Privacy Policy

Last updated: March 15, 2026

What We Collect

WattCosts collects minimal data to operate and improve the site. Specifically:

Analytics data: We use Google Analytics (GA4) to understand how visitors use the site. This includes pages visited, time on page, device type, browser, approximate geographic location (country and region level), and referral source. Google Analytics uses cookies to collect this information. No personally identifiable information is collected through analytics.

Local storage: When you select your state in a calculator, that selection is saved in your browser's local storage so it persists across pages and visits. This data stays entirely on your device and is never sent to our servers.

How We Use Your Information

Analytics data is used solely to understand which pages and tools are most useful, to identify and fix errors, and to improve the site. We do not sell, rent, or share your personal information with third parties for marketing purposes.

Third-Party Services

Google Analytics (GA4): Provides aggregated website usage statistics. Google's privacy policy is available at policies.google.com/privacy.

Advertising (future): We may display advertisements on this site in the future through an advertising partner. If and when ads are added, this privacy policy will be updated to describe the additional cookies and data collection involved, and a cookie consent mechanism will be provided for visitors in regions that require it.

Cookies

WattCosts uses cookies through Google Analytics to collect anonymous usage data. These are first-party and third-party cookies set by the Google Analytics service. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

We do not use cookies for advertising, retargeting, or tracking across other websites at this time.

Your Rights

GDPR (European visitors): You have the right to access, correct, or delete any personal data we hold about you. Since we collect only anonymous analytics data, there is typically no personally identifiable data to access or delete. If you have concerns, contact us using the information below.

CCPA (California residents): You have the right to know what personal information is collected and to opt out of the sale of personal information. WattCosts does not sell personal information.

Children's Privacy

WattCosts is not directed at children under 13, and we do not knowingly collect personal information from children.

We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
