Statistics

Lychee SE bundles two distinct subsystems here: usage statistics about your library’s storage and growth, and engagement metrics tracking how photos and albums are viewed, downloaded, and shared.

Accessible from the dedicated Statistics page:

• Storage breakdown — total space used, broken down per size-variant type (thumbnail, small, medium, original, etc.) and per user.
• Activity over time — a calendar-style chart of photo counts, by upload date or by the photo’s original taken-at date.
• Per-album breakdown — a table of storage usage and photo counts per album, both for the album’s own photos and including all descendants, collapsible into per-user totals.
• Regular users only see statistics for their own photos and albums; admins see the whole instance.

Enable metrics_enabled to start recording view, download, and share counts on photos and albums:

• Counts appear as small badges on albums and photos, and on Flow cards.
• Anonymous visitors are always counted when enabled; logged-in users are only counted if metrics_logged_in_users_enabed is also on. Admin activity is never counted, so browsing as an admin won’t inflate your own stats.
• Who can see these counts is controlled separately by metrics_access (admin, owner, logged-in users, or public).

live_metrics_enabled additionally turns on a real-time activity feed — a running log of visits, favourites, downloads, and shares as they happen. Photo-level page visits are deliberately excluded from this feed to keep it readable; only album-level visits and the other actions are listed. As with the counts above, non-admins only ever see activity for their own albums and photos. Entries older than live_metrics_max_time days are purged automatically the next time the feed is loaded — there’s no separate scheduled cleanup job. Access to the feed itself is controlled by live_metrics_access (admin or logged-in users).

The Pro settings category controls engagement metrics:
