The Best To-Do List Apps of 2026—and How to Keep Your Tasks Secure
Every year, Wirecutter (the product review service owned by The New York Times) publishes its picks for the best to-do list apps. Their 2026 roundup is no exception, covering three apps that stand out for features, reliability, and ease of use. If you follow their recommendations, you’ll probably get a solid tool for managing your daily tasks.
But there is one aspect Wirecutter’s main review tends to treat lightly: privacy and security. To-do list apps live in the cloud. They sync across your phone, tablet, and computer. That means every errand, work deadline, and even your grocery list is stored on a company’s servers. If that data leaks or is sold to third parties, you’ve handed over a detailed map of your life.
Before you install any app, it’s worth understanding what each of the top picks does with your data—and what you can do to protect it.
What Happened
Wirecutter released its annual review of to‑do list apps in December 2025, naming three apps as the best for most people. (The exact apps are described in the full review on the New York Times website.) As with most productivity software, the review focuses on usability, cross‑platform support, and the quality of features like reminders, sharing, and natural language input.
The review likely touches on security at a high level—for example, whether an app supports end‑to‑end encryption or two‑factor authentication—but it does not go deep into each app’s privacy policy or data‑sharing practices. That’s typical for a consumer product roundup, but it leaves a gap for users who want to keep their task data private.
Why It Matters
Task lists seem mundane, but they contain sensitive information: project deadlines, medical appointments, travel itineraries, passwords (if you store them there), and personal notes. If an app’s cloud storage is breached, that information becomes visible to attackers. If the company sells anonymized usage data, third parties can still infer routines.
According to privacy audits published by nonprofits and security researchers, some popular to‑do apps collect more data than necessary—including device identifiers, location, and even the content of tasks for training machine‑learning models. Others rely on third‑party analytics that share your behavior with ad networks.
The Wirecutter picks are likely from reputable companies, but “reputable” does not always mean “private.” For example, an app that offers end‑to‑end encryption (E2EE) protects your tasks even if the company’s server is compromised. Without E2EE, the company itself can read your data.
What Readers Can Do
You don’t need to abandon a great app if it’s not the most private. Instead, take a few proactive steps:
Check the privacy policy for these specific items:
- Does the app collect task content for anything other than syncing? Some apps use your data to improve recommendations or train AI assistants.
- Is data encrypted in transit (TLS) and at rest? Many apps encrypt at rest, but only a few offer true end‑to‑end encryption where the company cannot see your data.
- Does the app share data with third parties for advertising? Look for phrases like “sell your personal information” or “share with analytics partners.”
Enable account security features. Every major to‑do app supports two‑factor authentication (2FA). Turn it on. Also look for PIN lock, fingerprint or face unlock on mobile devices.
Review app permissions on your phone. A to‑do list app should not need access to your contacts, camera, microphone, or location (unless you use location‑based reminders). Check your phone’s settings and revoke anything suspicious.
Avoid using public or shared devices to access your to‑do list. If you do, log out completely and clear local data.
Consider a self‑hosted alternative if privacy is your top priority. Apps like Vikunja or tasks.org allow you to host your own server. They are more work to set up but give you full control over your data.
Even if you stick with one of Wirecutter’s top three, applying these checks will reduce your risk. And if an app doesn’t meet your privacy standards, there are worthy alternatives that do—they just may not appear in a general‑interest roundup.
