Privacy Policy
SHINSI Co., Ltd. ("SHINSI", "we") complies with the Personal Information Protection Act of Korea and other applicable laws. This policy explains what personal information we process, why, and how you can exercise your rights. The Korean version of this policy prevails in case of any inconsistency.
1. Purposes of processing
- Providing the service: connecting business calls (extensions and main numbers), incoming-call notifications, and the IVR, fax, recording and conference features under contract
- User verification: verifying users when they register the app (SMS verification code) and managing registered devices
- Customer support: handling inquiries and incidents, sending service notices
- Service integrity: preventing misuse, diagnosing failures and responding to security incidents
We do not use personal information for any other purpose and do not process it for advertising or marketing.
2. Information we process
| Category | Items | Source |
|---|---|---|
| User account | Name, extension number, mobile phone number, organization (company, department) | Registered in the portal by the business customer's administrator |
| App registration | Mobile phone number, verification records, device identifier (a random value generated by the app) | App registration |
| Call notifications | Push notification token (issued by Apple or Google) | Automatically when the app runs |
| Call records | Calling and called numbers, date, time and duration of calls, call result | Generated automatically when the service is used |
| If enabled by the business customer | Call recordings, fax documents, voicemail, conference participation records | Generated when the business customer turns on the feature |
| Access logs | IP address, access time, app version, operating system type | Generated automatically when the service is used |
| Inquiries | Name, company, email, phone number, message | When you contact us |
Call audio is relayed in real time to connect the call and is not stored unless the business customer has enabled call recording.
3. modu.PBX Phone app permissions
The app requests each permission when the related feature is first used. Optional permissions can be declined without affecting other features, and all permissions can be changed in your device settings.
| Permission | Type | Purpose |
|---|---|---|
| Microphone | Required | Phone calls |
| Notifications | Required | Incoming-call alerts (without them, you cannot receive calls while the app is closed) |
| Camera | Optional | Registering the app by scanning a QR code |
| Contacts | Optional | Importing your phone contacts into the app. Imported contacts are stored only on your device and never sent to our servers. |
| Bluetooth (Android) | Optional | Calls with Bluetooth headsets |
4. Retention
- User account and device information: until the business customer deletes the account or the service contract ends
- Call records, recordings, fax and voicemail: for the period set in the contract with the business customer (who can also delete them), and deleted when the contract ends
- Inquiry records: 3 years after resolution
Where Korean law requires retention, we keep the information for the required period, for example: communication confirmation data under the Protection of Communications Secrets Act (log records 3 months, other data 12 months); contract and payment records under the Electronic Commerce Act (5 years); records of complaints and disputes (3 years).
5. Disclosure to third parties
We do not provide personal information to third parties, except where required by law or requested by investigative authorities following legal procedures.
6. Service providers
We use the following service providers to operate the service and supervise them to keep personal information secure.

7. International transfers
To deliver incoming-call notifications, the following information is transferred outside Korea. You can turn off app notifications in your device settings, but you will then be unable to receive calls while the app is closed.
| Recipient | Country | Items | When and how | Retention |
|---|---|---|---|---|
| Google LLC | USA | Push token, notification content (caller number and display name) | Sent over the network for each incoming call | Per Google's policy after delivery |

All other service data, including call connection, call records, recordings and fax, is processed on our servers in the Republic of Korea.
8. Deletion
When the retention period ends or the purpose is fulfilled, we delete personal information without delay. Electronic files are deleted so that they cannot be recovered, and paper records are shredded or incinerated. Information we must keep by law is stored separately.
