Privacy Policy

1. Overview & Client-Side Processing

At dBm to Watts Calculator (dbmtowatts.com), we respect and protect your privacy. All RF mathematical calculations, logarithmic conversions, impedance scaling, and unit transformations are performed entirely client-side within your web browser using local JavaScript engines. No proprietary engineering numbers, radio frequencies, transmitter powers, or system link budget parameters entered into our calculators are transmitted to or stored on our servers.

2. Local Storage & Functional Preferences

We utilize browser localStorage strictly for functional preferences:

• Visual Theme: Retaining your dark/light mode preference across browsing sessions (theme = 'dark' | 'light').
• Cookie & Ad Consent: Recording your affirmative choice regarding optional analytics and advertising cookies (dbm_cookie_consent = 'granted' | 'denied' and dbm_ad_consent = 'granted' | 'denied').

This functional preference data remains stored on your local terminal device and is never sold.

3. Analytics & Performance Telemetry

To ensure platform stability, monitor server load, and identify cross-browser rendering anomalies, we use Google Analytics 4 (GA4) (Measurement ID: G-BHFD6EEB25).

In accordance with the European Union ePrivacy Directive, GDPR, and UK PECR regulations:

• Google Consent Mode v2: All non-essential analytics and advertising storage keys are set to denied by default until you provide explicit affirmative consent.
• Anonymous Telemetry: When granted, Google Analytics collects aggregated, anonymous technical telemetry (browser type, operating system, referring domain, page performance benchmarks). IP anonymization is permanently enabled.
