Privacy Policy

Last updated: March 2026

Data We Don't Collect

All BAC calculations happen entirely in your browser. We never collect, store, or transmit:

• Your BAC results
• The drinks you enter
• Your weight or gender

Your profile preferences (weight, gender, unit) are saved only in your browser's localStorage and never leave your device.

Analytics

If you accept cookies, we use Google Analytics 4 and Microsoft Clarity to understand how our site is used. These tools collect anonymous usage data (pages visited, time on site, device type). No personal health data is collected.

You can decline analytics cookies when prompted. Your choice is stored locally and respected on future visits.

Cookies

We use only essential localStorage for functionality (your profile, cookie preference). Analytics cookies are loaded only after your explicit consent.
