We analyze climbing videos and images uploaded by users to provide movement feedback, route records, and analysis results. Cloud storage and synchronization are provided to users who purchase a subscription plan, and analysis data for general users is processed only on-device and is not collected on our servers.

CruxCut uses on-device machine learning models to provide climber tracking and video analysis features.

All AI processing is performed locally on the user's device. CruxCut does not send user videos, photos, notes, or other personal content to any third-party AI service for processing.

Website attribution statistics

The website records bounded campaign or referring-site categories and App Store, Google Play, and Discord link click counts in Cloudflare Workers Analytics Engine. These analytics do not store full URLs, search terms, IP addresses, user agents, or personal identifiers. Attribution is kept in the current tab’s sessionStorage for up to 30 minutes, and these statistics use no tracking cookies or visitor IDs. Collection stops when Global Privacy Control or Do Not Track is enabled. These are event counts, not verified installs or Discord joins.

Homepage improvement experiments

To compare homepage designs, visitors are split into two groups and only the group letter (a or b) is stored in the browser’s localStorage. This value does not identify anyone and is removed when you clear site storage.

Website behavior analytics

To understand and improve how the website is used, we use the tools below. Neither tool is loaded when Global Privacy Control or Do Not Track is enabled.

International transfer: this information is sent to each provider’s servers in the United States when you visit the website and is kept until the improvement purpose is met or for the period set by each provider’s retention policy. You can opt out by clearing cookies and site storage or by enabling Global Privacy Control. Contact: support@cruxcut.com
