The bot says No data found for this server
Tracking is off for the server, which is how every server starts. Someone with the Administrator permission runs /odin enable, and ODIN starts counting within about a minute. Time before that is not counted.
The board says No data yet for this time period
Tracking is on, but nobody has time in voice inside that window yet. Join a voice channel, or try a longer timeframe such as Last 30 Days or All Time.
/games shows nothing
Game tracking may be off. Someone with the Administrator permission runs /odin enable, which turns voice and game tracking on together, and a server that enabled ODIN before game tracking existed runs it again. /odin status shows whether game activity is enabled. A title is listed only once at least three members have played it in the window, so try Last 30 Days or All Time, and only the Playing status counts.
The boards answer as text, not as a picture
An admin may have chosen text with /odin style style:text; they bring the pictures back with /odin style style:image. ODIN also sends the text board when it cannot make a picture.
The commands do not show up
Discord lets a server limit who sees an app's commands: in Server Settings, open Integrations, choose ODIN and check its command permissions. Except /ping, the commands work only inside a server, not in direct messages.
My time is not counting
Run /odin status. If tracking is disabled, someone with the Administrator permission runs /odin enable. If tracking is on, you may have opted out of this server: run /odin optin and ODIN tracks you again from then on.
Someone wants to leave the boards
They run /odin optout themselves. They disappear from the boards, /games and the statistics, and ODIN stops tracking their voice time and games in that server. To ask for data to be removed, see the privacy page.
