Data handling notice
Browser-local processing: the main calculation or conversion runs in your browser.
No server storage: except for UI preferences such as favorites, ZHS does not store your input files or text on the server.
Sensitive-data caution: even with local processing, avoid entering production secrets, national IDs, financial data, or raw customer data into public web tools.
