MIEN Privacy Policy
MIEN is an app by Kioh, a software company in Vietnam, that helps you organize your wardrobe, get outfit suggestions, and shop smarter. This policy explains what data MIEN collects and how we protect it.
1. Information MIEN collects
We only collect what MIEN needs to suggest outfits and help you shop:
- Account & contact: your email and, if you sign up or contact us, your phone number, a display name, and an optional profile photo.
- Wardrobe content: photos of your clothing and item details (category, color, brand, notes) that you add. You choose whether each photo stays only on your device or is saved to the cloud.
- Body measurements & fit (optional): with your consent, measurements such as height, weight, chest/waist/hip and more detailed values, your body shape, and preferred fit. You can enter these yourself, or use the in-app body scan (see section 3). Used only to suggest better-fitting outfits and sizes.
- Color & style profile: your skin undertone, color season and palette, and the styles and colors you prefer — used to tailor outfit and color suggestions.
- Personal details (optional): your gender and date of birth, if you choose to provide them, to personalize suggestions.
- Location: with your permission, your device's approximate (low-accuracy) location and/or the city and country you set, used to suggest outfits suited to the weather and season.
- Outfit activity: the outfits you save and the suggestions you keep or dismiss, so recommendations fit you better over time.
- Basic technical data: limited information needed to run the app reliably, such as app version and device type. MIEN does not use third-party advertising or analytics trackers.
2. How we use your data
Your data powers the features you ask for: cataloging your wardrobe, generating outfit suggestions that fit your body and suit the weather, and recommending items that match your taste, size, and budget. We also use it to respond to you, keep your account secure, and improve MIEN. We do not sell your data and do not use it for third-party advertising.
3. Photos & AI features
MIEN offers an optional body scan: using your camera, it estimates your body measurements on your device with an on-device AI model. The scan images are processed on your device to produce measurements; only the resulting measurements are saved to your account, and only if you consent — the scan images themselves are not uploaded.
Other AI features send images to a trusted AI provider (Google Gemini) to process on secure servers: creating a clean image of each clothing item from your photos, generating a preview of you wearing an outfit (virtual try-on), and describing or suggesting outfits. Under our paid agreement with this provider, your images are not used to train its AI models. We never sell your photos, and do not use them for advertising.
4. Sharing
We do not sell personal data. We share only with trusted service providers — such as cloud hosting, AI processing (including Google Gemini), and subscription management (RevenueCat) — to the minimum extent needed to run MIEN, or where required by law.
5. Purchases & subscriptions
MIEN offers auto-renewing subscriptions through Apple's In-App Purchase system. Apple processes all payments — we never receive or store your card or payment details. We use RevenueCat to manage subscriptions: it processes a pseudonymous app user ID and your purchase and receipt status so the app knows whether your subscription is active. To enforce plan limits, we also record how many times you use AI features (such as item extraction and virtual try-on) each month.
6. Storage & security
Your account data and any photos you save to the cloud are stored on infrastructure with encryption in transit and at rest, and each user can only access their own data. You can choose to keep wardrobe photos only on your device instead of the cloud. We retain data only as long as needed for the stated purposes, then delete or anonymize it.
7. Your rights
You can view, edit, or delete any item in your wardrobe — as well as your measurements, fit profile, and personal details — at any time, and you can withdraw your consent to store measurements. To delete your account, go to Settings → Delete Account in the app: this immediately and permanently deletes your account, profile, measurements, wardrobe, saved outfits, and all photos you've stored with MIEN. You can also request deletion by emailing contact@kioh.tech. Deleting your account does not cancel an active subscription — subscriptions are billed by Apple and must be cancelled separately in your App Store subscription settings.
8. Children's privacy
MIEN is not directed to children under 13. We do not knowingly collect data from children.
9. Changes
We may update this policy as MIEN evolves. Material changes will be posted on this page with a new update date.
