-# Privacy
+# Privacy
+By default, all information you save in PluralKit will be **public**. 
+Using the lookup commands, anyone can look at your system and the information within.
+This is often useful! The original intention of the bot was to function as a "profile", similar to someone's public Twitter or Tumblr account.
+
+However, this may not be what everyone wants. 
+As such, PluralKit offers options to make information **private** to others.
+Every privacy option can be set to either **public** or **private**. Public data can be seen by anyone (including through [the API](../api.md)), wheras private data can only be seen by you.
+
+::: warning
+The privacy options only apply to lookups **by** others. 
+When you look up information about your own system, **even in public servers**, all information will be shown.
+So, be careful not to pull up private information in public :slightly_smiling_face:
+:::
+
+## System privacy
+Systems currently have four privacy settings:
+
+- **Description** privacy
+- **Member list** privacy *(affects [member listing](./listing.md))*
+- **Current front** privacy
+- **Front/switch history** privacy
+
+::: tip
+It's possible to have a **private current front** and a **public front history**.
+However, you can then see your current fronter through your front history.
+This doesn't make much sense. :sweat_smile:
+:::
+
+You can view your system's current privacy settings using the following command:
+<Cmd>system privacy</Cmd>
+
+You can **change** your system's privacy settings using the following command:
+<Cmd>system privacy <Arg>subject</Arg> <Arg>level</Arg></Cmd>
+
+The argument <Arg>subject</Arg> should be either:
+- <Arg>description</Arg>
+- <Arg>list</Arg>
+- <Arg>front</Arg>
+- <Arg>fronthistory</Arg>
+- <Arg>all</Arg> (changes <strong>every setting</strong> at once)
+ 
+The argument <Arg>level</Arg> should be either <Arg>public</Arg> or <Arg>private</Arg>.
+
+**For example:**
+<CmdGroup>
+<Cmd comment="Make your member list private">system privacy <Arg>list</Arg> <Arg>private</Arg></Cmd>
+<Cmd comment="Make everything public">system privacy <Arg>all</Arg> <Arg>public</Arg></Cmd>
+</CmdGroup>
+
+## Member privacy
+Members currently have six privacy settings:
+
+- **Name** privacy
+- **Description** privacy
+- **Birthday** privacy
+- **Pronoun** privacy
+- **Metadata** privacy *(affects message count, last message, last switch, etc)*
+- **Visibility** *(affects whether this member is shown in your system's [member lists](./listing.md))*
+
+::: warning
+There are a couple gotchas with these settings:
+- Since PluralKit still needs to refer to a member, **name privacy only applies when a display name is set**. Any time PluralKit needs to show the member name, it'll *instead* show the display name.
+- All members can always be looked up by [5-character ID](./ids.md), **even when visibility is private**. However, these IDs are impractical to guess, so as long as you don't share it, it'll still be private.
+:::
+
+You can view your member's current privacy settings using the following command:
+<Cmd>member <Arg>member</Arg> privacy</Cmd>
+
+You can **change** your system's privacy settings using the following command:
+<Cmd>member <Arg>member</Arg> privacy <Arg>subject</Arg> <Arg>level</Arg></Cmd>
+
+The argument <Arg>subject</Arg> should be either:
+- <Arg>name</Arg>
+- <Arg>description</Arg>
+- <Arg>birthday</Arg>
+- <Arg>pronouns</Arg>
+- <Arg>metadata</Arg>
+- <Arg>visibility</Arg>
+- <Arg>all</Arg> (changes <strong>every setting</strong> at once)
+ 
+The argument <Arg>level</Arg> should be either <Arg>public</Arg> or <Arg>private</Arg>.
+
+**For example:**
+<CmdGroup>
+<Cmd comment="Make Craig's description private">member <Arg>Craig</Arg> privacy <Arg>description</Arg> <Arg>private</Arg></Cmd>
+<Cmd comment="Hide Jane from member lists">member <Arg>Jane</Arg> privacy <Arg>visibility</Arg> <Arg>private</Arg></Cmd>
+</CmdGroup>
