Privacy Policy
Last updated: January 2025
Your Privacy is Protected
My BMI Score is built with privacy at its core. All calculations happen in your browser. We do not collect, store, transmit, or sell any personal data. Period.
Data Collection
We collect absolutely no personal data. When you use our BMI calculator:
- All calculations are performed locally in your browser using JavaScript
- Your weight, height, age, and other inputs never leave your device
- We do not use cookies to track you
- We do not use analytics or tracking scripts
- We do not collect IP addresses or device information
- We do not require registration or accounts
Local Storage
Our calculator uses your browser's LocalStorage feature to save your BMI history and preferences (such as language and theme settings). This data:
- Is stored only on your device
- Never leaves your browser
- Is not accessible to us or any third parties
- Can be deleted at any time by clearing your browser data
Third-Party Services
We use minimal third-party services to deliver our website:
- Google Fonts: We load the Inter and JetBrains Mono fonts from Google Fonts for better typography
- Hosting Provider: Our website is hosted on servers that may log standard web server information (IP addresses, timestamps) for security purposes
We have no control over these third-party privacy policies. We recommend reviewing their privacy policies if you have concerns.
No Advertising or Marketing
We do not:
- Display advertisements
- Sell or share your data with advertisers
- Send marketing emails (we don't even collect email addresses)
- Use retargeting or remarketing pixels
- Participate in affiliate marketing programs
Children's Privacy
Our service includes a Children & Teens BMI calculator. However, we do not knowingly collect any personal information from children. All calculations happen locally in the browser, and no data is transmitted to our servers.
Parents and guardians should supervise children's use of the calculator and consult with healthcare professionals for medical advice.
Data Security
Since we don't collect or store any personal data on our servers, there is no centralized database that could be hacked or breached. Your data stays on your device, under your control.
We use HTTPS encryption to secure the connection between your browser and our servers, protecting against man-in-the-middle attacks.
Your Rights
Under GDPR, CCPA, and other privacy regulations, you have rights regarding your personal data. Since we don't collect or store any personal data, most of these rights are automatically satisfied:
- Right to Access: All your data is on your device, accessible to you at any time
- Right to Deletion: Clear your browser's LocalStorage to delete all saved data
- Right to Portability: Your data never leaves your device
- Right to Object: Not applicable since we don't process your data
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. Any changes will be posted on this page with an updated "Last updated" date at the top.
Since we don't collect email addresses, we cannot notify you of changes. We encourage you to review this policy periodically.

Summary
In plain English: We built this tool to be completely private. Everything happens in your browser. We can't see your data because we never receive it. No tracking, no cookies, no analytics. Your health information stays on your device, where it belongs.
