowingly collect any information from children.

Changes to This Policy

We may update this policy from time to time. The "Last updated" date at the top will reflect any changes. Continued use of the site after a change constitutes acceptance of the revised policy.
