Privacy Policy
This privacy policy explains how the Ideal Water Intake website ("we", "us") collects, uses, and protects information when you use the water intake calculator. The calculator is designed to be privacy-friendly by default.
Last updated: August 15, 2026
Information we collect
The water intake calculator processes everything in your browser. The values you enter — weight, height, age, sex, activity, and climate — are used only to compute your result and are not transmitted to, or stored on, our servers. We do not require an account, and we never ask for your name or email to use the tool.
Cookies and local storage
We use local storage in your browser to remember your theme preference (light or dark mode) and to store your most recent calculator inputs so you don't have to re-enter them. This data stays on your device. Essential cookies required for the site to function may be set; we do not use advertising or tracking cookies.
Analytics and third parties
We may use privacy-respecting, aggregated analytics to understand how many people visit the site and which pages are popular. This data is anonymized and used to improve the tool. Third-party services we use (such as font or icon CDNs) may process basic request data (IP address, user agent) under their own privacy policies.
Data retention and security
Because your calculator inputs never leave your browser, we have nothing to retain or delete on our servers. Any anonymized analytics we collect are retained only as long as needed for site improvement and are protected with industry-standard measures.
Children's privacy
The calculator is designed for general audiences, including teens, but is not directed at children under 13. We do not knowingly collect personal information from children. Since no personal data is collected to use the tool, no parental consent is required to use it.
Your rights
Depending on your jurisdiction (for example, under GDPR or CCPA), you may have rights regarding your data. Because we do not collect or store personal information from the calculator, there is typically nothing to access, correct, or delete. If you believe we hold data about you, contact us and we will respond promptly.
Changes to this policy
We may update this privacy policy from time to time. Changes will be posted on this page with a revised "last updated" date. Continued use of the site after changes means you accept the updated policy.
