Privacy Policy
Last updated: April 27, 2026
🔒 TL;DR: All calculator computations run 100% in your browser. We never see, store, or transmit your calculation inputs (weight, income, etc.). The only data we receive is what you explicitly submit via the Contact form or PayPal payments.
1. Information We Collect
Information you provide voluntarily:
- Contact form: Name, email address, and message content — submitted via Web3Forms.
- PayPal payments: When you purchase a Health Plan PDF ($1), PayPal processes the transaction. We receive your PayPal name and transaction ID. We do not see your card details.
Information collected automatically:
- Analytics: We may use privacy-focused analytics to count page views and understand which calculators are most popular. No personally identifiable information is tracked.
- Local storage: We store your recently-used calculators and theme preference in your browser's localStorage. This data never leaves your device.
2. How We Use Your Information
- To respond to your Contact form messages.
- To fulfil Health Plan PDF downloads after PayPal payment.
- To improve the site based on aggregate, anonymous usage patterns.
We do not sell, rent, or share your personal information with third parties for marketing purposes.
3. Data Processing & Security
All calculator inputs are processed client-side. Your health data (weight, height, age, gender, etc.) is never transmitted to our servers. Calculations happen entirely in your browser using JavaScript.
Contact form submissions are transmitted securely (HTTPS) to Web3Forms. PayPal transactions are processed through PayPal's PCI-compliant infrastructure.
4. Cookies & Third-Party Services
We use the following third-party services that may set cookies:
- Google AdSense: May set advertising cookies when ads are active. You can manage ad personalisation at Google Ad Settings.
- Google Fonts: We load the Inter font from Google Fonts. Google's privacy policy applies.
- PayPal: PayPal's SDK may set cookies during the payment process. See PayPal's Privacy Policy.
- Web3Forms: Processes contact form submissions. See Web3Forms Privacy Policy.
5. Your Rights (GDPR / CCPA)
If you are located in the EU/EEA or California, you have the right to:
- Access: Request a copy of any personal data we hold about you.
- Deletion: Request deletion of your personal data.
- Correction: Request correction of inaccurate data.
- Opt-out: Opt out of any future communications.
Since we store minimal data (only contact form submissions), exercising these rights is straightforward. Contact us at the address below.
