The task manager
that can’t read
your tasks.
Plan tasks, notes, and team work in a familiar workspace. Readable workspace content is encrypted before sync; account and operational metadata remain visible to the service.
Everything you need. Readable content stays client-encrypted.
Sensitive workspace content used by these features is end-to-end encrypted. Operational fields such as timing, status, relationships, counts, and event metadata remain server-visible.

Security that satisfies your auditors.
SealTask is designed so the service cannot decrypt readable workspace content. The documented architecture also identifies the metadata the service still processes.
