Privacy Policy
Last Updated: October 31, 2026 • Effective Immediately
1. Executive Summary & Zero-Tracking Model
At Number into Roman (https://numberintoroman.com), your privacy is respected by mathematical design. All mathematical conversions, date transcriptions, and arithmetic calculations take place strictly on your personal device via client-side JavaScript. None of the numbers, dates, or formulas you enter are ever transmitted, stored, or processed on remote servers.
2. Information We Do Not Collect
- We do NOT log or track any numbers or Roman numerals entered into our tools.
- We do NOT require user account registration, passwords, or personal profiles.
- We do NOT sell, lease, or monetize user browsing activities or calculations.
3. Local Storage and Client-Side Cookies
Our website may use browser localStorage solely to preserve non-identifying user interface preferences (such as light/dark mode status or recently tested Roman numbers) to enhance your browsing experience across reloads. You can clear this data at any time via your browser settings.
4. Third-Party Hosting & CDN Assets
This site is statically hosted on modern CDN networks (e.g., Vercel / GitHub Pages). Like all web servers, standard non-identifying server request logs (IP address, user-agent, timestamp) may be temporarily captured by the infrastructure provider for DDoS mitigation, rate limiting, and network stability.
5. GDPR & CCPA Rights
Under the European General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), users possess the right to be informed of data collection. Because we collect zero personally identifiable information (PII), no personal data profiles exist to access, rectify, or erase.
