YURI NO1 (also referred to as “YURI1”) respects users’ privacy and the protection of their personal information.
This Privacy Policy explains how YURI1 may collect, use, retain, and process information when you use websites and related services operated by YURI1 under the yuri1.com domain (collectively referred to below as “the Website”).
By using the Website, you acknowledge that you have read and understood this Privacy Policy.
1. Scope
This Privacy Policy applies to all websites and related services operated by YURI1 under the yuri1.com domain, including its subdomains.
If a specific website or service has its own Privacy Policy, that policy shall take precedence for matters it covers. This Privacy Policy shall continue to apply to any matters not covered by the specific policy.
The Website may contain links to third-party websites, social media platforms, video platforms, or other external services. Once you access a third-party service, the collection and processing of information will be governed by that third party’s privacy policy and applicable rules.
This Privacy Policy does not apply to third-party websites or services that are outside the control of YURI1.
2. Information YURI1 May Collect
Depending on how you use the Website, YURI1 or its third-party service providers may have access to the following types of information:
Information You Voluntarily Provide
This may include:
- Your name or display name provided when contacting YURI1;
- Your email address;
- Messages or other information you voluntarily submit;
- Fan creations or other submissions;
- Other information you voluntarily provide to the Website.
Unless voluntarily provided by the user, the Website generally does not require users to provide unnecessary personal information.
Information Generated When You Use the Website
The Website and the services it uses may automatically generate or collect certain technical information, such as:
- IP address;
- Browser type;
- Device or operating system information;
- Website browsing and usage records;
- Access time;
- Referring page;
- Information generated through cookies or similar technologies.
Such information may be automatically processed by the website platform, hosting provider, analytics tools, or other third-party services used by the Website.
3. How YURI1 Uses Information
YURI1 may use collected information for the following purposes:
- Providing, maintaining, and improving the Website;
- Responding to user inquiries;
- Processing submissions or content voluntarily provided by users;
- Maintaining website security and preventing abuse;
- Analyzing website usage;
- Improving website content and user experience;
- Sending notifications or information requested by users;
- Complying with legal obligations;
- Handling other matters necessary for the normal operation of the Website.
YURI1 will not use personal information provided by users for purposes unrelated to the purpose for which it was collected, unless YURI1 has obtained the user’s consent or applicable law otherwise permits or requires such use.
4. Cookies and Similar Technologies
The Website and the third-party services it uses may use cookies or similar technologies to:
- Keep the Website functioning properly;
- Remember certain user preferences;
- Analyze website traffic and usage;
- Improve website functionality and user experience.
Users may manage, restrict, or delete cookies through their browser settings.
However, disabling certain cookies may cause some features of the Website to function improperly.
Local Browser Storage and Reading Preferences
Certain Website features may use local browser storage to preserve reading progress, display preferences, and other personalized settings.
For Codex reading features, this information is stored locally on the user’s device and browser. It is not uploaded to YURI1-operated servers as part of the normal reading and saving process.
Users may manage or remove locally stored information through the Website’s available features or their browser settings.
Because locally stored information is not automatically synchronized between devices or browsers, users may need to use the Backup Card feature to preserve or transfer their Codex reading data and preferences.
For further information, please refer to the Website’s Backup Card guide.
5. Third-Party Services
The Website may use websites, analytics services, video services, social media platforms, embedded content, or other services provided by third parties.
Such services may collect and process technical data or other information in accordance with their own policies.
For example, the Website may link to or embed videos, social media content, or other external content provided by third parties.
YURI1 does not have complete control over the data processing practices of third-party services. Users should review the applicable privacy policies of those third parties separately.
6. Data Retention
YURI1 retains information under its control only for as long as reasonably necessary to provide services, handle related matters, comply with legal obligations, or resolve disputes.
The retention period may vary depending on the type of information, the purpose for which it is used, and applicable laws.
Information processed or retained by third-party service providers may also be subject to those providers’ own retention policies and applicable legal requirements.
When information held by YURI1 is no longer necessary to retain, YURI1 will, within reasonable limits, delete, anonymize, or cease using such information.
7. Disclosure and Provision of Information
YURI1 does not sell or rent users’ personal information.
YURI1 may disclose or provide personal information where reasonably necessary and permitted or required by applicable law, including in the following circumstances:
- With the user’s consent;
- When necessary to provide the Website or related services;
- When third-party service providers are engaged to assist with website operations;
- When required to comply with applicable laws, judicial proceedings, or lawful requests from government authorities;
- When necessary to protect the rights, safety, or legitimate interests of YURI1, users, or third parties;
- In other circumstances where disclosure or provision is permitted by law.
If third-party services participate in the operation of the Website, their processing of information may also be governed by their own policies.
8. Data Security
YURI1 will take reasonable and practicable measures to protect personal information against unauthorized access, alteration, disclosure, loss, or other improper use.
However, no method of internet transmission or electronic storage can be guaranteed to be completely secure. Accordingly, YURI1 cannot guarantee that information transmitted or stored online will be completely free from unexpected risks.
9. User Rights
Depending on applicable laws, users may have the following rights regarding their personal information:
- The right to request access to or review their personal information;
- The right to request copies of their personal information;
- The right to request supplementation or correction;
- The right to request that the collection, processing, or use of their personal information be stopped;
- The right to request deletion;
- Other rights provided by applicable law.
If you wish to exercise any of these rights, please contact YURI1 through the official contact information provided on the Website.
YURI1 may require certain information to verify the identity of the requester and prevent unauthorized requests for personal information, where permitted or required by applicable law.
10. Age-Related Privacy Considerations
Some works available on the Website may contain psychological thriller, horror, adult-themed, or other content that may not be suitable for all age groups. Even where YURI1 does not subjectively classify a work as NSFW, differences in individual interpretation may give rise to concerns.
Appropriate content notices may be provided where applicable.
The Website does not request personal information from users for the purpose of collecting unnecessary personal data based solely on age.
Where an individual is represented by a legal guardian for privacy-related matters, the relevant guardian may contact YURI1 through the official contact information provided on the Website.
11. Fan Submissions and Public Content
If a user voluntarily submits fan creations, comments, contributions, or other content to YURI1, the user is responsible for ensuring that such content does not contain personal information that should not be made public or private information belonging to third parties.
For information regarding the rights, permissions, and official use of fan creations, please refer to:
Fan Content Guidelines
This Privacy Policy does not replace or supersede those guidelines.
12. Cross-Border Data Processing
Because the Website may use third-party websites, hosting providers, analytics tools, or other technical services located in different countries or regions, some information provided or generated by users may be processed or stored by relevant service providers in other countries or regions.
YURI1 will take reasonable measures to handle such information to the extent required by applicable laws.
13. Changes to This Privacy Policy
YURI1 may update this Privacy Policy due to changes in website functionality, services, applicable laws or regulations, or operating practices.
Updated versions of this Privacy Policy will be published on the Website and will indicate the date of the latest update.
Where there are material changes, YURI1 may notify users through a website announcement or other reasonable means, where appropriate.
