Overall Safety Score

★ ★ ★ ★ ★

Verdict: Notion is a solid productivity tool with adequate security for most use cases. It is not end-to-end encrypted, meaning Notion can access your data. For most users this is an acceptable trade-off, but sensitive data should be handled carefully.

Notion is an all-in-one workspace for notes, docs, wikis, and project management used by millions of individuals and teams. It stores all data in the cloud and has SOC 2 compliance but is not end-to-end encrypted.
