Century Ledger is a small, private program kept by the owner of Restored Century, a YouTube channel of restored archive films. It runs on the owner's own computer and has one job: to fetch the channel's own YouTube Analytics reports, so the owner can keep its figures in one place next to their production notes.

The figures it reads

Daily totals for the channel and for each of its videos: views, watch time, average view duration and percentage, subscribers gained and lost, thumbnail impressions and click-through rate, and the channel's estimated revenue.

What it cannot do

Century Ledger only reads. It cannot upload, edit or delete a video, write or remove a comment, or change a playlist or any channel setting. It works with the Restored Century channel alone.

Who uses it

Only the channel's owner. The program is not offered to anyone else, and there is nothing to sign up for.
