Quick verdict.
Choose Worklist if shared team tasks contain sensitive content and privacy matters more than personal productivity shortcuts. Worklist may help with technical safeguards for regulated workflows, but PHI still requires a written compliance agreement or BAA. Choose Todoist if you want fast personal task capture, reminders, calendar views, and a generous free plan for lightweight tasks.

Security architecture.
Worklist: zero-knowledge.
Worklist encrypts all data on your device using ChaCha20-Poly1305 before it reaches our servers. We use OPAQUE PAKE for authentication so we never see your password. The encryption keys are derived from your password using Argon2id - we don't have them.
Result: Even if our database is breached, attackers get encrypted blobs. Even if served a warrant, we can only provide encrypted data we cannot decrypt.
Todoist: personal task security controls.
Todoist publishes TLS for data in transit, encryption at rest for most stored user data, AWS hosting, SOC 2 messaging for Business, and restricted staff access. This is conventional SaaS security rather than zero-knowledge content encryption.
Result: Provider-side compromise or authorized access paths could expose plaintext content. Todoist can process content for sync, reminders, AI features, support, and lawful data requests where it is technically able to access that content.
Frequently asked questions.
Is Todoist end-to-end encrypted?
No. Todoist publishes TLS for data in transit and encryption at rest for projects, tasks, comments, account information, payment information, and newer file uploads. It is not zero-knowledge end-to-end encryption, so the service can process workspace content to operate product features.
Can Todoist employees see my data?
Todoist says staff access to personal data is restricted to a small number of employees who need access for specific reasons. That is still an authorized server-side access model, not a design where the provider lacks decryption capability. Worklist cannot access encrypted workspace content because we do not have the keys.
Does Todoist use my data for AI training?
Doist says its AI providers do not train on user data and that AI models run on infrastructure Doist controls. Todoist Assist can still use the context of your request and relevant account information when AI features are used. Worklist cannot process encrypted workspace content with server-side AI because we cannot decrypt it.
Can I use Todoist or Worklist for HIPAA-regulated PHI?
Do not treat either product as HIPAA-ready by default. Worklist's zero-knowledge design may help with technical safeguards, but PHI requires a written compliance agreement or BAA with Worklist. Todoist currently says it has not yet pursued HIPAA certification.
Which is better for simple task management?
Todoist is excellent for personal productivity, quick capture, reminders, calendar views, and lightweight team tasks. Worklist is better when the shared task workspace contains confidential client work, legal matters, healthcare operations, financial planning, or other sensitive team content.
