Privacy Policy
Last updated: January 2025
This privacy policy explains how the Rock Mass Rating Calculator website collects, uses, and protects information when you visit and use our free geotechnical tools. We have written this policy in plain English so that it is easy to understand.
Information We Collect
The Rock Mass Rating Calculator is a client-side tool. All calculations are performed entirely within your web browser. We do not collect, store, or transmit the rock mass parameter values you enter into the calculator. Your input data never leaves your device.
We do not require you to create an account, provide your name, email address, or any other personal information to use the calculator. There are no login forms, registration walls, or mandatory data collection steps anywhere on this site.
Google Analytics 4
We use Google Analytics 4 (GA4) to collect anonymous usage statistics. This helps us understand how visitors find and use the site so that we can improve the tool over time. GA4 may collect the following types of information automatically:
- Pages visited and time spent on each page
- General geographic region (country and city level, not precise location)
- Device type, screen resolution, and browser name
- Referral source (how you arrived at the site)
- Language preference set in your browser
Google Analytics 4 operates without relying on third-party cookies in most modern browsers. Google may use first-party cookies or other identifiers to distinguish unique visitors. For full details on how Google processes analytics data, please refer to Google's Privacy Policy.
If you prefer not to be tracked by Google Analytics, you can install the Google Analytics Opt-out Browser Add-on or use a browser with built-in tracking protection.
localStorage Usage
This website uses your browser's localStorage feature to save your dark mode preference and, where applicable, your most recent calculator inputs so they persist between sessions. localStorage is a standard browser feature that stores small amounts of data on your own device. This data is never sent to our servers or any third party.
You can clear localStorage data at any time through your browser settings. Clearing this data will reset your theme preference to the default and remove any saved calculator state.
Cookies
This website does not set any first-party cookies. The only cookies that may be present are those set by Google Analytics as described above. We do not use cookies for advertising, tracking across other websites, or personalisation purposes.
Third-Party Services
Beyond Google Analytics, this website may load resources from content delivery networks (CDNs) to serve JavaScript libraries used by the calculator. These CDN requests are standard web operations and do not involve the transfer of your personal data.
We do not use any advertising networks, social media tracking pixels, or remarketing services on this site.
Data Security
The site is served over HTTPS, which encrypts all data in transit between your browser and our server. Since we do not collect or store personal data on our end, there is no personal data at risk of a breach on our servers.
Children's Privacy
This site is an educational and professional tool. We do not knowingly collect any personal information from children. Since no personal data is collected from any user, there is no specific children's data concern.
Changes to This Policy
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this page periodically.
