Privacy Policy

1. Who We Are

Water Intake Calculator ("we", "us", "our") operates waterintakecalculator.org, a free tool for estimating personal daily water intake. This policy explains what information the site collects, why, and what choices you have.

2. Information We Collect

Calculator inputs. The figures you enter into a calculator (weight, age, activity level, and similar) are processed in your browser to produce a result. We do not require an account and do not store these inputs against your identity on our servers.

Automatically collected data. Like most websites, our server and any analytics or advertising tools we use may automatically log standard technical information such as IP address, browser type, device type, referring page, and pages visited, typically via cookies or similar technologies.

Information you provide directly. If you contact us by email or a contact form, we collect whatever information you choose to include in that message so we can respond to you.

3. Cookies

We may use cookies and similar technologies for essential site functionality, to remember your preferences (such as your selected unit system or language), and — if enabled — for aggregated, anonymised analytics to understand how the site is used. You can control or disable cookies through your browser settings; doing so may affect some site functionality.

4. Advertising and Analytics

If this site displays third-party advertising or uses third-party analytics services, those providers may set their own cookies and collect data according to their own privacy policies, over which we have limited control. Where such services are used, they are typically operated by well-known providers (for example, Google Analytics or standard ad networks) whose own privacy documentation governs their specific data practices.

5. How We Use Information

• To operate, maintain, and improve the calculators and site content
• To understand aggregated usage patterns (which calculators are popular, which languages are used)
• To respond to enquiries sent through our contact channels
• To detect and prevent technical issues, abuse, or security incidents

We do not sell personal information to third parties.

6. Your Rights (EU/UK/EEA Visitors — GDPR)

If you are located in the European Union, European Economic Area, or United Kingdom, you have rights under the General Data Protection Regulation (GDPR) and UK GDPR, including the right to access, correct, or delete personal data we hold about you, the right to object to or restrict certain processing, and the right to data portability. Since this site does not require accounts and does not store calculator inputs against your identity, most requests will relate to cookie/analytics data or direct correspondence; contact us using the details below to exercise these rights.

7. Your Rights (California Residents — CCPA/CPRA)

California residents have the right to know what personal information is collected, to request deletion of personal information, and to opt out of the sale or sharing of personal information. We do not sell personal information as defined under the CCPA/CPRA.

8. Data Retention

We retain automatically collected technical/analytics data only as long as reasonably necessary for the purposes described above, and retain direct correspondence (such as contact form submissions) only as long as needed to address your enquiry and for our own record-keeping purposes.

9. Children's Privacy

This site is not directed at children under 13 (or the relevant minimum age in your jurisdiction), and we do not knowingly collect personal information from children. Our Child Water Intake Calculator is intended for use by parents and caregivers on behalf of a child, not by children themselves.

10. Changes to This Policy

We may update this policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. The "Last updated" date at the top of this page reflects the most recent revision.
