0) Summary (non-binding)

Yoyatta is scheduling software. Hosts make calendars; Bookers reserve time. We provide tools and optional integrations (e.g., Zoom/Teams/Meet/Webex). We are not a party to any meeting and we do not verify the truth or accuracy of bookings, calendars, titles, descriptions, identities, availability, or meeting links. We are not responsible for no-shows, lateness, cancellations, meeting quality, or any outcome of a meeting. Some features are free; paid tiers unlock more. Use must be lawful and respectful. Please read the binding terms below.


1) Agreement & Acceptance

These Terms of Service (“Terms”) form a binding agreement between you and Smart Soft K.K. By accessing or using Yoyatta, you agree to these Terms and our Privacy Policy. If you use the Service for an organization, you represent you have authority to bind it.

Eligibility. You must be at least 13 years old (or the age of digital consent in your jurisdiction) and able to form a contract.


2) Key Definitions

  • Host: Creates and manages a calendar others can book.
  • Booker: Reserves a time slot on a Host’s calendar via web, App Clip, or app.
  • Calendar: A scheduling page with a unique URL/slug that a Host shares.
  • Booking: A reservation for a time slot on a Calendar.
  • Meeting Link: A join URL for Zoom, Microsoft Teams, Google Meet, Webex, or similar.
  • Third-Party Services: Identity providers (e.g., Apple/Google/Microsoft/Slack/GitHub/LINE) and meeting providers (e.g., Zoom/Teams/Meet/Webex).

3) What We Provide (and What We Don’t)

3.1 The Service

We provide software that helps Hosts publish availability and Bookers reserve time. Optional features may include email confirmations, sign-in via third parties, calendar invites, and integrations that create meeting links.

3.2 We Do Not Verify or Guarantee

  • No verification of calendars or bookings. We do not verify the accuracy, truthfulness, legality, availability, timing, or details of any calendar, booking, title, description, pricing, location, meeting link, identity, or intent of any user.
  • No endorsement. Display of any calendar or content is not an endorsement or guarantee.
  • No attendance/outcome guarantee. We are not responsible for no-shows, lateness, cancellations, rescheduling, meeting quality, network issues, recording practices, or any outcome of a meeting.
  • No dispute resolution. Any disputes, refunds, service levels, or deliverables are strictly between Host and Booker.

3.3 Platform Only

We are a software platform. We do not host your meetings, provide professional services, or act as an agent, broker, or insurer for Hosts or Bookers.


4) Accounts & Access

  • Hosts manage calendars through the iOS app (and related interfaces). Keep your devices secure; you are responsible for actions taken under your account.
  • Bookers may authenticate via third-party identity providers; your use of such providers is subject to their terms.
  • We may refuse, reclaim, or change calendar slugs that cause confusion, infringe rights, or violate policy.

5) Plans, Billing & In-App Purchases

  • Free tier: limited features (e.g., one calendar) and sending caps may apply.
  • Paid tiers: additional calendars/features as described in-app.
  • Billing: Subscriptions and payments made through Apple’s App Store are governed by Apple’s terms. Manage or cancel via your Apple ID settings. We do not store your payment card data.
  • Changes: We may change prices or features with notice where required; changes typically apply to future billing cycles.

6) Host Responsibilities

  • Content & rules. You (Host) are solely responsible for your calendar content (titles, descriptions, branding), availability, time-zone settings, meeting links, booking rules (e.g., allow/deny lists, buffers, passcodes), and any communications with Bookers.
  • Compliance. You must follow applicable laws (e.g., consumer, advertising, data protection, and anti-spam).
  • Integrations. If you connect Zoom/Teams/Meet/Webex (or similar), you authorize us to create/update/cancel meetings per your instructions. Availability or performance of third-party services is not guaranteed.
  • No misuse. Do not use Yoyatta to spam, mislead, or collect data unlawfully.

7) Booker Responsibilities

  • Accurate info. Provide accurate information when booking or canceling.
  • Third-party terms. If you use third-party meeting software or sign-in, you are bound by those providers’ terms.
  • Meeting etiquette & safety. Coordinate logistics directly with the Host; we are not involved in meeting processes or outcomes.

8) Acceptable Use

You agree not to:

  • Use the Service for unlawful, harmful, fraudulent, deceptive, or abusive activity;
  • Harass or defame others; upload hate speech, obscene, or illegal content;
  • Circumvent access controls, rate limits, or security features;
  • Interfere with or overload the Service (e.g., scraping that degrades performance);
  • Upload malware or exploit vulnerabilities;
  • Infringe or misappropriate intellectual property or privacy rights.

We may investigate and act (e.g., remove content, throttle, suspend, or terminate access).


9) Third-Party Services & Links

The Service may interoperate with or link to third-party services you choose to use. Those services are governed by their own terms and privacy policies. We do not control or assume responsibility for third-party services, their availability, or their data handling.


10) Privacy & Data

Our Privacy Policy explains what we collect, how we use it, and your choices (e.g., feature-usage analytics, error/crash logging). By using the Service, you acknowledge our Privacy Policy.


11) Intellectual Property; Your Content

  • Ours. The Service (software, designs, logos, and content we provide) is owned by us or our licensors and protected by law. Except as permitted by these Terms, you may not copy, modify, reverse engineer, or distribute it.
  • Yours. You retain rights to content you submit (e.g., calendar titles, descriptions, branding). You grant us a non-exclusive, worldwide license to host, process, transmit, and display that content solely to operate and improve the Service.

12) Feedback

If you send ideas or suggestions, you grant us a perpetual, irrevocable, royalty-free license to use them without restriction or obligation.


13) Beta Features & Changes

Some features may be experimental or in beta and could change or be withdrawn. We may modify or discontinue the Service (or any part) at any time; where required, we will provide notice.


14) Disclaimers

To the fullest extent permitted by law, the Service is provided “as is” and “as available.” We disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, secure, error-free, or that data will not be lost.

Meetings. We do not verify bookings or calendars and are not responsible for any meeting, including no-shows, lateness, cancellations, quality, outcomes, recordings, or communications between Hosts and Bookers.


15) Limitation of Liability

To the fullest extent permitted by law:

  • We are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or lost profits, revenues, or data, even if advised of the possibility.
  • Our total liability for any claim arising from or relating to the Service is limited to the greater of (a) the amounts you paid to us in the 12 months before the event, or (b) JPY 10,000.

Some jurisdictions do not allow certain limitations; where prohibited, these limits apply to the maximum extent permitted.


16) Indemnification

You will defend, indemnify, and hold harmless the Company and its affiliates, officers, directors, employees, and agents from any claims, losses, liabilities, damages, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to (a) your use of the Service, (b) your content, (c) your breach of these Terms, or (d) your violation of any law or third-party right.


17) Suspension & Termination

We may suspend or terminate access if you violate these Terms, pose a risk to the Service or others, fail to pay fees, or if required by law. You may stop using the Service at any time. For App Store subscriptions, manage cancellation through your Apple ID. Sections that by nature should survive (e.g., IP, disclaimers, limitations, indemnity, governing law) will survive termination.


18) Export & Sanctions

You must comply with applicable export control and sanctions laws. You may not use the Service if prohibited by such laws.


19) Governing Law & Venue

These Terms are governed by the laws of Japan (without regard to conflict of laws). You agree to the exclusive jurisdiction of the courts located in Kyoto, Japan, unless another venue is required by mandatory law.


20) Apple & Platform Terms

When you download or use our iOS app/App Clip, you also agree to Apple’s applicable terms (including Apple’s Licensed Application End User License Agreement). Where Apple’s mandatory terms conflict with these Terms for iOS distribution, Apple’s terms control for that context.


21) Changes to These Terms

We may update these Terms from time to time. If changes are material, we will provide notice as required (e.g., in-app or by email). Your continued use after changes take effect constitutes acceptance.


22) Entire Agreement; Miscellaneous

These Terms (and the documents referenced here, such as our Privacy Policy) are the entire agreement between you and us regarding the Service and supersede prior or contemporaneous agreements. If any provision is unenforceable, the remainder remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them as part of a merger, acquisition, or sale of assets.

(Attached) Apple Standard EULA: Apps made available through the App Store are licensed, not sold, to you. Your license to each App is subject to your prior acceptance of either this Licensed Application End User License Agreement (“Standard EULA”), or a custom end user license agreement between you and the Application Provider (“Custom EULA”), if one is provided. Your license to any Apple App under this Standard EULA or Custom EULA is granted by Apple, and your license to any Third Party App under this Standard EULA or Custom EULA is granted by the Application Provider of that Third Party App. Any App that is subject to this Standard EULA is referred to herein as the “Licensed Application.” The Application Provider or Apple as applicable (“Licensor”) reserves all rights in and to the Licensed Application not expressly granted to you under this Standard EULA. a. Scope of License: Licensor grants to you a nontransferable license to use the Licensed Application on any Apple-branded products that you own or control and as permitted by the Usage Rules. The terms of this Standard EULA will govern any content, materials, or services accessible from or purchased within the Licensed Application as well as upgrades provided by Licensor that replace or supplement the original Licensed Application, unless such upgrade is accompanied by a Custom EULA. Except as provided in the Usage Rules, you may not distribute or make the Licensed Application available over a network where it could be used by multiple devices at the same time. You may not transfer, redistribute or sublicense the Licensed Application and, if you sell your Apple Device to a third party, you must remove the Licensed Application from the Apple Device before doing so. You may not copy (except as permitted by this license and the Usage Rules), reverse-engineer, disassemble, attempt to derive the source code of, modify, or create derivative works of the Licensed Application, any updates, or any part thereof (except as and only to the extent that any foregoing restriction is prohibited by applicable law or to the extent as may be permitted by the licensing terms governing use of any open-sourced components included with the Licensed Application). b. Consent to Use of Data: You agree that Licensor may collect and use technical data and related information—including but not limited to technical information about your device, system and application software, and peripherals—that is gathered periodically to facilitate the provision of software updates, product support, and other services to you (if any) related to the Licensed Application. Licensor may use this information, as long as it is in a form that does not personally identify you, to improve its products or to provide services or technologies to you. c. Termination. This Standard EULA is effective until terminated by you or Licensor. Your rights under this Standard EULA will terminate automatically if you fail to comply with any of its terms. d. External Services. The Licensed Application may enable access to Licensor’s and/or third-party services and websites (collectively and individually, "External Services"). You agree to use the External Services at your sole risk. Licensor is not responsible for examining or evaluating the content or accuracy of any third-party External Services, and shall not be liable for any such third-party External Services. Data displayed by any Licensed Application or External Service, including but not limited to financial, medical and location information, is for general informational purposes only and is not guaranteed by Licensor or its agents. You will not use the External Services in any manner that is inconsistent with the terms of this Standard EULA or that infringes the intellectual property rights of Licensor or any third party. You agree not to use the External Services to harass, abuse, stalk, threaten or defame any person or entity, and that Licensor is not responsible for any such use. External Services may not be available in all languages or in your Home Country, and may not be appropriate or available for use in any particular location. To the extent you choose to use such External Services, you are solely responsible for compliance with any applicable laws. Licensor reserves the right to change, suspend, remove, disable or impose access restrictions or limits on any External Services at any time without notice or liability to you. e. NO WARRANTY: YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT USE OF THE LICENSED APPLICATION IS AT YOUR SOLE RISK. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSED APPLICATION AND ANY SERVICES PERFORMED OR PROVIDED BY THE LICENSED APPLICATION ARE PROVIDED "AS IS" AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND, AND LICENSOR HEREBY DISCLAIMS ALL WARRANTIES AND CONDITIONS WITH RESPECT TO THE LICENSED APPLICATION AND ANY SERVICES, EITHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF QUIET ENJOYMENT, AND OF NONINFRINGEMENT OF THIRD-PARTY RIGHTS. NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY LICENSOR OR ITS AUTHORIZED REPRESENTATIVE SHALL CREATE A WARRANTY. SHOULD THE LICENSED APPLICATION OR SERVICES PROVE DEFECTIVE, YOU ASSUME THE ENTIRE COST OF ALL NECESSARY SERVICING, REPAIR, OR CORRECTION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES OR LIMITATIONS ON APPLICABLE STATUTORY RIGHTS OF A CONSUMER, SO THE ABOVE EXCLUSION AND LIMITATIONS MAY NOT APPLY TO YOU. f. Limitation of Liability. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT SHALL LICENSOR BE LIABLE FOR PERSONAL INJURY OR ANY INCIDENTAL, SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES WHATSOEVER, INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, LOSS OF DATA, BUSINESS INTERRUPTION, OR ANY OTHER COMMERCIAL DAMAGES OR LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE LICENSED APPLICATION, HOWEVER CAUSED, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, OR OTHERWISE) AND EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY FOR PERSONAL INJURY, OR OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. In no event shall Licensor’s total liability to you for all damages (other than as may be required by applicable law in cases involving personal injury) exceed the amount of fifty dollars ($50.00). The foregoing limitations will apply even if the above stated remedy fails of its essential purpose. g. You may not use or otherwise export or re-export the Licensed Application except as authorized by United States law and the laws of the jurisdiction in which the Licensed Application was obtained. In particular, but without limitation, the Licensed Application may not be exported or re-exported (a) into any U.S.-embargoed countries or (b) to anyone on the U.S. Treasury Department's Specially Designated Nationals List or the U.S. Department of Commerce Denied Persons List or Entity List. By using the Licensed Application, you represent and warrant that you are not located in any such country or on any such list. You also agree that you will not use these products for any purposes prohibited by United States law, including, without limitation, the development, design, manufacture, or production of nuclear, missile, or chemical or biological weapons. h. The Licensed Application and related documentation are "Commercial Items", as that term is defined at 48 C.F.R. §2.101, consisting of "Commercial Computer Software" and "Commercial Computer Software Documentation", as such terms are used in 48 C.F.R. §12.212 or 48 C.F.R. §227.7202, as applicable.

Unpublished-rights reserved under the copyright laws of the United States. i. Except to the extent expressly provided in the following paragraph, this Agreement and the relationship between you and Apple shall be governed by the laws of the State of California, excluding its conflicts of law provisions.
