What2Wear Privacy Policy
Effective: August 2, 2026 · Last updated: August 2, 2026
What2Wear (“the App”, “we”) is a personal wardrobe and outfit app. This policy explains what we collect, why, where it is stored, and what control you have. Using the App means you accept this policy.
Where your data lives. Our servers and image storage are located in mainland China (Alibaba Cloud). If you use the App from outside China, your account data and any images you upload are transferred to and processed in China. We describe this in detail in Section 3 so you can make an informed choice before signing up.
1. What we collect
1.1 Information you provide
- Account: a phone number (mainland China numbers only) or, if you use Sign in with Apple, the anonymized identifier and relay email Apple gives us. We never receive your Apple password.
- Clothing photos you upload or capture.
- Outfit photos you explicitly choose to save as a record.
- Photos of yourself, only when you start an AI feature that needs one (AI model, virtual try-on, hairstyle, nail try-on).
- Outfit records: the combinations you build, dates worn, notes, and an optional location.
- Preferences: style, size, and body information you choose to enter.
1.2 Collected automatically
- Device data: model, iOS version, app version, language, time zone, and Apple's vendor identifier (IDFV).
- Location: only with your permission, and only for weather-based suggestions and optional outfit locations. Coordinates saved with an outfit are rounded to roughly 1 km before storage. We do not keep precise coordinates and do not build movement history. You can revoke this in iOS Settings at any time.
- Diagnostics: crash reports, error traces, and feature-usage events used to fix bugs and improve the App.
1.3 Photo scanning and face matching (off by default)
The App can help you find outfit photos already in your camera roll. This feature is off until you turn it on, and we ask for your consent separately before it runs. How it works:
- Everything happens on your iPhone. You provide a few selfies; the App derives a face template on-device and uses it to recognize which photos contain you.
- The face template never leaves your device. It is stored inside the app sandbox under iOS file protection. It is never uploaded, never used to train any model, and never shared with anyone. We do not store images of your face on our servers.
- Scanning reads photos locally for comparison. Photos do not leave your device because of scanning. Originals stored only in iCloud are not downloaded for this purpose.
- A photo is uploaded only when you tap “save this outfit” on it. Photos you dismiss are never uploaded.
- You can turn the feature off at any time under Profile → More Settings → Storage & Privacy. Turning it off deletes the on-device face template, the scan progress, and all pending candidates, and withdraws your consent.
- Granting access to only Selected Photos works fine.
1.4 What we do not collect
- Contacts, microphone, or health data.
- Payment details. The App offers in-app purchases (subscriptions and AI credits). All payments are handled by Apple. We never see or store your card number or payment credentials — we receive only a transaction receipt used to unlock what you bought.
- Passwords for any third-party account.
- We do not use your photos or face data for advertising, and we do not track you across apps.
2. How we use it
- Run the core product: wardrobe management, outfit suggestions, records, and statistics.
- Recognize clothing attributes (category, color, style) and cut items out of their background.
- Power the AI features you start yourself (AI model, try-on, hairstyle, nail try-on, product-image redraw).
- Suggest outfits based on local weather and what you actually own.
- Improve the product through aggregated, anonymized usage analysis.
- Send you account and security notices.
3. Storage, transfer, and security
- Location: account data and images are stored in mainland China on Alibaba Cloud. Images sit in a private, encrypted object-storage bucket reachable only through signed, expiring URLs.
- International transfer: if you use the App outside mainland China, the data described above is transferred to China for processing. China's data-protection regime differs from that of your home country and may afford different remedies. By creating an account you consent to this transfer. If you are not comfortable with it, do not create an account — and you may delete an existing one at any time (see Section 5).
- On-device only: face templates, scan progress, and pending photo candidates never leave your phone and are excluded from cloud backup.
- In transit: all traffic uses HTTPS/TLS.
- Access: least-privilege on the server side, with regular backups.
- Retention: we keep your data while your account exists. After you delete your account we erase it within 30 days. Intermediate images produced by AI jobs are purged on a recurring schedule.
4. Third parties
These providers process data on our behalf to deliver specific features. Each has its own privacy policy.
- Alibaba Cloud OSS — image storage.
- Alibaba Cloud Model Studio (Qwen / Wanx) — image recognition, cutout, and generation. Images are transmitted only for the duration of processing and are not used for model training.
- Volcano Engine Ark (Doubao Seedream) — image generation and redraw. Same terms: transient processing, no training.
- Alibaba Cloud SMS — login verification codes.
- Apple App Store / StoreKit — distribution and in-app purchases.
- Sentry — crash and error monitoring (never photo content).
- Weather data — coarse city-level location only; precise coordinates are never sent.
A shopping section powered by Chinese affiliate networks (Taobao / JD) is shown only to users whose App Store region is mainland China or whose device language is Chinese. It is not available otherwise.
5. Your rights
- Access and correct — edit your details under Profile → Personal Info.
- Export — email us for a copy of your data.
- Delete individual items — remove any garment, outfit, or AI result at any time.
- Turn off photo scanning — one switch under Profile → More Settings → Storage & Privacy deletes the on-device face template and every candidate.
- Delete your account — under Profile → Settings. This permanently erases your data.
- Withdraw permissions — revoke camera, photo, or location access in iOS Settings whenever you want.
To exercise any of these rights, or to complain about how we handled your data, contact us at the address in Section 9. We respond within 30 days.
6. Children
The App is not directed to children under 13 and we do not knowingly collect their personal information. If you believe a child provided us data without parental consent, contact us and we will delete it.
7. Cookies and tracking
The App is a native iOS app and uses no web cookies. We use Apple's IDFV for anonymous device identification. We do not use the IDFA and do not perform cross-app tracking, so the App does not present App Tracking Transparency prompts.
8. Changes
We may update this policy. Material changes will be announced in the App. Continued use after an update means you accept the revised policy.
