Privacy Policy

Last Updated: June 2026

Your privacy matters to us. We built ETG Calculator with a "privacy-first" approach because we understand that users searching for ETG detection information often have legitimate privacy concerns.

The Short Version

• Your calculations stay on your device. All calculations happen in your browser—nothing is sent to our servers.
• We don't store your inputs. Your drinking amount, timing, and other inputs are never saved anywhere.
• No account required. You don't need to sign up or provide personal information.
• Third-party analytics. We use Google Analytics to understand site usage. This service may use cookies.
• Advertising. We show ads through Google AdSense, which may use cookies to personalize ads. You can opt out (see the Advertising section below).

How Our Calculator Works (Privacy-Wise)

When you use ETG Calculator:

1. You enter your information (drinks, timing, etc.)
2. All math happens right in your browser
3. Results display on your screen
4. When you close the page, your data is gone

Your calculation inputs (drinks, timing, weight) are processed entirely in your browser and are not transmitted to our servers. We have no way to access or store this data.
