Nyan Streaming Japan Privacy Policy

Nyan Streaming Japan is a service for broadcasting and watching video and audio. User recording, file uploads and paid-plan purchases are unavailable, but the operator may record streams to check music use.

This policy explains how KuronekoServer handles information in Nyan Streaming Japan broadcasts, viewing and dashboards. See our operator information for our address and responsible operator.

1. Information and purposes

1. Account details: name/display name, email and verification status, image, language, account reference number, external sign-in details, sign-in times, IP addresses and device/browser type. If several people manage the service together, we also handle group names, members, invitations and information about the people managing it. These support sign-in, settings, notifications and abuse prevention. Information from previous sign-in methods may remain.
2. Stream settings: stream keys, external app connection details, viewing passwords, destinations and video, audio or viewing restrictions. We use them to start broadcasts, verify viewers, adjust video/audio and restream to your chosen destinations.
3. Connections and usage: publisher and viewer IP addresses, connection destinations and methods, usage times, traffic, video quality, viewer counts, delays and errors. We use these to deliver streams, manage usage limits, compile statistics and investigate faults or misuse.
4. Video and audio: live video and audio are processed to deliver streams. People who know a viewing URL may be able to access content. User recording and file uploads are unavailable, so we do not collect storage information through those actions.
5. Operations and billing: usage, setting changes, abuse or violation responses, and inquiry content and attachments support service management, security, responses and investigations. We do not collect paid-plan purchase information. Additional royalties may require billing contacts, usage records, calculation basis, amounts, payment deadlines, payments and objection records.
6. Music use: reporters, organizations, streams, works, artists/rightsholders, work codes, usage dates/counts, review status, necessary administrative recordings and additional royalty calculation/billing/payment records support usage verification, licensing, reporting, billing and objections.

We use KRNK ID for sign-in and receive account information such as user ID, name/display name, email, image and language to recognize your account. Information registered with KRNK ID itself is described in the KRNK ID Privacy Policy.

2. Recordings and music review

User recording and storage features are unavailable. We may record stream video and audio as necessary to identify music, verify usage and investigate rights infringement. These recordings are not for public release or user archives and are handled only by designated staff.

Using music reports submitted through the dashboard and staff review, we may report work titles, authors, artists, usage months/counts and other required details to NexTone and JASRAC. Routine reports do not include recordings themselves. Disclosure of recordings to rights holders is limited to what is necessary with consent or another applicable legal basis.

3. Diagnostics and cookies

To investigate problems and improve quality, we may use Sentry to record errors, performance and dashboard activity such as navigation and clicks. We mask text and input and restrict recording of video, audio and information such as stream keys. These activity records are separate from broadcast recordings. Service access and error records also support operation and troubleshooting.

Cookies and similar storage support sign-in, authentication protection and language preferences. Blocking or deleting site data may prevent sign-in or preference persistence. We do not sell personal information or use collected data for advertising tracking.

4. Retention and deletion

Stream statistics are deleted periodically according to retention settings. Account, settings, activity, error and inquiry records are retained as needed for service provision, security, legal obligations, abuse investigations and disputes.

Music reports and operator recordings are retained only as reasonably necessary to complete quarterly reporting and required checks or investigations. Additional royalty billing and payment records are kept as needed for accounting and disputes. Unnecessary information is deleted or anonymized. Backups, deletion processing and legal retention duties may affect when deletion takes effect.

5. External services, recipients and overseas processing

We use server and storage providers such as Cloudflare for operation and data storage, KRNK ID for sign-in and Sentry for troubleshooting. Storage providers such as Bunny may hold operator recordings. Providers receive connection information, stored data or recordings as needed for their purposes. Email providers receive recipients and notification content. Restream destinations you choose receive video, audio and connection information.

If you manage the service with others, people managing or belonging to the same group may be shown profiles, settings, usage and content. We engage and supervise processors as necessary. Other disclosures require user instructions, consent or a legally permitted basis. External services may process data outside Japan. Overseas transfers use required disclosures, consent or legally compliant safeguards; beginning use is not blanket consent.

We manage information for this Service separately from other services. Storage and processing locations depend on the external services used.

The following official privacy policies also explain how these external providers handle information themselves. Cloudflare / Bunny

6. Security and choices

We work to prevent leaks and misuse by limiting staff access, checking sign-ins, disabling exposed stream keys and encrypting connections. Some streaming methods may not encrypt communications. Choose a supported secure connection method and protect stream keys, viewing URLs and similar information.

7. Rights, contact and changes

Request disclosure, notification of purposes, third-party provision records, correction, deletion, suspension of use or third-party disclosure at support[at]krnk.org (replace [at] with @). We verify identity using account and usage details and respond under applicable law. We explain refusals, including retention obligations. Deleting a sign-in account does not automatically delete every Service record. Minors must obtain legally required guardian consent. Material changes and their application date will be announced, with consent where required.
