Data Collection

Nexa Labs does not collect personal data through the calculator tools. All calculations are performed entirely in your browser. Inputs are stored only in your browser's local storage for convenience and are never transmitted to our servers.

Email Capture

If you voluntarily submit your email address through our early access form, that email is processed by Web3Forms and delivered to our team. We will only use it to contact you about Nexa Labs product updates. We will never sell or share your email with third parties.

Analytics

We use Google Analytics 4 and Google Tag Manager to understand aggregate usage patterns (e.g., which calculators are used most). This data is anonymous and does not identify individual users. You can opt out via your browser's privacy settings or a privacy-focused browser extension.

Cookies

We use browser local storage to remember your syringe type preference (U-100 or U-40). Google Analytics may set cookies for analytics purposes.

Disclaimer

Nexa Labs is intended for research purposes only. Nothing on this site constitutes medical advice.
