This Privacy Policy explains how WaterIntakeCalculator ("we", "us", "our") collects, uses, and protects information when you visit waterintakecalculators.com (the "Site"). By using the Site you agree to the practices described below.
1. Information We Collect
We keep data collection to a minimum. We may collect:
- Calculator inputs — weight, age, activity, climate, etc. These are processed in your browser to produce a result and are not tied to your identity.
- Usage analytics — anonymized page views, device type, country, and referrer via privacy-respecting analytics (e.g., Google Analytics 4 with IP anonymization).
- Newsletter data — if you subscribe, we store your email address to send hydration tips. You can unsubscribe at any time.
- Account data — only for admin users, we store email and role via our authentication provider.
2. Cookies
We use essential cookies to run the Site and optional cookies for analytics and advertising. You can control cookies through your browser settings. Blocking non-essential cookies does not affect calculator functionality.
3. Advertising
We may display advertisements from third-party networks such as Google AdSense. These providers may use cookies to serve ads based on your visits to this and other sites. You can opt out of personalized advertising via Google Ad Settings.
4. How We Use Information
- To operate calculators and generate results
- To improve content quality and site performance
- To send newsletters (only if you subscribed)
- To detect abuse and secure the Site
5. Data Sharing
We do not sell your personal information. We share data only with trusted service providers (hosting, analytics, email delivery) under contract, or when required by law.
6. Your Rights
Depending on your region (GDPR, CCPA, etc.), you may have the right to access, correct, delete, or export your data, and to withdraw consent. Contact us at privacy@waterintakecalculators.com to exercise these rights.
7. Children
The Site is not directed at children under 13. We do not knowingly collect personal information from children. Kids' calculators are intended for parents and caregivers.
8. Data Security
We use HTTPS, encrypted databases, and role-based access controls to protect data. No system is 100% secure, but we work continually to safeguard information.
9. Changes to This Policy
We may update this policy from time to time. Material changes will be announced on this page with a new "Last updated" date.
