2calendars

Terms of Service

Effective date: June 15, 2026 · Last updated: June 15, 2026 · Version 1.0

These Terms of Service govern your access to and use of 2calendars, a calendar synchronization service operated by Q2A Co., Ltd. (Q2A株式会社), incorporated in Japan with headquarters in Tokyo.

For purposes of these Terms, “2calendars,” “we,” “us,” and “our” refer to Q2A Co., Ltd. “you” and “your” refer to the person or organization accessing or using the Service.

By creating an account, connecting a calendar, starting a trial, subscribing to a paid plan, or otherwise using the Service, you agree to these Terms. If you do not agree, you must not use the Service.

1. The Service

2calendars is a privacy-focused software-as-a-service product that mirrors calendar availability and events between Google Calendar accounts you authorize. The Service allows you to connect Google Calendar accounts, create one-way or two-way synchronization connections, mirror events as private “Busy” blocks or with custom titles, define synchronization rules, and manage your sync configuration.

The Service is currently offered as a beta service. Features may be incomplete, modified, suspended, or discontinued at any time without a service-level agreement, uptime commitment, or performance guarantee unless separately agreed in writing.

2. Important Synchronization Disclaimer

Calendar synchronization involves technical risks. You understand and agree that synchronization may be delayed, interrupted, incomplete, or inaccurate; events may be missed, duplicated, or incorrectly modified; and factors such as time zones, Google API behavior, revoked authorizations, rate limits, or service outages may cause unexpected results.

You must not rely on 2calendars as your sole system for emergency, medical, legal, financial, safety-critical, or other high-risk scheduling. You are responsible for independently verifying important appointments and availability.

We are not responsible for any loss or consequence arising from synchronization failure, delay, or error, including missed meetings, duplicate bookings, deleted events, or inaccurate availability.

3. Eligibility

You may use the Service only if you are at least 18 years old, or if under 18, only with the consent and supervision of a parent or legal guardian who agrees to these Terms on your behalf.

You must have legal capacity to enter into these Terms, be authorized to connect each Google account and calendar you link, and comply with all applicable laws.

If you use the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

You may not use the Service if we previously suspended or terminated your account for violation of these Terms.

4. Corporate Accounts and Company Policies

You are solely responsible for determining whether you are permitted to connect any employer-owned, client-owned, school-owned, or organization-owned Google account to the Service, and for complying with all applicable employer policies, confidentiality obligations, employment agreements, and internal rules.

We do not verify such compliance and are not responsible for any disciplinary action, contract breach, data exposure, or other consequence arising from your decision to connect corporate or organizational accounts.

5. Accounts and Authentication

To use the Service, you may need to create an account and authenticate using Google OAuth. You do not provide your Google password to 2calendars.

You agree to provide accurate account information, keep your credentials secure, not share your account, and be responsible for all activity occurring through your account. Please notify us promptly if you believe your account has been compromised.

6. Google Calendar and Third-Party Services

The Service depends on Google Calendar, Google OAuth, Google APIs, Google Cloud, and other third-party services. Google is not responsible for 2calendars and does not sponsor or endorse it. Your use of Google services is governed by Google’s own terms and policies.

Changes to Google APIs, permissions, or service availability may affect the Service. Revoked OAuth permissions, suspended Google accounts, or Google outages may cause synchronization to stop or fail. We are not responsible for failures caused by Google or other third-party services.

Our use of Google user data complies with the Google API Services User Data Policy, including applicable limited-use requirements. Additional details are in our Privacy Policy.

7. Calendar Data and User Content

“User Content” means calendar-related data and other information that you authorize the Service to access, process, store, transmit, write, update, or delete — including event titles, descriptions, times, locations, attendee information, and other calendar data.

You retain ownership of your User Content. You grant us a limited, non-exclusive license to access and process User Content only as necessary to provide the Service, apply your synchronization rules, troubleshoot, maintain security, comply with law, and enforce these Terms.

You represent that you have the necessary rights and permissions to connect each calendar and that your use of the Service does not violate any law, contract, confidentiality obligation, or third-party right.

8. Sensitive Information

Calendar events may contain sensitive information. You are responsible for deciding which calendars to connect, whether to copy full event details or use private “Busy” blocks, and what synchronization rules to configure. If you copy full details, event information may become visible in the destination calendar according to that calendar’s sharing settings.

You must not use the Service for high-risk scheduling where synchronization failure or inaccuracy could cause serious harm, such as emergency response, medical treatment, or safety-critical operations, unless separately agreed in writing.

9. Security

We use reasonable technical and organizational measures to protect the Service and your data. However, no internet-based service is completely secure. We cannot guarantee absolute security, and you provide and use information at your own risk. You are responsible for maintaining the security of your own devices, accounts, and Google accounts.

10. Synchronization Rules and Mirrored Events

The Service may allow you to configure synchronization rules to exclude, modify, or privatize certain events. You understand that rules may not always operate as expected, may conflict with each other, or may fail if event text changes. Manually editing or deleting mirrored events may interfere with synchronization.

We are not responsible for double bookings, missed meetings, or other losses caused by synchronization rules, delays, failures, or conflicts.

11. Disconnection, Cancellation, and Account Deletion

There are important differences between cancelling a paid subscription, disconnecting a Google account, deleting a synchronization connection, and deleting your 2calendars account.

11.1 Cancelling a Subscription

Cancelling stops future renewals. Unless otherwise stated, you may continue to access paid features until the end of your current billing period. Cancellation does not automatically disconnect your Google accounts, delete connections, or remove mirrored events.

11.2 Disconnecting Google Accounts and Deleting Connections

Disconnecting a Google account stops future synchronization for that account but does not automatically remove already-created mirrored events. Deleting a synchronization connection stops that connection from creating future mirrored events. You may need to manually delete mirrored events from Google Calendar.

11.3 Deleting Your Account

Deleting your account removes your 2calendars account and synchronization configurations. However, mirrored events already in Google Calendar are not automatically removed, and we may retain certain records as described in our Privacy Policy.

12. Plans, Trials, Fees, and Billing

The Service offers free and paid plans. Current offerings may include a free plan with limited synchronization connections and a paid Pro plan with additional features.

12.1 Subscriptions and Billing

Pro plan subscriptions renew monthly and are billed in advance. Subscriptions continue until cancelled. Cancellation stops future renewals; access continues through the end of the paid billing period. Partial-month refunds are not provided unless required by law.

12.2 Trials

We may offer a free trial for the Pro plan. Trial terms, eligibility, and whether the trial converts to a paid subscription will be disclosed at sign-up. Only one trial is generally available per user. You must not abuse trials by creating multiple accounts or using other means to obtain repeated free access.

12.3 Payment, Taxes, and Failed Payments

Payments are processed by Stripe. You must provide accurate billing information and keep your payment method current. Prices may not include taxes; you are responsible for applicable taxes. If payment fails, we may retry the charge, notify you, suspend paid features, or terminate your subscription after reasonable notice.

12.4 Price Changes

We may change prices or plan limits. For existing paid subscriptions, material price changes will take effect no earlier than your next renewal after notice. Continued use after the effective date constitutes acceptance of the new price.

12.5 Refunds

Fees are non-refundable unless required by law or expressly stated otherwise. Unused time is not credited.

13. Acceptable Use

You agree not to use the Service in a way that is unlawful, fraudulent, or harmful; connect calendars you are not authorized to access; violate privacy, confidentiality, or intellectual-property rights; interfere with or disrupt the Service; bypass access controls or security measures; reverse engineer the Service; scrape or harvest data without permission; resell or sublicense the Service without written authorization; transmit malware; perform security testing without written authorization; or abuse trials, billing, or promotional offers.

We may investigate suspected violations and take appropriate action, including limiting, suspending, or terminating accounts.

14. Beta Service

The Service is provided as a beta product and may contain bugs, be incomplete or unavailable, change without notice, or be discontinued. You use beta features at your own risk. We do not guarantee that beta features will become generally available.

15. Service Changes

We may modify or discontinue the Service or any feature at any time. Where required by law or where changes materially reduce paid functionality, we will provide reasonable notice. We are not liable for modifications, suspensions, or discontinuation of the Service except where prohibited by law.

16. Support

Support is provided by email at [email protected]. Support availability may depend on your plan. No support communication creates a warranty, SLA, or binding operational commitment unless expressly stated in a separate written agreement.

17. Ownership and Intellectual Property

We and our licensors own all rights in and to the Service, including software, interfaces, designs, documentation, branding, and related intellectual-property rights. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal or internal business purposes.

You may not copy, modify, distribute, sell, reverse engineer, or create derivative works from the Service except as permitted by these Terms or applicable law. No rights are granted except as expressly stated.

18. Feedback

If you submit ideas, suggestions, or feedback about the Service, you grant us a worldwide, perpetual, irrevocable, royalty-free license to use and exploit that feedback without restriction or compensation. Feedback is not confidential unless separately agreed in writing.

19. Privacy

Our collection, use, storage, and sharing of personal information is described in our Privacy Policy. You should review the Privacy Policy before using the Service. If there is a conflict between these Terms and the Privacy Policy regarding personal-information processing, the Privacy Policy controls.

20. Confidentiality

If you receive non-public information from us about the Service that is identified as confidential or that reasonably should be understood as confidential, you agree not to disclose it except as required by law or with our written permission.

21. Suspension and Termination

You may stop using the Service at any time. We may suspend or terminate your access immediately, with or without prior notice, for breach of these Terms, payment failure, security or legal risk, or if we discontinue the Service.

Upon termination, your right to use the Service ends and synchronization may stop. We may retain certain records as described in these Terms and the Privacy Policy. Provisions that by their nature should survive termination will survive, including those concerning ownership, payment obligations, disclaimers, limitation of liability, indemnification, and dispute resolution.

22. No Warranties

To the maximum extent permitted by law, the Service is provided “as is” and “as available” without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, availability, uninterrupted operation, security, or data preservation. We do not warrant that synchronization will be real-time, uninterrupted, or error-free, or that data will never be lost or leaked.

Public statements or marketing materials are informational only and do not create warranties or service-level commitments unless expressly included in a separate written agreement.

23. Limitation of Liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including lost profits, data loss, missed meetings, duplicate bookings, unauthorized access, or business interruption, regardless of the legal theory and even if we have been advised of the possibility of such damages.

Some jurisdictions do not allow certain exclusions or limitations of liability. In those jurisdictions, our liability will be limited to the maximum extent permitted by law. Nothing in these Terms excludes liability to the extent prohibited under applicable law, including mandatory provisions of Japanese law.

24. Indemnification

You agree to defend, indemnify, and hold harmless Q2A Co., Ltd., its affiliates, officers, directors, employees, and service providers from and against any claims, damages, losses, costs, and expenses arising out of or relating to your use of the Service, your User Content, your violation of these Terms or applicable law, or any claim that your use of the Service infringes third-party rights.

25. Consumer Rights

Nothing in these Terms limits any rights that cannot be excluded under applicable consumer protection laws, including the Consumer Contract Act of Japan and other mandatory laws applicable to consumers. If you are a consumer, some provisions may not apply to you to the extent prohibited by law.

26. Governing Law

These Terms are governed by the laws of Japan, without regard to its conflict-of-law principles.

27. Dispute Resolution and Jurisdiction

Before filing a claim, you agree to first contact us at [email protected] and attempt to resolve the dispute informally. If the dispute is not resolved within 30 days, either party may bring a claim. The Tokyo District Court shall have exclusive jurisdiction as the court of first instance over any dispute arising out of or relating to these Terms or the Service, unless otherwise required by applicable law.

28. Notices

We may send notices by email, in-product notification, or posting on our website. Legal notices to us must be sent by email to [email protected].

29. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will provide notice by reasonable means. The updated Terms become effective on the date stated. Continued use after the effective date means you accept the updated Terms. If you do not agree, you must stop using the Service before the updated Terms take effect.

30. General

Assignment: You may not assign these Terms without our prior written consent. We may assign them in connection with a merger, acquisition, or sale of assets.

Force Majeure: We are not liable for delay or failure to perform caused by events beyond our reasonable control, including natural disasters, internet outages, Google service outages, or government action.

Severability: If any provision is found unenforceable, it will be modified to the minimum extent necessary or severed, and the remaining provisions remain in effect.

Waiver: Our failure to enforce any provision is not a waiver of our right to enforce it later.

Entire Agreement: These Terms, together with our Privacy Policy and any documents incorporated by reference, form the entire agreement between you and us regarding the Service and replace all prior agreements regarding the same subject matter.

31. Language

These Terms are available in English and Japanese. If there is any inconsistency between the two versions, the Japanese version prevails. In the event of any legal dispute, the Japanese version is the controlling version.
