What We Collect

VoltCalcs collects minimal data. All calculator computations run entirely in your browser — we never see your inputs or results.

Google Analytics 4

We use Google Analytics 4 (GA4) to understand how visitors use the site — which pages are popular, how long people stay, and where traffic comes from. GA4 collects anonymised usage data including page views, session duration, approximate location (country/city level), device type, and browser.

GA4 scripts only load after you explicitly accept cookies via the consent banner. If you reject cookies or never respond to the banner, no analytics data is collected from your visit.

Cookies

We use one first-party cookie: cookie_consent, which stores your cookie preference (accepted or rejected). This cookie expires after 365 days.

If you accept cookies, GA4 sets additional cookies for analytics purposes. You can change your preference at any time via the "Cookie Settings" link in the footer.

Contact Form

The contact form collects: your name (optional), email (optional), message category, and message text. This data is sent via Resend (our email delivery service) to our inbox. We do not store form submissions in a database — they exist only as emails.

The form uses Cloudflare Turnstile for bot protection. Turnstile may set a cookie to verify you are human but does not track you across sites.

Rate Limiting

We use Upstash Redis to rate-limit contact form submissions (3 per IP address per hour). Your IP address is used only for rate limiting and is not stored permanently.

Third-Party Services

  • Google Analytics 4 — website analytics (consent-gated)
  • Cloudflare Turnstile — bot protection on forms
  • Resend — transactional email delivery
  • Upstash Redis — rate limiting
  • Vercel — website hosting

Your Rights

Under GDPR, you have the right to access, correct, or delete any personal data we hold. Since we store minimal data (only the consent cookie and any emails you send us), you can exercise these rights by emailing contact@voltcalcs.com or using the contact form.
