Terms of Service

Last updated: September 28, 2026

These Terms of Service (the "Terms") set forth the conditions for using the booking management service "予約Lite" (the "Service") provided by Ayan Sengupta (trade name: 予約Lite) ("we" or "us"). Businesses that register an account with the Service ("Shops") shall use the Service upon agreeing to these Terms.

Article 1 (Definitions)

1. "Store" means an individual or corporation that registers an account with the Service and uses the Service to accept reservations.
2. "Customer" means a customer of a Store who makes a reservation through the Store's reservation page.
3. "External Services" means third-party services with which the Service integrates, such as LINE, Google Calendar, and Stripe.

Article 2 (Content of the Service and the Company's Role)

1. The Service provides tools that enable Stores to accept and manage reservations from Customers.
2. Contracts relating to reservations are formed between the Store and the Customer, and the Company is not a party to such contracts. The Store shall be responsible for reservation details, the provision of treatments and services, the collection of fees, and the handling of cancellations.
3. The Store shall, at its own responsibility, make the disclosures and take the actions required toward Customers under the Act on Specified Commercial Transactions and other applicable laws and regulations.
4. Information that a Store posts on its reservation page (store name, menu, prices, availability based on business hours, and any phone number the Store chooses to make public) is made available in a form that can be obtained by third parties (including AI services) not only through the reservation page but also through the public API provided by the Company, machine-readable formats for AI agents (such as Markdown), and search engines. Customer information is not provided through these methods. In addition, reservations cannot be created, modified, or canceled via the public API; reservations must be confirmed by the Customer on the reservation page.

Article 3 (Accounts)

1. The Store shall register accurate information and promptly update it in the event of any changes.
2. The Store shall be responsible for managing its login email address, and the Company shall not be liable for any use by third parties.
3. When a Store registers authentication credentials for External Services (such as a LINE channel secret or Google account integration) with the Service, the Store shall comply with the terms of use of such External Services and warrants that it has the legitimate authority to permit such integration.

Article 4 (Fees and Payment)

1. The Service offers a free "Free" plan (accepting up to 15 bookings per month) and a "Pro" plan with unlimited bookings for ¥1,980 per month (tax included). The prices displayed on the Service shall prevail.
2. Fees for the Pro plan are automatically charged each month through our payment processor (Stripe), starting from the date of application.
3. Stores may cancel the Pro plan at any time. After cancellation, the Pro plan remains available until the end of the current billing period, and no prorated refunds will be issued.
4. Costs associated with the use of external services (such as paid LINE Official Account plans and message delivery fees) shall be borne by the store.
5. We may revise fees by giving notice on the Service or to the registered email address at least 30 days in advance.

Article 5 (Prohibited Acts)

When using the Service, stores shall not engage in any of the following acts:

• Acts that violate laws, regulations, or public order and morals, or acts related to criminal activity
• Using reservation holders' information for purposes other than reservations without their consent
• Registering false store information or impersonating a third party
• Placing an excessive load on the servers or networks of the Service or external services, or unauthorized access
• Reverse engineering, reselling, or lending the Service to third parties
• Acts that violate the terms or policies of external services such as LY Corporation, Google LLC, and Stripe, Inc.
• Any other acts that we deem inappropriate

Article 6 (Handling of Reservation Holder Information)

1. Information entered by reservation holders, such as name, phone number, and LINE user ID, is stored and processed by us on the Service based on an entrustment relationship between the store and us.
2. Stores shall comply with the Act on the Protection of Personal Information and use reservation holders' information solely for the purposes of managing and communicating about reservations.
3. Our handling of personal information is governed by our Privacy Policy.

Article 7 (Integration with External Services)

1. Some features of the Service (LINE notifications, Google Calendar synchronization, and payments) depend on external services. Features may be limited due to specification changes, outages, or usage restrictions of external services (such as LINE message delivery limits), and we accept no responsibility for such limitations.
2. Messages sent from a store's LINE Official Account are sent in the store's name. We accept no responsibility for their content or the costs associated with sending them.
3. If the integration with Google Calendar is disconnected (due to revocation on Google's side, expiration, etc.), we will suspend the store's online reservation acceptance until it is reconnected in order to prevent double bookings, and the reservation page will display a notice to that effect prompting visitors to contact the store. We will notify the registered email address, but reconnection shall be performed by the store, and we accept no responsibility for any lost opportunities arising during the suspension.

Article 8 (Changes, Interruption, and Termination of the Service)

1. We may change, add to, or partially discontinue the content of the Service without prior notice to stores.
2. The Company may temporarily suspend the provision of the Service in the event of system maintenance, failures, natural disasters, outages of external services, or other unavoidable circumstances.
3. If the Company terminates the Service, it will, in principle, notify Stores at least 30 days in advance. In such case, Stores shall be responsible for exporting or recording their own reservation data.

Article 9 (Intellectual Property Rights)

Copyrights, trademark rights, and other intellectual property rights relating to the Service belong to the Company or the legitimate rights holders. Rights to store names, menus, images, and other content registered by a Store on the Service belong to the Store, and the Store grants the Company permission to use such content to the extent necessary to provide the Service.

Article 10 (Disclaimer)

1. The Company does not warrant that the Service is free of defects in fact or in law (including with respect to safety, accuracy, completeness, fitness for a particular purpose, security, etc.).
2. The Company will make reasonable efforts to display availability and prevent duplicate reservations, but does not guarantee that reservations will not overlap due to delays in synchronization with external services or other causes.
3. The Company will not be involved in, and assumes no responsibility for, disputes arising between Stores and customers making reservations (such as no-shows or payment issues).
4. If a Store incurs damages due to reasons attributable to the Company, the Company's liability for compensation shall be limited to the amount of usage fees paid by the Store to the Company during the one-month period immediately preceding the month in which the damages occurred. However, this limitation shall not apply in cases of willful misconduct or gross negligence on the part of the Company.

Article 11 (Suspension of Use and Deregistration)

1. If a Store violates these Terms, fails to pay fees, or provides false registration information, the Company may suspend the Store's use of the Service or cancel its registration without prior notice.
2. Stores may cancel their registration at any time. After cancellation, the data of the Store and its customers will be deleted within a reasonable period.

Article 12 (Amendments to the Terms)

The Company may amend these Terms as necessary. Material changes will be announced on the Service or by notice to the registered email address. If a Store uses the Service after an amendment, the Store shall be deemed to have agreed to the amended Terms.

Article 13 (Governing Law and Jurisdiction)

These Terms shall be governed by the laws of Japan, and in the event of any dispute relating to the Service, the Tokyo District Court shall have exclusive agreed jurisdiction as the court of first instance.
