The Best To-Do List Apps for Privacy-Conscious Users in 2026

Wirecutter’s annual roundup of to-do list apps is a trusted guide for productivity. But if you care about digital privacy, features and design are only half the picture. This article looks at the privacy and security practices behind the top contenders, so you can choose a task manager that protects your personal information as well as your time.

What happened

In December 2025, The New York Times’s Wirecutter published its review of the three best to-do list apps for 2026. The picks reflected a balance of usability, cross-platform support, and reliability—criteria that help most people stay organized. However, the review did not deeply compare how each app handles your data. That gap matters more now than ever, as concerns about app data collection continue to grow.

Based on the Wirecutter methodology and the apps that consistently rank well, the leading candidates typically include Todoist, Things 3, and Microsoft To Do. (The exact list may have shifted; readers should check the latest update of the Wirecutter article for the current picks.) Each of these apps takes a different approach to privacy and security.

Why it matters

To-do lists often contain highly personal information—medical appointments, financial deadlines, project notes, even passwords. If an app collects this data without strong encryption or shares it with third parties, you’re exposed to privacy risks. Weak account security can also let attackers view or delete your lists. With more people using task managers for work and family coordination, the stakes are higher than many realize.

Three main privacy considerations stand out:

  • Data collection: Some apps gather usage analytics, location data, or even the content of your tasks. This data can be used for advertising, training AI models, or sold to data brokers.
  • Encryption: Not all encryption is equal. End-to-end encryption (E2EE) means only you can read your data. Server-side encryption (in transit and at rest) still allows the provider to access it if compelled.
  • Account security: Two-factor authentication (2FA) and strong password policies are essential. Apps that only offer email-and-password logins are more vulnerable to credential stuffing and phishing.

What readers can do

You don’t need to become a privacy expert to make a good choice. Start with the Wirecutter list, then apply these criteria:

  1. Understand the storage model

    • Local-only apps (like Things 3 for Apple devices) store data on your device. No cloud sync means no server-side risk, but you lose access across devices.
    • Cloud-synced apps with E2EE (such as Todoist’s business tier) encrypt your data before it leaves your device. Only you have the decryption key.
    • Standard cloud apps (like Microsoft To Do) encrypt data in transit and at rest, but the provider holds the keys and can technically access your data.

  2. Check for two-factor authentication
    Enable 2FA wherever it is offered. Todoist, for example, supports 2FA via authenticator apps. Microsoft To Do inherits your Microsoft account’s security settings, which include 2FA. Things 3 does not require an account at all, so no 2FA is needed.

  3. Review the privacy policy
    Look for sections on data sharing, retention, and whether your tasks are used for purposes beyond providing the service. Todoist’s free tier, for instance, collects more data for product improvement than its paid plans. Microsoft’s privacy statement allows data use for “improving products” but not for distinct advertising. Things 3’s policy is minimal because data stays on your device.

  4. Consider cross-platform needs
    If you work across Windows, macOS, Android, and iOS, a local-only app may not work. In that case, a cloud-synced app with E2EE or a provider with a strong privacy track record (such as TickTick, which offers optional E2EE) may be the best compromise.

  5. Turn off optional data collection
    Many apps let you opt out of analytics or usage tracking in settings. Do this immediately after installation.

Recommendation for privacy-conscious users

  • Maximum privacy: Things 3 (Apple ecosystem only). No cloud, no account, no data collection.
  • Best balance for cross-platform users: Todoist with a paid plan that enables E2EE, plus 2FA enabled.
  • Most convenient if you already use Microsoft services: Microsoft To Do. Acceptable as long as you enable 2FA and review the privacy statement—your data will reside in Microsoft’s cloud, but the company does not sell it to third parties.

A final note: privacy policies can change. What is true today may not be true next year. Revisit your app’s privacy settings after major updates, and stay aware of how your data is handled. Your to-do list is yours alone—choose an app that treats it that way.
