Privacy Policy
This English page is provided for convenience. The Korean privacy policy is the controlling version.
1. Purpose and Data Minimization
TaxZen, operated by JYFACTORY (Korean legal name: 제이와이팩토리리; representative: JOOYOUNG PARK; business registration no. 242-68-00754), avoids unnecessary personal data collection. The service can generally be used without account registration. Financial inputs needed for calculations, such as property prices, holding periods, and purchase or sale dates, are not intended to be permanently stored with personally identifying information.
2. Non-Identifying Analytics Data
Web analytics tools such as Google Analytics or Vercel Analytics may be used to understand traffic, usage frequency, and product usability. This may include anonymized IP information, cookies, visit timestamps, service usage logs, browser information, and device environment information.
3. Third-Party Provision and Processing
TaxZen does not provide user information to external parties in principle, except when required by law, processed into non-identifying statistics, or handled by hosting and infrastructure providers for normal web service operation.
4. User Rights
Because TaxZen does not generally collect account identifiers such as names, email addresses, or phone numbers for calculator use, there may be no personally identifying account data to correct or delete. Users may delete local browser data such as cookies through browser settings.
