Privacy Policy
Effective Date: May 6, 2026 · Last Updated: May 6, 2026
Geosan Tax Accounting Corporation (거산세무법인, hereinafter the "Company") values the personal information of its users and complies with the Personal Information Protection Act (PIPA) of the Republic of Korea and other applicable laws. This Privacy Policy explains how the Company collects, uses, retains, and disposes of personal information in connection with its tax refund services for foreign workers.
Article 1. Categories of Personal Information Collected and Methods of Collection
| Category | Items Collected | Method of Collection |
|---|---|---|
| Refund Inquiry & Application | Name, nationality, email address, year employment started, employment status, preferred language | Website application form |
| Tax Service Processing | Alien Registration Number | Collected directly by the partner tax accounting firm |
| Document Images (Required) | Photos of identification documents (Alien Registration Card / Passport), photos of the Withholding Tax Receipt for Earned Income (근로소득 원천징수영수증), Family Relation Certificate, and other document images required for tax refund processing | Captured with the device camera or selected from the photo library within the mobile app by the user |
| Web — Automatically Collected | IP address, browser information, visit timestamp | Server logs |
| Mobile App — Automatically Collected | Device information (operating system type and version, app version, device model); Authentication tokens (JWT Access Token / Refresh Token — stored in iOS Keychain or Android Keystore, transmitted only as an authorization header on API requests); Crash and error logs (anonymous diagnostic data containing no personally identifiable information) | Automatically when the mobile app is launched |
Article 2. Mobile App Permissions (iOS / Android)
Our mobile app requests the following device permissions. You may revoke any permission at any time through your device's operating system settings; doing so may, however, limit access to the related features.
| Permission | Purpose | Data Flow |
|---|---|---|
| Camera | To capture tax-related documents — such as your identification, Alien Registration Card, and Withholding Tax Receipt — for upload. | Captured images are transmitted to our servers (AWS) only at the moment you tap the "Submit / Upload" button. |
| Photo Library | To upload tax-related document images you already have on your device. | The app accesses only the images you explicitly select; it does not scan your entire photo library. |
| On-device Text Recognition (OCR) | To automatically extract information from captured documents using the operating system's built-in text recognition (Google ML Kit / Apple Vision). | Recognition runs entirely on your device. The original images are not transmitted to any external service for OCR. |
Article 3. Purpose of Collection and Use
- To assess eligibility for a tax refund and provide rectification claim (경정청구) services
- To confirm service applications and notify users of the results (via email)
- To delegate work to Geosan Tax Accounting Corporation
- To comply with obligations imposed by applicable laws
- To improve service quality and conduct statistical analysis (in de-identified form)
Article 4. Retention and Use Period
As a general rule, personal information is destroyed without delay once the purpose of collection has been achieved. However, the following items are retained for the periods required by applicable laws.
| Legal Basis | Item Retained | Retention Period |
|---|---|---|
| Act on the Consumer Protection in Electronic Commerce | Records of contracts and withdrawal of subscription | 5 years |
| Framework Act on National Taxes | Tax-related documents | 5 years |
| Protection of Communications Secrets Act | Service access logs | 3 months |
Article 5. Provision of Personal Information to Third Parties
As a general rule, the Company does not provide users' personal information to third parties. Exceptions are limited to the following cases:
- When the user has given prior consent
- When required by applicable laws or requested by competent authorities such as the National Tax Service
Article 6. Outsourcing of Personal Information Processing
| Processor | Outsourced Work |
|---|---|
| Geosan Tax Accounting Corporation (거산세무법인) | Filing of rectification claims and tax processing |
| Amazon Web Services (AWS) | Server infrastructure operation and data storage (Region: Seoul, ap-northeast-2) |
| Apple Inc. / Google LLC | Mobile app distribution platforms and push notification delivery |
Note: Text recognition by Google ML Kit and Apple Vision is performed entirely on the user's device (on-device processing) and therefore does not constitute outsourcing of personal data.
Article 7. Users' Rights and How to Exercise Them
Users may exercise the following rights at any time:
- Request access to, correction of, or deletion of personal information
- Request suspension of the processing of personal information
- Request portability or transfer of personal information
Requests may be submitted by email to the Privacy Officer listed below and will be processed within 10 days.
Article 8. Destruction of Personal Information
Personal information whose retention period has expired or whose purpose of collection has been fulfilled is destroyed without delay. Electronic files are permanently deleted in a manner that prevents recovery, and printed materials are shredded or incinerated.
Article 9. Privacy Officer
For reports or consultations regarding personal information infringement, you may also contact the Personal Information Protection Commission (privacy.go.kr) or the Korea Internet & Security Agency (118.go.kr).
