Privacy Policy
Inteliview (the "Company") operates the Bellin service (app and web, the "Service") and maintains this Privacy Policy under the Personal Information Protection Act of Korea to protect users' personal information and to handle related concerns promptly.
1. Purposes of processing
The Company processes personal information only for the following purposes and will take the necessary steps, such as obtaining prior consent, if a purpose changes.
- Account management: sign-in, linking your history when you change devices, responding to inquiries
- Providing the Service: voice calls with an AI partner, conversations tailored to you, post-call reports and review, call notifications at your scheduled time, generating conversation partner photos
- Paid services: verifying purchases and managing subscriptions (once paid services have started)
- Improving the Service: checking call quality and, only with your consent, improving recognition of Korean speakers' pronunciation
- Troubleshooting: identifying errors and improving app stability
2. Personal information we process
| Category | Items |
|---|---|
| When you start (all optional) | Name to call you, age range, what you do, language level, situations where you need the language, language you are learning, call partner settings, scheduled call days and time |
| When you create an account (required to make calls) | Email address (for Sign in with Apple, the email Apple provides) |
| When you make calls | Voice and conversation during the call (processed in real time), short notes to remember from calls, call summaries and reports, expressions to review, usage statistics such as call length and number of words spoken |
| When you use AI features | Depending on the feature: call audio and conversation; text for questions or translation; conversation for reports; name, age range, job, language level, goals, interests, review expressions and memory summary; partner descriptions and photo prompts; example text and selected voice |
| Only with your consent | Recordings of the parts of calls where you speak |
| When you use certain features | Settings and generated photos of conversation partners you create, device information for receiving notifications |
| When you use paid services | Product purchased, purchase and expiry information |
| When an app or web error occurs | Error name/message and part of the stack trace, app version/build, platform, screen/call status, fatal-error flag and authentication status (true/false) |
- Full conversation text is stored on your device. Relevant audio and conversation are sent to Google or OpenAI for live responses and post-call reports or memory extraction, and are processed in server memory while a report is generated. The Company does not persistently store full conversation text on its servers; saved call summaries, reports and memory notes are retained.
- Payment card details are handled by the app stores; the Company does not keep them.
- Error records do not retain account or device identifiers. Email addresses, long numbers and token-shaped strings in error text are masked before storage.
- Your conversation partner is an AI, not a person. You do not need to share confidential company information, real names or specific figures.
3. Processing and retention periods
The Company destroys personal information without delay once the purpose of processing has been achieved. Retention periods by item are as follows.
| Item | Retention period |
|---|---|
| User information, memory notes, review expressions, usage statistics, conversation partner settings and photos | Until you delete them or delete your account |
| Voice recordings you consented to | 12 months (deleted immediately if you withdraw consent) |
| Sign-in status | Up to 180 days |
| Device information for notifications | Until you turn off notifications, sign out or delete your account |
| Paid purchase records | Payment and refund records are kept by Apple and Google, which process the payments. We keep only the subscription status (product and period) and delete it without delay when you delete your account |
| Error records without account or device identifiers | Only the latest 500 records across the Service are retained; older records are automatically removed as new ones arrive |
4. Procedure and method of destruction
- When a retention period ends or you request deletion, the information is destroyed without delay. Account deletion takes effect immediately upon request.
- Electronic files are deleted in a way that cannot be recovered.
- Information that must be kept by law is stored separately from other information and only for the required period.
5. Provision to third parties
The Company does not sell your personal information or provide it for advertising or analytics. Processing by the service providers below to provide features, processing you consent to, and disclosures required by law are exceptions. Before an AI feature is first used, a separate screen identifies the data categories and Google Gemini or OpenAI and asks for consent before transfer.
6. Outsourcing of processing
The Company outsources the processing of personal information as follows to provide the Service.
| Processor | Outsourced task |
|---|---|
| Google LLC | Gemini voice calls, selected conversation partner photo generation, example-speech generation, app notifications (Firebase), Google sign-in (when selected) |
| OpenAI, L.L.C. | Selected OpenAI voice calls; hints, questions, translations, reports and memory extraction; safety checks of partner descriptions; selected conversation partner photo generation |
| Apple Inc. | Sign in with Apple, app notifications |
| Fly.io, Inc. | Server operation and data storage |
| Cloudflare, Inc. | Domain service, forwarding inquiry emails |
| Resend, Inc. | Sending sign-in emails |
| Apple App Store, Google Play | Verifying app purchases and managing subscriptions (once paid services have started) |
The Company's contracts require each processor to protect personal information at the same or a higher level than this policy promises, and not to use it for anything other than the outsourced task.
7. Transfer of personal information abroad
The Company transfers personal information abroad as follows to provide the Service. These transfers are outsourcing and storage necessary to perform our contract with you and are disclosed in this policy under Article 28-8(1)(3) of the Personal Information Protection Act.

Generated example audio is stored in Bellin's server cache |

- Transfers for each AI feature require consent before first use. If you decline, you cannot use AI calls, hints, questions, translations, reports, memory extraction, partner matching/photo generation or example speech. Voice-recording storage is a separate choice; declining it does not prevent other features. Deleting your account stops future transfers.
8. Your rights and how to exercise them
You may exercise the following rights at any time.
- Access: download the data the Company keeps about you in Settings.
- Correction: edit your user information in Settings. To correct your conversation memory, send a request to info@bellin.ai.
- Suspension of processing: you can ask info@bellin.ai to turn off the conversation memory feature. You can also withdraw consent to voice recording at any time; stored recordings are then deleted.
- Withdrawing consent to AI processing: calls only work by sending your voice and conversation to external AI services, so you cannot withdraw this consent and keep using calls. If you stop making calls, nothing more is sent. Deleting your account in Settings (Account management) withdraws the consent and deletes the data the Company keeps. If you cannot use the app, send a request to info@bellin.ai.
- Deletion: deleting your account or using "Delete my data" in Settings (Account management) immediately deletes all your data, including your conversation memory. To delete individual memories, send a request to info@bellin.ai.
If you cannot do this in Settings, you can send a request to info@bellin.ai and the Company will act without delay. You may also exercise these rights through a legal representative or an authorized agent.
The Service is only for people aged 14 or over. Under Korea's Personal Information Protection Act, processing the personal information of a child under 14 requires a legal guardian's consent; we do not accept users under 14, so we do not collect that consent. If we learn that personal information of someone under 14 has been collected, we delete it without delay.
9. Security measures
- Encryption of data in transit
- Minimizing access to personal information and controlling administrator access
- Sign-in without passwords (email link or code, Sign in with Apple)
- Minimizing stored information, for example by not storing full conversation text on our servers
10. Automatic collection devices and how to refuse them
The Company does not use cookies and does not use advertising or analytics tools. On the web, browser storage is used to keep you signed in and to save settings. You can delete it in your browser settings; doing so may reset your sign-in and settings.
