Skiff
Pre-acquisition E2EE suite—not for new users
Overview
Skiff was a privacy-first collaboration suite combining encrypted mail, pages, and drive-like storage with real-time co-editing.
After Notion’s acquisition, continuing as an independent service is limited—listed here as a cautionary reference for E2EE suite choices.
Do not start new de-Google projects on Skiff; existing users should plan migration.
