These Terms of Service (the "Terms") govern the provision of the service "pencil.in" (the "Service") and the rights and obligations between the operator and users. By using the Service, users agree to these Terms.
The Service is a web application provided free of charge for managing reservations of meeting rooms, facilities, equipment, and similar resources. Users can register spaces and resources on the Service and share reservation information with third parties via share URLs.
Administrative use of the Service requires account authentication via the specified login methods. Viewing or booking through a share URL does not require registration.
Users must not engage in any of the following conduct when using the Service:
Users represent and warrant that they do not fall under, and have no relationship with, any anti-social forces, including organized crime groups, their members or affiliated enterprises, corporate extortionists, social-movement racketeers, special-intellectual-violence groups, or any persons similar to the foregoing (collectively, "Anti-Social Forces").
If a user is found to be, or to have any relationship with, Anti-Social Forces, the operator may suspend or terminate the user's use of the Service without any prior notice.
If a user violates these Terms, or if the operator determines that a user's conduct is inappropriate for the operation of the Service, the operator may, without prior notice, suspend the account, invalidate share URLs, delete registered data, or take any other measures it deems necessary.
Except to the extent required by law, the operator is not liable for any damages arising from such measures.
The operator may change, add to, or suspend the Service without prior notice. Users acknowledge that continued provision of the Service is not guaranteed.
The operator manages data with reasonable care, but is not liable for loss or corruption of user data due to natural disasters, system failures, or similar causes, except where liability cannot be disclaimed by law. Users should back up important data themselves.
All intellectual property rights in the Service — including copyrights, trademarks, logos, software, user interfaces, and screen designs — belong to the operator or its licensors. Users must not reproduce, modify, distribute, publicly transmit, or otherwise use these materials beyond what is expressly permitted by these Terms.
Copyrights in data that users input through the Service (such as reservation details and notes) are retained by the user or their rights holders. However, users consent to the operator using such data to the extent necessary for service provision, incident response, prevention of misuse, and improvement of the Service.
The Service is provided on an "as is" and "as available" basis. The operator makes no representations or warranties, whether express or implied, regarding the Service, including as to availability, security, error-free operation, fitness for a particular purpose, or non-infringement.
To the fullest extent permitted by applicable law, the operator shall not be liable for any indirect, incidental, special, consequential, or lost-profit damages arising out of or in connection with the use of, or inability to use, the Service.
Nothing in these Terms excludes or limits liability for the operator's wilful misconduct or gross negligence to the extent such exclusion or limitation is not permitted under applicable law.
Because the Service is provided free of charge, advertisements (such as Google AdSense) may be displayed. See the Privacy Policy for details on how advertising is handled.
The operator may amend these Terms when deemed necessary. Amended Terms take effect when posted on the Service.
These Terms shall be governed by and construed in accordance with the laws of Japan. Any disputes arising out of or in connection with the Service shall be subject to the exclusive jurisdiction of the court having jurisdiction over the operator's principal place of business as the court of first instance.
