- When rankings are reset, the data of the column used for rankings can be reset to 0.(You can set this in the console.)
- Columns specified as additional fields cannot be reset.
If the column data is set to reset to 0 when rankings are reset, DB usage may occur for the number of users who have participated in the rankings.

Ranking is reset every day/every Monday/1st of every month at the time of reset.

One-time ranking
In the case of one-time ranking, the ranking resets at the same time when the ranking operation period ends.
- As soon as the ranking is reset, the ranking rewards are sent out to users via mail.
- Ranking information is stored on the server and is retained for one day after the reset. The data is deleted after one day has passed from the time of reset.
Remove users from rankings
You can remove users/guilds from the rankings via the BACKND Console > Ranking menu.
