how do i use the tracker?

you can’t, it’s dead.

we suggest using qbittorent.

is there an indexer or search?

no. we don’t even know what torrents are being tracked.
no torrent files can be uploaded, nor are there any hosted here.

do you keep logs?

no. there is no registration, no proxy, no database or static files.

why not support http or https?

udp is far more efficient.
