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

A covered pick. Anyone can use it as a private drop-in, with no setup or know-how. Enough for most people. Threat levels
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.

Logseq license, in plain English
AGPL-3.0 Strong copyleft · network
Free to use, even commercially. Changes must be published under the same license, and running a modified version as a network service counts as distributing it.

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.
