Terms of Service

These Terms of Service (hereinafter referred to as the "Terms") define the conditions for using the web application and Chrome extension Pomodoro Sync (hereinafter referred to as the "Service") provided by Pomodoro Sync (hereinafter referred to as "we", "us", or "our"). All users (hereinafter referred to as "Users") are required to use the Service in accordance with these Terms.

Article 1 (Application and Consent)

These Terms shall apply to all relationships concerning the use of the Service between the User and us.
By logging into the Service using a Google account and using the Service, the User is deemed to have agreed to these Terms.

Article 2 (Account Management)

Authentication for the Service is conducted exclusively through Google Login via Firebase Authentication.
The User is responsible for appropriately managing the Google account used to log into the Service.
We will consider any actions taken using the Google account logged into the Service as the actions of the User who holds that account. We shall not be held liable for any damages incurred by the User due to the unauthorized use of their account.

Article 3 (Integration with and Reliance on External Services)

The Service operates in integration with external services such as the Todoist API, YouTube API Services, and various Google APIs (for authentication, notifications, analysis, etc.).
The User shall use the Service after agreeing to the terms of service and privacy policies of each respective external service.
We shall not be held liable, nor will we provide refunds or compensation, if all or part of the Service becomes unavailable due to specification changes, outages, termination of service, or API usage restrictions by these external services.

Article 4 (Paid Plans and Payments)

The Service offers a paid plan (subscription). Details regarding the functional differences between the free and paid plans, as well as subscription fees, are specified on the pricing page (/pricing) within the Service.
We use Dodo Payments for payment processing. Users must comply with the terms and conditions set forth by Dodo Payments.
Even if a User cancels their paid plan in the middle of a billing month, no prorated refunds will be issued under any circumstances. Following cancellation, Users will continue to have access to the paid plan features until their next scheduled renewal date.
Cancellation of the paid plan must be performed by the User themselves via the screen designated by us, such as the settings page (/settings) within the Service. Requests for cancellation made via inquiry forms or external communities (such as Discord) will not be accepted as official procedures.

Article 5 (Data Handling, Disclaimer of Warranties, and Limitations of Liability)

The Service is provided on an "As-Is" basis. We offer this tool for casual use and explicitly disclaim all warranties regarding the following matters. Please be aware of this before using the Service:

No Guarantee of Data Accuracy or Completeness: We do not guarantee strict accuracy or completeness regarding the timer's tracked duration, task-switching operations, or time-spent records captured by the browser extension.
Management of Confidential Information: While the Service retrieves and displays text data such as Todoist task names, we do not apply advanced encryption processing to this string data. Users are responsible for ensuring that highly confidential or sensitive information is not included in task names or similar fields.
Data Loss: Even if information saved in the Service's database (including user settings, accumulated time, graphs, and other statistical data) is lost due to system malfunctions or other reasons, we shall not be responsible for data recovery or liable for any resulting damages. (Note: Regarding integrated Todoist data, the Service only updates the "completed / uncompleted" status of tasks; it will never delete tasks or overwrite task names.)

Article 6 (Sharing Features and Exemption from User Disputes)

The Service provides features such as sharing timers via unique URLs, publicizing BGM (YouTube playlist URLs), and a ranking system using nicknames.
YouTube playlist URLs registered by a User are automatically made visible to other users associated only with their nickname.
When registering a nickname or sharing URLs, the User must not include personal information, defamatory content against others, or content offensive to public order and morals. If we determine content to be inappropriate, we reserve the right to modify or delete such data without prior notice.
We assume no responsibility and are under no obligation to intervene in any disputes that arise between Users or between a User and a third party through these features.

Article 7 (Use of Community Features and Disclaimers)

We may provide a community environment (e.g., establishing a Service channel within a Discord server operated by us; hereinafter referred to as the "Community") as a space for user support and interaction via external services (like Discord).
The Community is strictly a venue for voluntary interaction and supplementary support. Official inquiries regarding the Service (such as refund requests, payment issues, or personal data handling) must be made through the designated Google Form or email. Requests made within the Community will not be accepted as official procedures.
We assume no responsibility and are under no obligation to intervene in any disputes that arise between Users or between a User and a third party within the Community.
Users must not engage in remarks offensive to public order and morals, slander against others, or any other actions we deem inappropriate within the Community. If we (including server administrators) determine that a User's statements fall under these categories, we reserve the right to kick or ban (expel or block access) the User without prior notice.

Article 8 (Intellectual Property Rights)

All intellectual property rights and all other rights pertaining to the programs, designs, UI, text, and other elements that make up the Service belong to us or to the entities that have granted us licenses.

Article 9 (Prohibited Acts)

Users must not engage in any of the following acts when using the Service:

Acts that violate laws, regulations, or public order and morals.
Acts related to criminal activity.
Acts that destroy or interfere with the functionality of our servers or networks.
Acts of logging into the Service using another User's Google account.
Acts that may interfere with the operation of our Service.
Acts of collecting or accumulating personal information concerning other Users.
Acts of impersonating other Users.
Acts that cause trouble between Users, such as harassment or slander against other Users.
Any other acts that we deem inappropriate.

Article 10 (Suspension or Termination of Service Provision)

If we determine that any of the following circumstances exist, we may suspend, interrupt, or terminate the provision of all or part of the Service without prior notice to the User. We shall not be liable for any damages incurred by the User as a result.

When performing maintenance, inspection, or updating of the computer systems related to the Service.
When it becomes difficult to provide the Service due to force majeure, such as earthquakes, lightning strikes, fires, or power outages.
When a system failure or similar issue occurs in the integrated external services.
In any other cases where we determine that it is difficult to continue providing the Service.

Article 11 (Notices and Communications)

Notices to Users regarding the Service (including changes, suspensions, or termination of the Service) will generally be provided via postings within the Service or announcements on the Service's website.
Because we do not store or utilize email addresses for account authentication purposes, we generally will not send individual emails or notifications to specific Users. However, this does not apply when we deem it necessary, such as when replying to an inquiry (e.g., via Google Forms) submitted by a User.

Article 12 (Prohibition of Assignment of Rights and Obligations)

The User may not assign or pledge their position under the usage agreement or their rights or obligations based on these Terms to a third party without our prior written consent.

Article 13 (Handling in the Event of Business Transfer)

If we transfer the business related to the Service to another company, we may transfer the position under the usage agreement, the rights and obligations under these Terms, and the User's registered information and other customer data to the assignee of the business transfer. The User shall be deemed to have agreed in advance to such transfer in this paragraph.

Article 14 (Severability)

Even if any provision of these Terms or a part thereof is determined to be invalid or unenforceable under laws or regulations, the remaining provisions of these Terms and the remaining portion of the provision deemed partially invalid or unenforceable shall continue in full force and effect.

Article 15 (Changes to the Terms of Service)

We may change these Terms at any time when we deem it necessary. The modified Terms shall become effective from the time they are posted on the Service, and Users who use the Service after the modification shall be deemed to have agreed to the modified Terms.

Article 16 (Governing Law and Jurisdiction)

The interpretation of these Terms shall be governed by the laws of Japan.
In the event of a dispute regarding the Service, the Kumamoto District Court shall be the exclusive court of first instance.
