Privacy Policy
Last updated: 6/18/2026
Introduction
Health Calculators Hub ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our calculators.
Information We Collect
Calculator Inputs
When you use our calculators, your inputs (weight, height, age, etc.) are stored locally in your browser's localStorage. This data never leaves your device and is not transmitted to our servers.
Contact Form
When you submit our contact form, your message is sent via EmailJS directly to our email address. We do not store form submissions in a database. EmailJS processes the transmission but does not retain your data.
Analytics
We use Google Analytics to understand how visitors use our site. This includes anonymous information such as page views, device type, and geographic location (country/city level only).
Advertising
We display ads through Google AdSense. AdSense may use cookies and similar technologies to serve relevant ads based on your browsing activity across sites. You can control ad personalization through Google's Ad Settings.
How We Use Information
- To provide calculator functionality and save your preferences locally
- To analyze site usage and improve our services
- To display relevant advertisements
Data Storage
All calculator inputs are stored exclusively in your browser's localStorage. We do not have access to this data. You can clear this data at any time through your browser settings.
Data Retention
We retain calculator input data only as long as it remains in your browser's localStorage. Since this data is stored locally and not transmitted to our servers, there is no formal retention period. You maintain full control to delete this information at any time through your browser settings. For contact form submissions, messages are delivered directly to our email address and are not stored on our systems. Analytics data collected via Google Analytics is retained according to Google's policies (typically 14 months unless manually deleted).
Security Measures
We implement industry-standard security measures to protect data in transit. When using third-party services like Google Analytics or AdSense, data transmission is encrypted via HTTPS. Our calculators are designed to minimize data exposure by storing inputs locally rather than on remote servers. While we cannot control third-party security practices, we ensure all external services comply with EU-US Privacy Shield Frameworks where applicable. Users should always use up-to-date browsers and enable built-in security features for optimal protection.
Third-Party Services
We use the following third-party services:
- Google Analytics: Website analytics
- Google AdSense: Advertisement serving
- EmailJS: Contact form email delivery (does not store your messages)
Your Rights
You have the right to:
- Clear your locally stored calculator data at any time
- Opt out of analytics tracking using browser plugins
- Control ad personalization through Google Ad Settings
Changes to This Policy
We may update this Privacy Policy to reflect service improvements or legal requirements. The 'Last updated' date at the top of this page will always show the most recent revision. Significant changes may be communicated via email to users who have submitted contact forms, or through prominent notices on our homepage. Continued use of our calculators after policy updates constitutes acceptance of the revised terms. We recommend reviewing this policy periodically to stay informed about our data practices.
