Privacy Policy for the “YRIS 같이보기” (YRIS Watch Together) Chrome extension

Last updated: October 12, 2026 · Extension ID: bfeeeonfknhgbggnaimejilgfcbengpn
Operator: YRIS Operations Team · Contact: yris.anime@gmail.com

This page explains what user data the Chrome extension “YRIS 같이보기” (the “extension”) collects, how we use it, how long we keep it, and with whom we share it. It is part of the YRIS Privacy Policy. The full policy, which also covers the YRIS website, is at https://yris.live/policies/privacy-policy (Korean and English; the Korean text governs).

1. What the extension does

The extension shows a YRIS Watch Together room in Chrome’s side panel, next to a Netflix tab. It works only for users signed in to YRIS.

Playback sync: the room host’s Netflix playback is the reference, and each participant’s Netflix player follows it.
Room chat: messages of up to 200 characters, reporting a message, blocking a member, and “CleanChat”, which hides messages the server marked as profanity (called “Cleanbot” in version 2 of the full policy).
Participants: the participant and viewer lists. The host can remove a participant from the room.
Guide chatbot: a “Chatbot” tab that answers questions about the story of the title, using only YRIS guide content up to the episode the room is watching.
Settings: panel language (Korean or English) and dark mode.

2. Data the extension collects

The extension collects or processes only the data below, and only to provide the features in Section 1. Categories follow the Chrome Web Store’s user data categories.

Category	Data	When and why
Personally identifiable information	Your YRIS member ID (a random identifier, not your email address), nickname, and identification code. To show other participants, the extension also receives their member IDs, nicknames, and identification codes.	When you sign in and when you join a room, to show who wrote each message and who is in the room
Authentication information	The YRIS sign-in cookie `yris_rt`. The extension sends it only to `api.yris.live` to get an access token that is valid for 10 minutes; the server replaces the cookie each time. The access token is sent with each request to YRIS servers.	To carry over the sign-in you made on yris.live; no separate sign-in in the extension
Personal communications	Chat messages you send (up to 200 characters) Chat reports: the reason you choose (abuse or dispute, spoilers, advertising, flooding, other) and any reason you type (up to 200 characters) Members you block, and your CleanChat setting Guide chatbot: questions you type (up to 500 characters) and the answers you receive	When you use chat, report, block, CleanChat, or the Guide chatbot
Website content	On Netflix pages only: the video number in the page address, the playback position, the video length, the playback status (playing, paused, seeking, buffering, ended), and whether an ad is showing whether certain Netflix controls are on screen (next episode, episode list, the next-episode countdown, “Watch Credits”, the ad label), found by Netflix’s internal element identifiers (`data-uia`) To read the exact position and to move the position, a script running inside the Netflix page uses the Netflix player’s own interface on that page. The extension does not read text shown on the page.	While a Netflix tab is linked to a Watch Together room, to keep playback in sync and to keep the room on its episode
Web history	The Netflix video number you are watching. It is sent only when you are the host, inside each playback report, so the server can check that you are on the room’s episode. The server compares it on arrival and does not store it.	Only while you are the host of a room
User activity	As the host: your playback actions (play, pause, seek, buffering, ad, episode change) and playback position, sent when they change and also at a regular interval set by the server (currently every 5 seconds) As the host: removing a participant from the room Joining a room Clicks and key presses on Netflix pages: checked inside your browser, only while a room is linked to the tab, to stop controls that would switch to another episode. They are not stored or sent. Guide chatbot: the episode the chatbot answers up to, and whether it came from the room’s episode, your progress, or your choice. To offer “up to where I watched”, the extension reads your YRIS reading history (the progress you declared and recently viewed titles) from `api.yris.live` and uses only the entry for the current title, inside the panel.	While you are in a room, or when you use the Guide chatbot
Location (IP address only)	The IP address and browser information (User-Agent) that reach our servers when the extension connects. No GPS or precise location.	Each time the extension connects to our servers

Data the extension does not collect

Your Netflix account, profiles, viewing history, cookies, or page storage
Text shown on web pages, including titles and subtitles
Data from any website other than Netflix pages and YRIS
Health, financial, or payment information, or precise location

The extension contains no analytics, advertising, or tracking code, and it does not load or run code from the network.

3. How we use the data

To sign you in to the extension with your YRIS sign-in, and to sign you out when you sign out on yris.live
To show rooms, participants, and chat, and to keep participants’ playback in sync with the host
To answer your Guide chatbot questions, let you continue earlier conversations, and apply usage limits
To prevent abuse: blocking chat flooding, handling chat reports, and applying blocks and CleanChat
To keep the service secure and to detect outages

Guide chatbot answers are generated by an external generative AI service (OpenAI, Section 4.b). Please do not type information that identifies you or others, such as names, contact details, or addresses, into the chatbot. We do not use your questions or conversations to train AI models.

We do not sell user data. We do not use or transfer it for advertising, for personalized ads, or to determine creditworthiness or for lending, and we do not use it for any purpose unrelated to the features in Section 1.

4. How we share the data, and with whom

User data from the extension is shared only with the parties below.

a. Other YRIS users

Participants in the same room see your member ID, nickname, and identification code, your chat messages, whether you are connected, and whether you are the host. If the host removes a participant, the room is told who was removed. When you are the host, your playback position and status are sent to the other participants’ extensions so their playback can follow yours.
Anyone, including people who are not signed in, can see the Watch Together room list on yris.live. For each listed room (public and password-protected) it shows the room title, room type, title and episode range, the episode now playing, the host’s member ID, nickname, and identification code, the number of viewers, and when the room was created.
Signed-in YRIS users can see the host, current episode, and playback position of any room in the room list, including password-protected rooms, before joining.
Your Guide chatbot conversations are not shown to other users.

b. Service providers that process data for us

Provider	What they do	Data they receive	Location
Amazon Web Services, Inc. / Amazon Web Services Korea LLC	Hosting our servers, databases, and logs	All data in Section 2 that reaches our servers	Stored in the AWS Asia Pacific (Seoul) Region; AWS operations and support may involve the United States
Datadog, Inc.	Performance monitoring and outage detection	Records of requests to our servers: the request address or route (which may contain a room number, a message number, or the member ID of a blocked member), method, result, timing, and User-Agent; for some servers, the IP address	United States (US5 region)
OpenAI OpCo, LLC	Generating Guide chatbot answers	Your question; earlier questions and answers in the same conversation and a summary of the conversation; the title name, episode titles, and character and term lists up to the answer’s episode; and the guide content used as sources. The same question is also checked for safety, and older parts of a conversation are sent to be summarized. No member ID, name, or email address is sent. Sent only when you ask the Guide chatbot a question.	United States
Langfuse GmbH or ClickHouse, Inc. (Langfuse Cloud)	Tracking errors in Guide chatbot answer processing	Title number, the episode the answer is based on, language, processing steps and outcome, and amount processed. No question or answer text, no member ID, and no conversation ID.	Japan (Tokyo region)

The extension does not send your data to Netflix, Google, or any company not listed above. On Netflix, it only opens the watch page for the room’s episode and controls the player inside the page: play, pause, moving the position, pausing just before an episode ends, starting a newly opened episode from the beginning, blocking controls that switch episodes, returning the tab to the room’s episode, and pressing “Watch Credits” when the next-episode countdown appears. It does not insert ads or other content into Netflix pages.

c. Legal requirements

We disclose data only when the law requires it (for example, a warrant from an investigative agency), or when it is clearly necessary to protect someone’s life, physical safety, or property. If the operator of YRIS changes, we will notify you before any data is transferred.

d. Access by the YRIS team

Team members look at this data directly only to investigate reported chats, to respond to security incidents, to comply with the law, or when you ask us to in an inquiry.

5. How long we keep the data

a. On our servers and with our providers

Data	Kept until
Chat messages	90 days after they are written
Chat reports and reported messages	6 months after the report is resolved, and at most 1 year after it is received. The reported message and the reason you typed are also written to service logs.
Room, participation, host-change, and removal records; block list; CleanChat setting	Until you delete your YRIS account. A block is deleted as soon as you remove it.
Playback sync state and connection status	The room ends (60 seconds with no one connected, or when the room’s episodes are finished)
The host’s Netflix video number in playback reports	Not stored
IP address and User-Agent received on connection	The connection ends (kept in server memory only). If a message is blocked as flooding, the member ID, room, and IP address are written to service logs.
Short-lived checks: chat flood counts, duplicate-send checks, nicknames cached for display	10 seconds, 3 minutes, and 1 hour
Sign-in: the `yris_rt` cookie, the access token, and the record of replaced sign-in tokens	The cookie lasts 14 days and is renewed each time it is used; the access token lasts 10 minutes; a replaced token’s record is kept only until that token would have expired
Guide chatbot questions, answers, conversation titles (the beginning of the first question), and conversation summaries	90 days after they are written
Guide chatbot usage counts and the temporary record kept while an answer is being generated	Up to 24 hours
Service operation logs	Up to 3 months
Datadog request records	Up to 30 days
Guide chatbot requests kept by OpenAI	Up to 30 days, under OpenAI’s API data policy (not used to train its models)
Langfuse processing records	90 days
Database backups	Up to 35 days, used only to recover from outages

When you delete your YRIS account, the data linked to your account is deleted within 5 days, and room records shared with other users are anonymized. Records with a fixed period above (such as chat messages) are deleted when that period ends. An access token issued to the extension before deletion may keep working for at most 10 minutes.

b. In your browser

chrome.storage.session, cleared when you close Chrome: the access token and its expiry, your sign-in status and member ID, which Netflix tab is linked to which room, and the last video number the extension returned a tab from.
chrome.storage.local, kept until you remove the extension: your panel language and theme.
Panel memory only, cleared when the panel closes: recent chat messages (up to 500), participants, your block list, and the Guide chatbot conversation. If a different account signs in, these are cleared at once.
When you sign out on yris.live, the access token is deleted and the connection to the Watch Together server is closed.

6. Security

All data between the extension and our servers travels over encrypted connections (HTTPS and secure WebSocket, TLS 1.2 or later).
The extension reads only one cookie, yris_rt, and never reads, changes, or sends other cookies. The access token is never given to scripts running in Netflix pages.
Only yris.live pages can send requests to the extension, and only three kinds: checking whether it is installed (the answer is “installed” and its version), opening a room (a room number and the Netflix address of its episode, which opens or focuses the Netflix tab and the panel), and checking for an update.
Our chatbot server filters its logs so that question text is not recorded.

7. Your choices and rights

Sign out on yris.live to sign out of the extension.
Remove the extension at any time from chrome://extensions. This deletes its browser storage.
Turn CleanChat on or off in the panel’s settings. Remove blocks on yris.live (Profile).
If you do not use the Guide chatbot, nothing is sent to OpenAI or Langfuse.
Delete your YRIS account on yris.live (Profile > Account settings > Delete account).
Ask to access, correct, or delete your data, or to stop processing it, by emailing yris.anime@gmail.com.

8. Children

YRIS accounts are only for people aged 14 or older. The extension works only with a YRIS account.

9. Chrome Web Store User Data Policy

The use of information received by this extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

10. Changes to this policy

If we change how the extension handles data, we will update this page and the date above, and announce the change in the full YRIS Privacy Policy.
