These Terms and Conditions ("Terms") govern your installation and use of the Nine email and productivity applications identified below (collectively, "Nine" or the "App") provided by JiranSoft Co., Ltd. ("JiranSoft," "we," "us," or "our"). By installing or using Nine, you agree to these Terms, to the extent permitted by applicable law.
If you use Nine on behalf of an organization, your organization’s applicable IT policies and agreements with JiranSoft or a distributor may also apply. In the event of a conflict, an individually negotiated written agreement prevails to the extent of that conflict.
These Terms apply, as applicable, to Nine – Email & Calendar and enterprise-managed editions historically distributed under names including Nine Work for Android Enterprise, Nine Work for AirWatch, Nine Work for Intune, Nine Work for Rubus, and Nine Work for MobileIron AppConnect, insofar as those editions remain available or supported.
Availability of a particular edition, integration, or feature may vary. Mention of a historical edition does not mean that it is currently offered or maintained.
Subject to these Terms and any applicable purchase or enterprise licensing arrangements, JiranSoft grants you a limited, non-exclusive, non-transferable license to install and use Nine on compatible devices for your personal or authorized business purposes.
Nine is proprietary software except for separately licensed third-party components. These Terms do not grant you ownership of Nine, its source code, trademarks, or other intellectual property. Rights granted under applicable open-source licenses remain unaffected.
Nine operates primarily as an on-device email and personal information management client. To use it, you must have an account with a compatible email or other service provider and any permissions required by that provider or your organization.
Nine connects to your organization’s or provider’s servers under their applicable authentication, security, and access policies. JiranSoft does not control third-party servers, account availability, security requirements, or changes to supported protocols. Your service provider may restrict or discontinue access independently of Nine.
You are responsible for maintaining appropriate account credentials, device security, backups where available, and compliance with your organization’s security policies.
If your edition of Nine requires purchase, activation, or enterprise authorization, use is subject to the purchase terms disclosed at the time of the transaction and any applicable store, reseller, or organizational agreement.
Prices, refund eligibility, license restoration, and transferability are governed by the applicable purchase channel and mandatory consumer protection laws. These Terms do not create a new subscription plan or alter a license you previously acquired.
JiranSoft may provide maintenance updates, security fixes, or compatibility improvements at its discretion. Unless expressly agreed in writing, we do not guarantee a specific update schedule, the continued availability of any feature, or compatibility with future operating systems and third-party servers.
Changes in Microsoft Exchange, Microsoft 365, Google, device vendors, mobile operating systems, or enterprise management systems may affect functionality. We may modify or discontinue features or support where reasonably necessary, subject to applicable law and any binding contractual obligations.
For technical support, contact support@officemail.io. Support availability and response times are not guaranteed unless specified in a separate support agreement.
You must use Nine lawfully and in accordance with the rights granted to you. Except where applicable law or an applicable third-party open-source license permits otherwise, you may not distribute unauthorized copies, bypass license controls, or reverse engineer, decompile, or modify proprietary portions of Nine.
You must not use Nine to gain unauthorized access to accounts, networks, or information or to interfere with the operation or security of services.
Our collection and handling of personal information are described in the Nine Privacy Policy, which should be read together with these Terms. Nine stores and processes email and related account data primarily on the device rather than hosting your email content as a JiranSoft cloud mailbox service.
If you do not wish to send diagnostic information, open Settings > Terms & Policies > Report diagnostic info and select No thanks. Support communications and any diagnostic materials you send may be retained in the customer support system to manage your inquiries; you may request deletion by contacting support@officemail.io, subject to applicable legal retention requirements.
Nine may interoperate with third-party email providers, device platforms, and enterprise management solutions. Those services are subject to their own terms, policies, availability, and technical restrictions.
Portions of Nine may incorporate third-party open-source components, including components licensed under the Apache License, Version 2.0. Such components are governed by their respective licenses, which take precedence over inconsistent provisions of these Terms for those components. Applicable copyright and attribution notices must be preserved.
Portions of Nine are based on work created and shared by Google. Nine uses Microsoft® Exchange ActiveSync® technology licensed from Microsoft where applicable. Microsoft and Exchange ActiveSync are trademarks of the Microsoft group of companies. Other names may be trademarks of their respective owners. These statements do not imply that Nine currently supports Google OAuth2 or the Gmail API.
Except as expressly indicated for third-party materials, Nine and related documentation are protected by intellectual property laws. © 2026 JiranSoft Co., Ltd. All rights reserved, subject to the rights of third-party licensors and any pre-existing copyright ownership.
Historical copyright notices identifying prior rights holders must not be removed from third-party components or other material for which those notices remain legally required.
To the maximum extent permitted by applicable law, Nine is provided on an “AS IS” and “AS AVAILABLE” basis, without warranties of uninterrupted operation, error-free performance, or fitness for a particular purpose. JiranSoft does not warrant the availability or conduct of independent email or platform providers.
Nothing in these Terms excludes any warranty, remedy, or consumer right that cannot lawfully be excluded.
To the maximum extent permitted by applicable law, JiranSoft shall not be liable for indirect, incidental, special, consequential, or punitive damages, or loss of profits or business opportunities arising from use of or inability to use Nine. This limitation does not apply to liability that cannot lawfully be limited, including liability for intentional misconduct or gross negligence where applicable.
Nothing in this section limits any statutory rights or remedies that cannot be excluded under applicable law.
We may revise these Terms to reflect legal, technical, or operational changes. The revised version will be made available through the App or an official publication channel with an updated effective date. Where applicable law requires advance notice or consent, we will follow those requirements.
Changes do not retroactively remove rights under completed purchases or override existing written agreements except as lawfully permitted.
These Terms are governed by the laws of the Republic of Korea, without prejudice to mandatory consumer protection rules that apply in your place of residence. Disputes shall be handled by courts having jurisdiction under applicable law.
If a provision is held unenforceable, the remaining provisions remain in effect to the extent allowed by law.
