Real Online Ruler ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our online ruler tool at realonlineruler.com (the "Service").
We believe in minimal data collection. Our online ruler tool is designed to work entirely in your browser without requiring accounts, logins, or personal information.
We do not collect any personal information. Real Online Ruler is a fully client-side application. All ruler calculations, calibration data, and preferences are stored locally in your browser using localStorage. No data is sent to our servers.
The only data we may collect is standard anonymous usage analytics (page views, browser type, device type) via our hosting provider to help us improve the service. This data cannot be used to identify you personally.
We use browser localStorage to save your calibration settings and theme preference (dark/light mode). This data stays on your device and is never transmitted to us. You can clear this data at any time through your browser settings.
We use Google Fonts for typography and our hosting provider for content delivery. These services may collect standard server logs including IP addresses and browser information. We do not use tracking cookies, analytics scripts, or advertising networks.
Since we do not collect or store your data on our servers, there is no risk of data breach affecting your personal information. All processing happens locally in your browser.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
If you have questions about this Privacy Policy, please contact us.
