Privacy Policy

Last updated: November 2026. Governs data processing practices on rmstowatts.com.

1. Zero Client Data Storage

rmstowatts.com processes 100% of mathematical equations client-side inside your browser. We do not store, transmit, or log the numerical values, voltages, or speaker configurations you enter into our calculation tools.

2. Local Storage & URL States

We use browser local storage solely to remember your preferred dark/light color theme (theme key) and cookie consent status (cookie_consent key). URL query parameters (such as ?mode=6&rms=100) are evaluated exclusively in your local browser runtime for link-sharing convenience.

3. Web Analytics & Cookie Consent (Consent Mode v2)

We utilize Google Analytics 4 (GA4, Measurement ID: G-Z2P87MBQD2) to measure aggregated, anonymized website traffic, bounce rates, and device performance without collecting personally identifiable information (PII). All IP addresses are automatically truncated and anonymized.

Consent Gating: In compliance with the EU General Data Protection Regulation (GDPR) and the ePrivacy Directive, we implement Google Consent Mode v2. By default, analytics cookie storage is denied (analytics_storage: 'denied'). Tracking cookies are only activated if you affirmatively click "Accept" on our cookie consent banner. If dismissed or ignored, analytics cookies are blocked.

You can also prevent Google Analytics tracking at any time by installing the Google Analytics Opt-out Browser Add-on.

4. Third-Party Advertising & Cookies (Google AdSense)

We may display advertisements served by Google AdSense and its network partners. To ensure full compliance with Google Publisher and AdSense program policies, please note the following:

Third-Party Vendor Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to rmstowatts.com or other websites on the Internet.

Third-Party Ad Networks: Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative / AboutAds.info Consumer Choice page.

In regions governed by the European General Data Protection Regulation (GDPR) and the UK GDPR, advertising cookies are strictly gated through our Google-certified Consent Management Platform (CMP) and are not loaded without affirmative consent.
