The safe setup guide
- Tag what's sensitive. Anything between
<private>and</private>isn't stored: passwords, tokens, client data. - Even better: don't paste passwords into the chat. What never goes in doesn't need hiding.
- You can skip the sign-in. If it offers an account or Cloud Sync, memory still works on your own Claude plan.
- Know where it lives. Settings and memory sit in the
~/.claude-memfolder on your computer.
