SnapWaterCalc respects your privacy and is committed to protecting your personal data. This policy explains how information is handled when you visit our website and use our hydration calculator.
All calculator inputs — body weight, biological sex, activity level and climate — are processed entirely in your browser. They are never transmitted to, collected by, or stored on our servers.
We use Google Analytics 4 with Consent Mode v2. Analytics and advertising storage are denied by default until you give consent. You can withdraw consent at any time from the Cookie Policy page.
Under GDPR and CCPA you have the right to access, correct, delete and restrict processing of personal data, and to object to processing. Because we store no personal health data, most requests concern analytics cookies only.
