Can I use SealTask like a personal task manager?

Yes. SealTask works well for personal planning, private notes, checklists, due dates, recurring tasks, and search. You can start alone on Free, then upgrade to Personal or invite a team later if your workflow grows.

Can my team use SealTask like a normal task manager?

Yes. Your team still gets lists, tasks, owners, due dates, comments, checklists, notes, recurring work, audit logs, and search. The encryption runs behind the workflow instead of becoming a separate tool your team has to manage.

What can SealTask see?

SealTask servers need account, billing, routing, and sync metadata to operate the service. Workspace content such as task text, notes, comments, and private search data is encrypted on the client before sync, so it is stored as ciphertext rather than readable work.

What happens if we lose access or forget a password?

A saved backup key lets you reset your password and keep access to encrypted data. SealTask still cannot decrypt workspace content for you, so save backup keys privately and plan team access before you need recovery.
