Terms of Service

KDAN PDF Reader and KDAN Office (collectively “KDAN Document Solution”) were developed by KDAN Software Ltd. Users shall read the following Terms of Service carefully before using KDAN Document Solution.

1. Membership and Registration


By registering for membership with KDAN Software Ltd. (“Kdan”) or using KDAN products and KDAN services and features (collectively “KDAN Services”), you (“User”) are agreeing that these Terms of Service will apply and that you are bound by them (“Agreement”).


Membership registration is free of charge. User may apply for new accounts via valid emails or through social media accounts including Facebook, Twitter, LinkedIn, Google, WeChat, QQ, Apple, and Microsoft, or through other platforms or methods approved by KDAN at the time of application for membership registration. In the event that the email or social media accounts used by User for membership registration is/are found to be invalid, User agrees that KDAN shall have the right at its sole discretion to suspend such User’s KDAN account and/or delete or remove any and all files stored under such account without any liability. If User encounters subscription or payment refund problems that result from using invalid email or social media accounts, further processing will take place only if User has resubmitted and verified a valid email or social media account with confirmation that such resubmitted account belongs to the User who has submitted the complaint. User is deemed to have agreed to receive any emails or newsletters that will be sent by KDAN upon making an application for KDAN membership registration. User will be charged only for and when subscribing to and purchasing KDAN Services.


User must meet the age restrictions of the country/region in which he or she is located in order to use KDAN Services. If User in his or her country/region is a minor or a person of no capacity or limited capacity to perform juridical acts, User must obtain permission from his or her parent or legal guardian in order to use KDAN Services and accept this Agreement. If User is a person of no capacity to perform juridical acts, User’s legal guardian must apply for membership registration or pay for purchases on behalf of User in order to use KDAN Services and accept this Agreement.



2. Services


User must access or download KDAN Services through legal means authorized by KDAN. Certain KDAN products can be used without membership registration while other KDAN Services require membership registration before using the services included in the product.


If a KDAN product purchased by User is packaged with a cloud storage service, User will enjoy free cloud storage space (hereinafter referred to as “Cloud Storage Space,” but which differs from the “KDAN CLOUD” service). Certain KDAN products, however, do not include the Cloud Storage Space.


If User wishes to use the KDAN CLOUD service, User must register as a KDAN member and log in to the account before using the service. User will be offered extra KDAN CLOUD space for free with a certain amount of storage capacity after completing the membership registration process (capacity of the free storage space is subject to relevant KDAN announcements or terms of service).



3. Application


The KDAN CLOUD membership account is the same as the account for other KDAN Services. Any of the KDAN Services that supports KDAN CLOUD is compatible with and can be linked to KDAN CLOUD. However, not all products or services offered by KDAN are compatible with or can be linked to each other. KDAN is committed to continually providing products and services to User to optimize the user experience.

KDAN provides the following subscription models for a specified period to be determined by KDAN for accessing and using KDAN Services.

Without the prior consent of KDAN, you may not sublicense or transfer the permanent license to any third party or transfer it to other unauthorized devices.


The permanent licensing option provides technical support and security updates for KDAN products for a certain period. However, by the technical support and security updates abovementioned, you will not receive any new functions or features of KDAN products, nor will you be able to upgrade KDAN products to major versions. KDAN reserves the right to modify, update, or terminate KDAN Services (including any part or feature of it) at any time, without holding responsible for any liability to you or any other party. Yet, for any changes of the paid products, KDAN will provide reasonable notice in advance. If KDAN completely terminates the KDAN Services, KDAN will also make reasonable commercial efforts to allow you a reasonable time to transfer your content and information.


• After the modifications, updates, or termination of KDAN Services, KDAN will no longer provide technical support and security updates on it. Please note that the cessation of technical support and security updates by KDAN will not affect the usability of KDAN products; however, the compatibility of the application (e.g., hardware, operating system matching) may be impacted.


• If you intend to upgrade the KDAN products to the major version, you must purchase the software at its full price.


Users can apply for the “Permanent License Free Trial Program” for certain KDAN products through the official website of KDAN or redeem it via the KDAN Creative Store. This program allows users to utilize and experience the paid features of KDAN products.


When the “Permanent License Free Trial Program” expires, if the KDAN product offers a free version of the service, the product will automatically downgrade to the free version, and users will be able to continue using the services provided under the free version. If the KDAN product is a paid product, users will no longer be able to use the product.


(3) Cancelation of Permanent License


If you purchased the permanent licensing option of KDAN products through a third-party platform (such as through the App Store or Microsoft Store), please follow the refund standards and procedures of each platform; for purchases which made through the KDAN Creative Store website, the refund standards and procedures of KDAN are as follows:
