The Best To-Do List Apps of 2026 (and Which Ones Keep Your Data Safe)
Choosing a to-do list app is a personal decision. You want something that syncs across devices, handles recurring tasks, and doesn’t get in your way. But there’s another layer that deserves attention: what the app does with your data. Task entries often include personal schedules, project details, health reminders, or confidential work notes. If that information isn’t handled well, it can become a privacy risk.
Wirecutter, the product review division of The New York Times, publishes an annual roundup of the best to-do list apps. Their 2026 edition came out in December 2025 and ranks three apps based on usability and reliability. However, the Wirecutter review focuses primarily on features, not on privacy or security. So if you’re someone who cares about both productivity and protecting your data, you need to look deeper.
Below is a summary of what Wirecutter’s review found, followed by a practical privacy checklist you can apply to any to-do list app.
What Happened
Wirecutter tested dozens of to-do list apps in late 2025. Their top three picks for 2026, in no particular order, are reported to be Todoist, TickTick, and Things 3. (The exact order and picks depend on the version you read; the review notes that these apps remain strong choices for most people.) The evaluations considered ease of use, cross-platform support, task management features, and reliability.
But the review does not dig into how each app handles your data. For example:
- Todoist stores tasks on cloud servers and uses encryption in transit but not end-to-end encryption by default. Its privacy policy allows data sharing with third-party service providers, and the company has faced criticism in the past for unclear data retention practices.
- TickTick offers similar features but has a longer history of data collection concerns, including location tracking and ad-related data usage. Its encryption is transport-layer only.
- Things 3 is Apple-only, which limits its audience. It stores task data locally on iCloud, which uses Apple’s encryption, but the app itself does not add an extra layer of end-to-end encryption.
These points are not widely discussed in the Wirecutter review, and they matter if you regularly use the app for sensitive information.
Why It Matters
A to-do list app might seem low risk compared to a password manager or banking app. But consider what you put in it: meeting notes, personal goals, medication schedules, travel itineraries, or even ideas that later become business projects. This data can reveal a lot about your daily life, habits, and plans.
Recent research has shown that many free productivity apps collect more data than users realize. Some share anonymized (but potentially re-identifiable) data with advertisers or analytics firms. If the app’s security is weak, a data breach could expose your task list to strangers. And because most to-do apps sync across devices, a compromise on one account can spread to all your logged-in devices.
For privacy-conscious users, the default choice should be an app that minimizes data collection, uses end-to-end encryption, and gives you control over how long your data is stored.
What Readers Can Do
If the Wirecutter picks appeal to you, here are concrete steps to evaluate them for your own privacy needs:
Check the encryption model. Look for “end-to-end encryption” in the app’s security documentation. If the app stores your tasks on its servers but holds the encryption keys, the company can read your data. Apps like Standard Notes (not a to-do app but a notes app) and some task managers such as Toodledo offer stronger encryption options.
Read the privacy policy for data sharing. Look for phrases like “we may share your information with trusted third parties” or “for analytics and advertising.” If the app is free, ask yourself how it makes money. Many free apps monetize through data.
Reduce what you store. Even with a secure app, don’t put passwords, financial details, or highly sensitive personal data into task descriptions. Use a dedicated password manager or encrypted notes app for that.
Consider offline-first apps. Apps that store data primarily on your device and only sync when you choose (like Things 3 on iCloud) reduce exposure. The downside is that you lose some collaboration features.
Review the app’s data retention. Some apps let you automatically delete old tasks after a set period. Others keep everything indefinitely. Choose one that aligns with your comfort level.
If you’re willing to trade some features for stronger privacy, you might prefer an app like Orgzit or Amazing Marvin, which offer more control over data handling. However, neither was listed in the Wirecutter top three, so you should test them yourself.
