Permissions it asks for

Mjerg requests what it needs to run every category. If you're only after part of it, you can safely withhold the rest. The commands that need a missing permission will say so instead of failing silently.

Read & send messagesRequired. Without it, nothing works at all
Manage messagesPurge, pin, snipe, sticky messages, automod deletions
Manage rolesAuto-roles, reaction roles, level roles, !role
Ban & kick membersModeration commands only. Drop it if you don't want the bot able to ban
Manage nicknames!nick only
Add reactionsPolls, reaction roles, starboard
View audit log!auditlog only

Mjerg's own role has to sit above anyone it's expected to moderate. This is an Osmium rule, not a Mjerg one, and it's the cause of most "the bot won't ban them" reports.

What it stores

Mjerg has to see message content to spot commands, count XP, run the counting game and apply automod. Seeing is not keeping. This is what actually gets written down:

Community & channel IDsSo settings can be looked up. Kept while Mjerg is in the community
Your settingsPrefix, channels, automod rules, triggers, tags, sticky messages
Moderation recordsWarnings and their reasons, with who issued them and when
Levelling & economyXP totals and coin balances per member, per community
Things people asked it to keepQuotes, tags, reminders, birthdays, AFK notes
Snipe cacheThe most recent deleted and edited message per channel, in memory only. Gone on restart
Ordinary message textNot stored
Voice audioNever accessed. !voice reads channel membership, not sound
Sold or shared with anyoneNo. Not for ads, not for training, not for anything

Remove Mjerg and its stored data for your community is deleted. If you want that done sooner, or want a copy of what's held first, email works.

Not planned

Worth saying out loud so nobody waits on it:
