What this site stores

Storage

This site stores no analytics, no cookies, no third-party tracking. The data behind every chart is downloadable from /data — no JavaScript needs to run for you to read what we know.

Browser storage (localStorage)

A few visitor-experience features write to your browser's localStorage. Nothing is sent to any server. All keys clear with a browser data reset.

• ytpool_last_visit — snapshot of channel stats from your previous visit, used to compute the “since you last visited” delta line on the next visit.
• ytpool_compare_selection — your in-progress video comparison picks (up to 3 video IDs), preserved across page refreshes and back-navigation.
• ytpool_local_data_dismissed — records that the owner-mode “your data stays on this machine” banner has been dismissed for this browser.
• ytpool_value_hook_seen — marks the first-visit value-proposition prompt as seen, so it hides on return visits.

Cloudflare Web Analytics
