Privacy Policy
Last Updated: August 6, 2026
1. Zero Photo Cloud Storage (Local Processing)
At CalcHeight.com, your privacy is paramount. When you upload a photograph to our Interactive Photo Scale Calibrator, the image file is processed entirely in your web browser's memory (HTML5 Canvas API).
We do NOT upload, transfer, store, or view your uploaded photos on any external server or database. Once you close your browser tab or reset the tool, all temporary image data is immediately purged.
2. Information We Collect
Because we do not require user accounts or registration, we collect minimal non-personally identifiable information strictly necessary to operate and improve our website:
- Analytics & Diagnostics: Standard web server log files (IP addresses, browser type, referring pages, access times) for security and traffic monitoring.
- Local Storage: We use browser `localStorage` to save your UI unit preference (imperial vs. metric).
3. Cookies & Tracking Technologies
CalcHeight.com uses essential session cookies and standard web analytics tools to measure aggregate website traffic patterns. You may disable cookies in your browser settings without affecting the functionality of our height calculator.
4. Third-Party Links & Services
Our website may contain links to third-party scientific resources or documentation. We are not responsible for the privacy practices of external websites. We encourage you to read their privacy policies upon visiting.
5. Children's Privacy Notice
CalcHeight.com is designed for educational use by individuals of all ages. Because no personal identification data or photographs are collected or transmitted, our site complies with COPPA and GDPR regulations regarding minors.
