1. The "Zero-Storage" Calculator
We believe your health data belongs to you. Drinkmeter is designed as a client-side application.
- No Database Storage: When you enter your weight, gender, or drink choices, this data is processed exclusively within your web browser using temporary memory that is deleted when you close the tab.
- No Transmission: Your specific calculator inputs are never sent to, stored on, or analyzed by our servers.
- Volatile Data: Because we do not use Cookies to save your session, all data is permanently erased the moment you refresh the page or close the tab.
2. Anonymous Usage Analytics
While we do not track what you calculate, we do track how the website performs to identify bugs and improve user experience. We use the following third-party services:
- Google Analytics 4 (GA4): Collects anonymous data such as page views, device type, and general geographic location (country/city level). We have enabled IP Anonymization.
- Vercel Analytics: Helps us monitor site speed and performance vitals (Core Web Vitals).
You can opt-out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.
3. No Ads or Affiliate Links
Drinkmeter is an independent educational tool. To maintain objectivity and trust:
- We do not display third-party advertisements.
- We do not use affiliate links or earn commissions from alcohol manufacturers.
- We do not sell user data to third parties.
4. Your Rights (GDPR & CCPA)
Under global privacy laws (including GDPR and CCPA), you have rights regarding your personal data. However, because Drinkmeter does not collect Personal Identifiable Information (PII) such as names, emails, or specific health records, we hold no data to "export" or "delete" upon request.
If you contact us via email, we will use your email address solely to reply to your inquiry.
