Photo Dataset Usage Terms
Effective: 2026-01-01 · Last updated: 2026-05-13
These Terms govern the use of face photos and analysis data uploaded by Members for AI model performance improvement and research purposes. Explicit consent is required at sign-up.
Summary
• Uploaded photos may be used as training datasets to improve AI performance.
• All personal identifiers are removed (anonymized) before use.
• You may withdraw consent at any time.
1. Purpose
- Improve accuracy of AI pore/skin analysis models
- Develop new analysis metrics (e.g., zone-level, texture analysis)
- Statistical analysis of skin change patterns
- Correct model bias across race, age, gender for fairness
2. Data Used
| Type | Used? | Notes |
| Face photos (raw) | Yes | Model training input |
| AI analysis scores | Yes | Ground-truth comparison |
| Gender, age range | Yes | Bias correction (decade buckets only, no birth year) |
| Skin type | Yes | Model branching |
| Name, email, phone | No | Never included in training data |
| Location, device ID | No | Removed before training |
3. Anonymization
- Metadata removal: EXIF data (location, device, timestamp) fully deleted
- Identifier separation: User ID, email, name, phone removed; replaced with single-use anonymous IDs
- Hash conversion: Filenames converted to SHA-256 hashes
- Access control: Only authorized ML engineers; access logs retained 90 days
4. Retention
- Anonymized datasets retained for up to 5 years.
- Upon withdrawal of consent or membership, original photos mapped to personal info are deleted immediately.
- Already-anonymized data used in training cannot be technically reversed but will be excluded from future training.
5. No Third-Party Sales
The Company does not sell or transfer datasets to external entities, even if anonymized. Exceptions: non-profit research institutions with IRB approval (with separate Member notice), or legally mandated requests.
6. Withdrawal of Consent
You may withdraw consent at any time via:
- My Page → Settings → "Withdraw AI training data consent"
- Email: [email protected] (processed within 7 days)
Withdrawal does not affect service use; future uploads will not be used for training.
7. Member Rights
- Request to view which models your anonymized data was used in
- Request complete deletion from training datasets (within technical limits)
- Claim damages for harm caused by model outputs
8. Security
- Datasets stored encrypted in private Cloudflare R2 buckets
- 2FA and IP whitelist for access
- Quarterly external security audits
9. Amendments
Material changes are announced 30 days in advance. Members may re-consent or withdraw.
