Not encrypted, but the server will never store or analyze your private notes. Your data are plain text files.

Our take
Read the fine print first: Logseq is not encrypted, your notes are plain text files on disk, so it protects you from a snooping cloud provider, not from anyone with access to your machine. Where it shines is as a local-first outliner and knowledge base built on files you fully own, with no lock-in. Pick it if your goal is owning your data and avoiding a SaaS silo rather than defending against device-level compromise. If you need actual at-rest encryption, this is the wrong tool in this category.

Why it matters: The network clause is the point. Anyone who runs a modified version as a hosted service has to publish those changes, so the code handling your data stays inspectable. This is why privacy-first projects reach for AGPL.
