Effective date: June 12, 2026 · Last updated: June 12, 2026

Welcome to MatrixDo (the "App"). The App is developed and provided by deepdream ("we," "us," or "our").

These Terms of Service (the "Terms") constitute an agreement between you and us regarding your downloading, installing, registering, signing in to, and using the App. Please read and fully understand all of these Terms carefully before using the App, especially the clauses that exempt or limit liability. By downloading, installing, or using the App, you acknowledge that you have read, understood, and agreed to be fully bound by these Terms. If you do not agree with any part of these Terms, please stop installing or using the App.

1. Definitions

  • App / MatrixDo:The "MatrixDo" task management software developed by deepdream and distributed through channels such as the Apple App Store, and its various versions (including iPhone, iPad, and Mac versions and their desktop widgets, Live Activities, and other extension components).
  • You / User: The natural person who downloads, installs, and uses the App.
  • Pro Membership / Subscription Service: The paid value-added services offered within the App.
  • Service: All features and content we provide to you through the App.

2. Service Content

MatrixDo is a task and time management tool based on the "four-quadrant" (Eisenhower Matrix) methodology, designed to help you prioritize and execute tasks. The main features of the App include but are not limited to:

  1. Task matrix management:Visual management by dividing tasks into four quadrants (green / red / yellow / blue) along the two dimensions of "productivity" and "urgency";
  2. Task creation and editing: Manually create, edit, archive, and delete tasks, and set estimated durations, due dates, and so on;
  3. Execution modes: Focus timers, sprint lists, deep-focus execution interfaces for different quadrants, with support for Lock Screen / Dynamic Island Live Activities;
  4. Output wall and data insights: Display completed tasks and provide analytics such as time allocation, productivity, and active days (some are Pro features);
  5. System integration: With your authorization, two-way sync with the system Reminders app, reading system Calendar events, and quickly creating tasks via speech recognition (some are Pro features);
  6. iCloud sync: After you sign in to iCloud, sync task data across your devices via Apple CloudKit;
  7. Personalization settings: Theme switching, default countdown settings, and so on.

We reserve the right to update, adjust, add to, or reduce the App's features from time to time based on operational needs. The version you actually use shall prevail.

3. Account and Identity

  1. The App does not set up a separate account registration and login system; you can use its core features without providing a username or password.
  2. Some features of the App rely on the Apple ID and iCloud account on your device: the iCloud sync feature requires you to sign in to iCloud; the subscription service is verified and managed through the Apple App Store and the third-party subscription provider RevenueCat.
  3. You should keep your device and Apple ID secure. Based on the App's "local-first" design, the security status of your device directly affects the security of your task data. Please take necessary device security measures (such as a lock-screen passcode, biometrics, etc.) on your own.

4. Subscription Service (MatrixDo Pro)

  1. Paid features: The App offers a Pro subscription to unlock value-added features such as data insights, calendar import, and voice creation. The specific division between free and paid features is subject to what is actually shown in the app, and we may adjust it from time to time.
  2. Subscription plans: The App offers plans including but not limited to: monthly subscription; annual subscription (which may include a free trial of a certain duration). The specific price, duration, and trial eligibility are subject to what is shown on the App Store page at the time you place your order.
  3. Payment and billing: All subscriptions are paid through the Apple App Store. After a subscription purchase is confirmed, the fee will be charged to your Apple ID.
  4. Auto-renewal: Subscriptions have auto-renewalenabled by default. Unless you turn off auto-renewal at least 24 hours before the end of the current subscription period, the system will automatically renew and charge upon expiration. You can view and manage your subscriptions, or turn off auto-renewal, at any time under iOS "Settings → Apple ID → Subscriptions."
  5. Free trial: If you participate in a free trial, any unused portion of the trial will be forfeited when you purchase a subscription (if applicable). Trial eligibility is generally limited by Apple ID (one per user).
  6. Refunds: Because subscriptions are handled by Apple, refund requests must be made through Apple in accordance with Apple's refund policy; we cannot process refunds for you directly.
  7. Restore purchases:After changing devices or reinstalling the App, you can restore your existing subscription benefits via the in-app "Restore Purchases" feature.
