Privacy Policy
Last updated: April 2026
Who we are
This website is operated by yknot s. r. o., Ovocna 20, 92101 Piestany, Slovak Republic ("we", "us", "our"). We are the data controller for your personal data processed through this website.
For questions about this policy or your data, contact us at info@monoceros.tools.
What data we collect
Website analytics
We use Google Analytics 4 (measurement ID G-KDLFPELGCL) and Facebook Pixel to understand how visitors use our website. These services collect:
- Pages visited and time spent on pages
- Referring website or search terms
- Browser type, screen resolution, and operating system
- Approximate geographic location (country/city level, not precise)
- Device type (desktop, mobile, tablet)
This data is collected using cookies and similar technologies. You can opt out by declining cookies when prompted, or by using your browser's cookie settings.
Grasshopper plugin analytics
The Monoceros 3 Grasshopper plugin collects anonymous usage data to help us understand how the software is used and to guide product improvements. The following data is collected:
- Session frequency and duration
- EULA acceptance
- Component usage and error rates
- Solver performance metrics (module, rule, and slot counts; solve duration; result type)
- License tier, Rhino version, operating system, and plugin version
- Country of use, derived from your IP address - the IP address itself is never stored
All data is associated with a random anonymous identifier (UUID) that cannot be linked to your identity. This analytics identifier is separate from the device identifier used for license validation, ensuring that analytics data cannot be linked to your license email. No project data, geometry, file names, or personal information is collected. Legal basis: legitimate interest (GDPR Article 6(1)(f)).
To determine country of use, your IP address is sent to ip-api.com for geolocation lookup. Only the resulting country code is stored; the IP address is never persisted by us.
You can opt out of plugin analytics at any time by creating an empty file at
%LOCALAPPDATA%\monoceros\analytics_optout (Windows) or
~/.local/share/monoceros/analytics_optout (macOS), or by setting the
environment variable MONOCEROS_NO_ANALYTICS=1.
You may request access to or deletion of analytics data associated with your anonymous identifier by contacting info@monoceros.tools.
