Summary

WaterIntakeCalc.com does not collect, store, or transmit any personal data. All hydration calculations run entirely in your browser (client-side). We use Google Analytics for anonymous usage statistics and Google AdSense for advertising. We do not sell data because we don't have any.

Weight, age, gender, or health information entered in calculators
IP addresses (beyond standard server logs for security)

Browsing history or behavior tracking

When you use our calculators, the following data is processed entirely in your browser and never leaves your device:

Local Storage

We use localStorage for:

Language preference — Stores whether you have been redirected to a localized version of the site based on your country. Stored as "wic_lang_redirected" key.
No calculator inputs or results are stored

You can clear this at any time via your browser settings.

Third-Party Services

We use the following third-party services:

Google Analytics (GA4) — Collects anonymous usage statistics such as page views, session duration, and referral source. Google Analytics uses cookies to distinguish unique users. No personal data is collected. You can opt out via the Google Analytics Opt-Out Browser Add-on.
Google AdSense — Serves advertisements. AdSense uses cookies for ad personalization and measurement. You can manage ad personalization via Google Ad Settings.
Cloudflare Pages — Our hosting provider. May log standard access information for security purposes (see Server Logs section below).

Calculator inputs and results are never sent to any third party. All calculations remain in your browser.

If you use our contact form, the data you provide (name, email, message) is sent to our email service provider (Formspree or similar). We only use this to respond to your inquiry. We do not add you to mailing lists or use your data for marketing.

Server Logs

Our hosting provider (Cloudflare Pages) may log standard access information for security and operational purposes:

These logs are managed by Cloudflare and subject to their privacy policy. We do not analyze them for marketing or tracking.

You can clear localStorage (theme preference) anytime in browser settings
You can request deletion of any contact form submissions by emailing us
You can opt out of future AdSense personalization via Google's ad settings
