Task Tree Terms of Use

Effective and last updated: July 22, 2026

These Terms of Use (the "Terms") govern use of Task Tree (the "App") and its official distribution and support pages (collectively, the "Service") provided by Paskra (the "Operator"). By using the Service, you agree to these Terms.

1. Application and acceptance

These Terms apply to all relationships between the Operator and users concerning the Service. You accept these Terms when you agree on the initial consent screen or install, launch, or use the App. If you do not agree, do not use the App and remove it from your devices.

Services provided by third parties, including the App Store, Apple Account, iCloud, and GitHub, are governed by their own terms and policies. If these Terms conflict with mandatory law or terms required to use a third-party service, those rules take priority to the extent of the conflict.

2. Definitions

1. "User" means an individual or organization that agrees to these Terms and uses the Service.
2. "User Data" means workspaces, tasks, branch tasks, due dates, recurrence settings, notification settings, and related information that a User enters, pastes, imports, or creates in the App.
3. "Apple Services" means the App Store, Apple Account, iCloud, iOS, and related services provided by Apple.

3. Service description

The App is a tool for organizing a User's work through tasks, branch tasks, due dates, recurrence, notifications, and a board view. The Service does not guarantee achievement of plans, completion of work, accuracy of decisions, or any business, educational, health, or financial outcome.

4. License and rules of use

Subject to these Terms and the App Store terms, the Operator grants the User a limited, non-exclusive, non-transferable, non-sublicensable, and revocable license to use the App on Apple devices controlled by the User. All rights not expressly granted remain with the Operator or their lawful owners.

5. User responsibility and critical uses

Users are responsible for content they enter, paste, import, export, or share and for managing notification and synchronization settings. Users represent that they have the rights, consent, and authority required for that content.

The App must not be used as the sole system for medical care, emergency response, personal safety, legal deadlines, taxes, contracts, payments, critical business deadlines, or any other use where failure or delay could cause serious harm. Important schedules, records, and evidence should be checked against official information, organizational procedures, professional advice, or another reliable method.

6. User Data

Rights in tasks, branch tasks, schedules, and other content entered by a User remain with the User or their lawful owner. The Operator does not use User Data for purposes unrelated to providing the Service. Storage, iCloud synchronization, notifications, clipboard access, and support information are handled as described in the Privacy Policy.

7. Prohibited conduct

Users must not, directly or through another person:

1. Violate law, court or government orders, or public order, or use the Service to prepare, facilitate, commit, or conceal a crime.
2. Enter, import, export, transmit, or share content that infringes another person's copyright, trademark, trade secret, reputation, privacy, publicity, personal rights, or other rights or interests.
3. Access, obtain, change, delete, or synchronize another person's account, device, Apple Account, iCloud data, or App data without authorization.
4. Conduct unauthorized access, exploit vulnerabilities, bypass authentication, usage restrictions, or security controls, tamper with the Service, reverse engineer, decompile, disassemble, bypass debugging protections, or analyze protected components, except where mandatory law expressly permits it.
5. Exploit defects, malfunctions, unreleased features, test settings, or technical limitations to obtain an improper benefit, damage data, or harm the Service or another person.
6. Distribute malware, ransomware, spam, phishing, impersonation, excessive automation, scraping, load testing, or other activity that harms the security, availability, or integrity of the Service, its distribution pages, support channels, or third-party services.
7. Copy, modify, adapt, sell, lend, redistribute, sublicense, commercially host, provide as a service, publish, or make the App or any part of it available to another person without the Operator's prior written approval.
8. Threaten, extort, discriminate against, harass, impersonate, defame, spread false information about, or direct excessive or repeated requests toward the Operator, another User, or any third party.
9. Represent the Service's name, icon, screens, text, or relationship with the Operator in a way that falsely implies affiliation, endorsement, or official status.
10. Attempt, encourage, assist, or evade restrictions on any conduct listed above.
11. Materially harm the safety, rights, reputation, property, or operations of the Service, the Operator, Users, or third parties in a manner inconsistent with the Service's ordinary purpose and conditions.

8. Measures for violations

If the Operator reasonably believes a User has violated these Terms, the Operator may, without prior notice and to the extent reasonably necessary, suspend use, limit support, stop distribution, block access, request removal of relevant content, preserve records, report the matter to Apple or other relevant parties, or disclose information as required by law. The Operator may act immediately where necessary to address danger to life, health, or property, a security emergency, or a legal requirement.

If a User's violation causes the Operator or a third party to incur loss, cost, claim, penalty, or dispute, the User must resolve it at the User's responsibility and expense and compensate the Operator for ordinary and reasonable losses and expenses, including reasonable legal fees, to the extent permitted by law.

9. Notifications, dates, and recurrence

Notifications, date interpretation, and recurring schedules may not operate as expected because of user input, device state, iOS settings, Focus modes, notification summaries, connectivity, time settings, time zones, or operating-system restrictions. The App does not guarantee delivery, accuracy, timeliness, or perfect interpretation of dates.

10. iCloud synchronization and data operations

The App may use iCloud to share task information between devices signed in to the same Apple Account. Synchronization depends on Apple Account and iCloud settings, connectivity, device state, Apple's service status, iCloud capacity, and operating-system behavior. Delays, conflicts, missing updates, duplicates, retained older data, or differences between devices may occur.

11. Export, import, and deletion

The App may export a task structure as text and import it later. Importing may add to existing data and may create duplicates or unintended branches. Users should inspect content before import and take care with personal or confidential information. Deleted data may not be recoverable.

12. Intellectual property

Intellectual property rights in the App, distribution pages, icon, screen layouts, text, software, names, logos, and other parts of the Service belong to the Operator or their lawful owners. If a User provides a feature request, improvement proposal, or other feedback, the Operator may use it to improve the Service without additional payment or obligation to the User. Rights in User Data remain governed by Section 6.

13. Fees, purchases, and refunds

The App's basic features are currently provided free of charge. If paid features, in-app purchases, subscriptions, or one-time purchases are offered in the future, the applicable features, price, payment timing, and other required conditions will be shown in the App or on the App Store before purchase.

Purchases, billing, renewal, cancellation, and refunds are governed by the App Store and Apple's terms. The Operator does not independently guarantee refunds, without limiting any rights required by law.

14. Third-party services

The App may integrate with, refer to, or depend on iOS, iCloud, the App Store, GitHub, and other third-party services or pages. The Operator does not control or guarantee their availability, changes, outages, data handling, or account restrictions.

15. Changes, suspension, and termination

The Operator may change, suspend, or discontinue all or part of the Service as reasonably necessary for maintenance, incident response, security, compliance with law or App Store requirements, changes to third-party services, improvement, or discontinuation. Material changes or planned discontinuation will be announced in advance through a reasonably available method. Advance notice may not be given for urgent security, legal, or incident response.

16. Disclaimer of warranties and liability

The App is provided "as is" and "as available." The Operator does not warrant that the App will meet a User's particular purpose, remain continuously available, be free of defects, retain data, deliver notifications or synchronization accurately at all times, or maintain access to third-party services.

To the extent permitted by law, the Operator is not liable for unfinished tasks, delayed notifications, synchronization failures, data loss, business loss, lost profits, lost opportunities, reputational harm, or indirect, special, incidental, or consequential damages arising from use of or inability to use the App.

17. Limitation of liability

Where the Operator is liable, liability arising from ordinary negligence in breach of contract or tort is limited to the User's actual, ordinary, and direct damages. If paid features exist, and to the extent permitted by law, aggregate liability is further limited to the amount the User actually paid for the relevant feature during the 12 months before the event giving rise to the claim.

This Section and the previous Section do not apply to damage caused by the Operator's intentional misconduct or gross negligence, personal injury, or liability that cannot be limited or excluded under the Consumer Contract Act of Japan or other mandatory law. Nothing in these Terms limits rights that the law gives to a User acting as a consumer.

18. Changes to these Terms

The Operator may amend these Terms under Article 548-4 of the Civil Code of Japan and other applicable law only where the amendment serves users' general interests or is reasonable in light of the need for the change, the appropriateness of the amended terms, the nature of the change, and other relevant circumstances.

The Operator will announce the effective date and contents of an amendment in the App or on an official page before it takes effect. Minor changes, urgent security measures, or changes immediately required by law will be announced as soon as reasonably possible.

19. Severability

If any part of these Terms is held invalid or unenforceable by law or a court, the remaining provisions continue in effect.

20. Governing law and jurisdiction

These Terms are governed by the laws of Japan. To the extent permitted by law, the Tokyo District Court has exclusive jurisdiction as the court of first instance over disputes concerning the App or these Terms.
