Privacy Policy
This English version is a translation for convenience. If it differs from the Korean version, the Korean version prevails.
Hairgraphy (the "Operator") processes the personal information of people who use the Ruen service (the app and this website) as follows. This policy covers the features provided during the closed beta.
1. What we process, why, and for how long
| Area | Items | Purpose | Retention |
|---|---|---|---|
| Your PC (app) | Your messages, generated replies, long-term memory, nickname and relationship settings, to-dos, notes and reminders, service settings, adult check result, consent records, error records | Keeping conversation history and using it in later conversations; detecting crisis expressions on the device and showing where to get help | Until you delete it or withdraw a required consent. After deleting individual items, copies may remain in automatic backups on your PC for up to 35 days. |
| Chatting with Nia (Ruen server, Ruen Plus) | Recent and past conversation needed for this message and reply, selected long-term memories, nickname and relationship settings, time and time zone, game and video watch-along context, beta access information (pseudonymous participant number, installation identifier) | Generating AI replies, checking access, managing usage limits and costs, preventing abuse | The Operator's server does not store conversation text. Usage records are kept until 7 days after the period ends, settlement records up to 30 days, and access information until the permit expires. |
| Reaction judgement | Your recent message (up to 1,200 characters) and the recent reply (up to 800 characters), the character's reaction criteria, game advice and reply-check sentences during watch-along, beta access information | Choosing Nia's expressions and gestures, game advice and reply checks | The Operator's server does not store the text. Daily counts are kept for 7 days and monthly counts until the 7th of the following month. |
| Chatting with Nia (your own ChatGPT) | The same items as chatting with Nia, plus to-dos, notes and reminders used for the reply | Generating replies with the ChatGPT account you connected | Does not pass through the Operator's server. OpenAI's terms and your account settings apply. |
| Beta code | Beta code (stored only as a hashed value), pseudonymous participant number, installation public key and its hash, registration and release times | Checking beta eligibility, preventing misuse | 30 days after the beta ends |
| App updates | App version, IP address | Checking for and downloading new versions | Not stored on the Operator's server |
| Sending feedback | Your feedback (up to 2,000 characters, with contact details and addresses masked), app version and language, and, if you choose, diagnostics (operating system, hardware ranges, fixed-code error records) | Checking errors, improving the service, responding to safety issues | 30 days after the beta ends |
| Usage statistics and surveys (optional) | Random installation number, app version, fixed usage events with counts and ranges, survey answers (scores and choices). No conversation content or free text is collected. | Measuring and improving service quality | Events 21 days, control records 30 days, surveys 29 days from receipt (the exit survey until 30 days after the beta ends) |
| Beta application and operation | Email address, application content, participant alias, adult check method and date | Selecting, informing and running the beta | 30 days after the beta ends |
| Payment | Name, mobile number, email, payment method information, payment and cancellation records | In-app subscription payment, refunds, keeping transaction records | Payment method information is processed by the payment provider. Transaction records are kept for the period required by law (payment records: 5 years). |
| Inquiries and rights requests | Email address and phone number, request content | Handling inquiries, complaints and privacy requests | 1 year after the request is resolved |
Records that a crisis notice was shown (a random number, date and country; no conversation content) are kept on your PC for up to 2 years to prepare legally required reports. Game watch-along analyses the game window only on this PC; screen images are not stored or sent off the PC.
2. Sensitive information
Conversations may contain sensitive information such as physical or mental health. With your separate consent, the Operator processes it only to generate replies, keep long-term memory, judge reactions and detect crises on the device. Long-term memory is a required feature of the Service. If you refuse or withdraw this consent, you cannot use the app.
3. Processors and transfers abroad
The Operator entrusts processing to the companies below to provide the Service, and personal information is transferred abroad in the process. Each transfer happens over an encrypted connection (HTTPS) whenever you use the feature. AI providers are asked not to use inputs for training and not to retain them (training opt-out and zero retention).
| Recipient (country, contact) | Items | Purpose | Retention |
|---|---|---|---|
| Cloudflare, Inc. (United States, [email protected]) | Items processed on the Operator's server in table 1, IP address | Running the Operator's server (relaying chat and reaction judgement, beta codes, updates, feedback, usage statistics) and this website | As in table 1 |
| OpenRouter, Inc. (United States, [email protected]) | Chatting with Nia, reaction judgement items | Relaying AI reply generation and reaction judgement | Zero retention. Billing, security and legal records follow the provider's policy. |
| Microsoft Corporation (United States, +1 425 882 8080) | Chatting with Nia items | Generating AI replies (Azure) | Zero retention. Legal records follow the provider's policy. |
| TypeSafe AI, Inc. (United States, [email protected]) | Reaction judgement items | Reaction judgement | Zero retention. Legal records follow the provider's policy. |
| OpenAI OpCo, LLC (United States, [email protected]), when you chat through your own ChatGPT | Your own ChatGPT items | Generating replies with your account | OpenAI's terms and your account settings |
| PortOne · KG Inicis (Republic of Korea) | Payment items | Processing payments | As required by law and the payment provider's policy |
To refuse a transfer abroad, decline it on the consent screen or withdraw consent in Settings. If you refuse or withdraw a required item, you cannot use the app. You choose the chat route (Ruen server or your own ChatGPT), and nothing is sent through a route you did not choose. Usage statistics are optional; refusing them does not affect other features. Information already sent cannot be recalled by deleting it on your PC.
4. Destruction
When the retention period ends or the purpose is achieved, information is destroyed without delay. Electronic files are deleted so that they cannot be restored. You can delete records on your PC yourself with the app's deletion function, and when you withdraw a required consent, the app destroys Ruen data and automatic backups on this PC. Records that must be kept by law are kept separately for that period and then destroyed.
5. Your rights
You can request access to, correction, deletion or suspension of processing of your personal information, and withdraw consent. For information stored on your PC, you can do this yourself in the app's Settings (consent management, data deletion). For information held by the Operator, contact [email protected] or +82-10-9203-0278.
6. Security measures
Encryption in transit, no storage of conversation text on the Operator's server, encrypted storage of connection information, and minimal access to the Operator's server and stored information.
7. Cookies and similar technologies
The Ruen app and this website do not set or use cookies. This website's access records (IP address, access time and similar) are processed by the hosting provider (Cloudflare) under its own policy.
8. Under 19
The Service is only for people aged 19 or older, and the Operator does not knowingly collect personal information of anyone under 19.
