HydroCalc ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how information is collected and used when you visit our website and use our tools.
1. No Personal Data Collection
Our Water Intake Calculator runs entirely within your browser. We do not:
- Collect, store, or transmit any personal data you enter into the calculator (weight, age, gender, etc.).
- Maintain user accounts or require login.
- Use cookies for tracking or advertising purposes.
- Operate a database that stores your inputs or results.
All calculations happen locally in your browser using JavaScript. Your data never leaves your device.
2. Google Fonts
We use Google Fonts to display the Figtree and Noto Sans typefaces. When your browser loads our pages, it makes a request to Google's font CDN (fonts.googleapis.com). This means Google may receive your IP address as part of this technical request. We do not control this process. You can review Google's Privacy Policy for more information.
3. Analytics
If we add analytics in the future (e.g., Google Analytics), we will update this policy accordingly and ensure compliance with applicable privacy laws. At this time, no third-party analytics scripts are loaded on this site.
4. Third-Party Links
Our pages may contain links to external websites (e.g., the National Academies of Sciences, WHO). We are not responsible for the privacy practices or content of those sites. We encourage you to review the privacy policies of any external sites you visit.
5. Children's Privacy
Our tools are intended for general wellness guidance. We do not knowingly collect any information from children under the age of 13. The calculator supports inputs for ages 5+ for informational purposes only, with parental oversight recommended.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected with a revised "Last updated" date at the top of this page.
