Privacy Policy
Effective date: April 20, 2026
1. Who We Are
ProductMetrics (productmetrics.org) is a content reference site operated by Roarke Clinton. It provides definitions, formulas, benchmarks, and examples for product metrics. The site has no user accounts, no database, and collects no personal information directly.
2. What We Collect
Analytics (with consent)
With your consent, we use UserActivity to understand how visitors interact with the site. UserActivity tracks scroll depth, click patterns, page navigation, and engagement signals. It sets a first-party cookie (__ua_vid, 1 year) for anonymous visitor identification, and stores approximate country and region (ISO codes) derived at the network edge from the request IP — the IP itself is not stored. It also receives the browser’s IANA timezone (e.g. America/Los_Angeles) reported by the browser’s Intl API. UserActivity also stores a daily-rotating one-way hash of IP + User-Agent + site ID to count same-day unique visitors; the hash changes every 24 hours and cannot be used to trace visitors across days. It respects Do Not Track browser settings. See the Cookies and local storage section below for details.
Analytics are only loaded after you accept cookies via the consent banner. If you decline, no analytics data is collected.
Feedback widget
This site includes a feedback widget operated by Communications (comms.roarke.io). The widget does not set cookies and does not collect data unless you actively submit feedback. See the widget privacy policy for full details.
Server logs
Our hosting provider (Vercel) logs IP addresses, request timestamps, URLs accessed, and HTTP headers for security and debugging. We do not access these logs for marketing purposes.
4. What We Do Not Collect
- No user accounts or personal information
- No email addresses (unless you submit feedback with one)
- No advertising or marketing tracking
- No data sold to third parties
