Good Health Technology Co., Ltd. (美好健康科技股份有限公司, "we", brand name iFRESH, website www.twifresh.com) takes the protection of your personal data seriously. This policy follows Taiwan's Personal Data Protection Act ("PDPA") and explains how we collect, process and use your personal data and what rights you have. By registering as a member, signing in with LINE, or using our skin analysis and skincare services, you confirm that you have read, understood and agree to this policy.

1. Data controller
Good Health Technology Co., Ltd. Address: 8F-1, No. 123, Sec. 2, Chongqing N. Rd., Datong Dist., Taipei 103, Taiwan. Email: ifresh@goodhealthtw.com
2. Purposes of collection
We collect your personal data for the following purposes:
To provide skin analysis and skincare reference information compared against population norms (not a medical diagnosis).
Member management, identity verification and sign-in (including LINE Login).
Personalised skincare suggestions and product or service recommendations based on information such as your age and sex.
Customer service, contact, notifications and after-sales service.
Legal compliance and internal management necessary for our operations.
Checking eligibility for and redeeming promotional gifts linked to skin tests.
Measuring clicks and purchases from product recommendation links (referral attribution) to calculate partner performance.
Statistical analysis and academic research using de-identified data (for example, research on skin condition and environmental exposure). Research results never identify individuals.
Note: our skin analysis is cosmetic reference information. It is not a medical service and must not be used to diagnose or treat any disease.
3. Categories of personal data
Identification and contact data: name, mobile number, email.
Characteristics: date of birth (to calculate age) and sex.
Images: facial photos taken for skin analysis.
Third-party sign-in data: when you use LINE Login, the user ID, display name and (with your consent) email address provided by LINE.
Location: with your permission on your device, your location (latitude and longitude) at the time of a skin test, used to look up air quality, UV, temperature and humidity at that moment and stored with that test record. You can decline; the test still works.
Questionnaire data: skin health survey answers you choose to give (for example daily routine, sun care and skincare habits, exercise, recent aesthetic treatments).
Service usage records: test times, report views, and clicks on recommended product links.
4. Period, area, recipients and method of use
Period: from the date of your consent until you end your membership or ask for deletion, or until the purpose of collection ends or any legal retention period expires. Facial images are used only for skin analysis and are deleted automatically once the analysis is complete; only the analysis values are kept. If you choose to keep a photo for before-and-after comparison, it is stored for 180 days and then deleted automatically. You can also delete it at any time from your test report page.
Area: where we operate, and where our cloud service providers operate. AI analysis of facial images uses Google Cloud services in the Tokyo, Japan region.
Recipients: us and the partners or processors needed to provide the services above (for example cloud hosting and IT service providers). We do not sell your personal data or share it for unrelated purposes. To redeem a skin-test gift, we give your name and mobile number to our partner retail counters, only so they can verify you and hand over the gift. When you click a recommendation link and buy on a partner brand's website, the partner may send us the order number, amount and the buyer's mobile number or email so we can match and measure results. We never share your skin test data or facial images with partner brands; they receive only de-identified or aggregated performance data.
Method: automated or non-automated processing, limited to what the purposes require.
5. LINE Login
When you sign in with LINE, LINE's third-party authentication verifies your identity. We receive only the identifiers needed to sign you in. Your LINE account and password stay with LINE and are not available to us. For LINE's privacy practices, please see LINE's privacy policy.
6. Data security
We use appropriate technical and organisational measures, including encrypted transmission, access control and secure storage, to protect your personal data against unauthorised access, alteration or disclosure.
7. Your rights
Under Article 3 of the PDPA, you may exercise the following rights over the personal data we hold:
To ask about or review your data.
To request a copy.
To request additions or corrections.
To request that we stop collecting, processing or using it.
To request deletion.
You can check and update your details in My Account, or email ifresh@goodhealthtw.com to exercise these rights. We will respond within a reasonable time.
8. If you do not provide personal data
The data above is needed to provide skin tests and member services. If you do not provide it or ask us to delete it, we cannot provide the full test and skin health services, but you can still browse the public content of this website.
9. Changes to this policy
We may update this policy as our business or the law changes. Updates are posted on this website without separate notice.
10. Minors: if you are under 18, you may use the service only after your legal guardian has read, understood and agreed to this policy.
Consent: I have read and understood the above, and I agree that Good Health Technology Co., Ltd. may collect, process and use my personal data (including facial images) for the purposes and within the scope described above.
