Your privacy is important to us
Last updated: 10/26/2025
Privacy-First Approach
Welcome to HydrationMap. Your privacy is important to us. This Privacy Policy explains how we treat information in connection with your use of our website and services.
1. No Personal Information Collected
- HydrationMap does not collect or store any personally identifiable information (PII) from users (e.g. name, email, phone, address).
- There is no user registration or login functionality.
- All data input by you into the calculator (age, weight, etc.) is processed locally in your browser and is not sent to any server.
- HydrationMap’s core app and calculator do not set cookies or run analytics scripts. However, advertising delivered via Ezoic and its partners may use cookies and similar technologies. See the Ezoic section below.
- We do not sell, rent, or share any user-provided calculator data with third parties.
2. Local Processing Only
- All computations, formulas, and data handling occur in client-side JavaScript running in your browser or device.
- No server-side storage or logging of user inputs or results is performed.
3. Anonymity and Ephemeral Data
- Because there is no transfer or storage of user input data, your usage remains anonymous.
- Once you close your browser tab or navigate away, any state or data in the calculator is lost (unless you intentionally save/export it).
4. Third-Party Services & Links
- If the site links to external resources (e.g. social media, external guides), clicking those links may involve third-party domains. We encourage you to review their privacy practices.
- We do not embed third-party analytics or tracking scripts within the app core. We do display ads via Ezoic, which may load its own scripts and cookies. See the Ezoic policy below.
5. Minors
Since we do not collect any personal data, HydrationMap can be used by users of any age without submitting personal info.
6. Changes to this Policy
- We may update this Privacy Policy occasionally (for clarity, legal compliance, or site changes).
- The “Last updated” date above will reflect when changes occur.
- We encourage you to check back periodically.
