Updated: 2026-09-18 · Effective: 2026-09-18
We understand how important your personal information is and will do our best to keep it secure.
This Privacy Policy explains how we collect, use, store, share, and protect your personal information when you use DayDayHair, and the rights you have.
Please read this policy carefully before using the app. By tapping agree, signing in, or continuing to use the service, you acknowledge that you have read and agreed to this policy.
1. Definitions and Scope
- Personal information means information recorded electronically or otherwise that relates to an identified or identifiable natural person, excluding anonymized information.
- Sensitive personal information means information that, if leaked or misused, could harm personal dignity or personal or property safety. In this app it mainly includes face/selfie images, precise location (for example when you use store navigation), and payment-related transaction identifiers.
- This policy applies to the DayDayHair client and related cloud services. Third-party services (such as WeChat, QQ, Apple, maps, and payments) have their own privacy policies, which you should also review.
2. How We Collect and Use Your Information
We collect only the information necessary to provide the product, in a lawful, fair, and necessary manner, as follows:
2.1 Account registration and sign-in
- Phone number / email, verification code, password, nickname, and avatar: used for registration, sign-in, account security, and profile display.
- Third-party sign-in: if you sign in with WeChat, QQ, or Apple, we receive the unique identifier (such as openid/unionid), nickname, and avatar that the platform provides within the scope you authorize, in order to create or link an account.
- Legal basis: necessary to perform the contract; your consent.
2.2 Hair analysis and virtual try-on (core features)
- Selfies or photos from your library: used to estimate facial features, recommend hairstyles and hair colors, and generate virtual try-on results. These images are sensitive personal information and are processed only after you take or choose a photo and confirm submission.
- Analysis report content: such as conclusions about face shape, hair volume, texture, length, and skin tone, recommended styles and colors, summary text, and try-on previews. Used to show results, history, and cloud sync within the scope you authorize.
- On-device processing: some capabilities (such as on-device hair segmentation and local try-on) may run on your device. Cloud analysis and AI try-on upload images to our servers and cooperating cloud services.
- Legal basis: necessary to perform the contract; your separate consent to process sensitive personal information (shown through the feature action and agreement checkbox).
2.3 History, favorites, and care calendar
- Analysis and try-on history, favorite preferences, and care reminders are used to show content across sessions. Some data stays on the device; some is synced to your cloud account.
2.4 Community and nearby stores
- Community content: text, images, likes, and comments you post, used for display, interaction, and safety review.
- Store information: browsing nearby stores may use approximate location or a city/address you choose. Calling and navigation open the system or a third-party map app.
- Merchant listings: if you submit a store name, address, phone number, hours, or store images, they are used for review and public display.
2.5 Payments and in-app purchases (if applicable)
- iOS per-analysis purchases and similar in-app purchases are processed by Apple. We only receive transaction receipts or order identifiers for verification and crediting. We do not collect your bank card number or payment password.

You can turn permissions off in system settings. Some features may then be unavailable, but basic browsing is not affected.
2.7 Support and feedback
- When you contact us in the app or by email, we collect the contact details, description, and necessary device or account information you provide, in order to handle inquiries and complaints.
3. Cookies and Similar Technologies
This app is mainly a native client and generally does not use browser cookies. We may use local storage (such as SharedPreferences) to keep your sign-in state, preferences, and local history so they remain the next time you open the app.
4. Processors, Sharing, Transfer, and Disclosure
4.1 Processors
- Object storage / CDN (such as Qiniu): stores selfies, try-on results, and community images you upload.
- Cloud AI / vision services: when providing cloud analysis or AI try-on, necessary images may be sent to cooperating providers. Intermediate results are deleted or anonymized as agreed after processing.

5. Storage and Protection
- Location: stored on servers in the People’s Republic of China in principle.
- Retention: kept only for the shortest period needed for the service. After account deletion or a deletion request, we delete or anonymize the data within a reasonable time, unless the law requires otherwise.
- Security: HTTPS in transit, access control, permission levels, and log auditing. No security measure is completely risk-free.
- If a personal information security incident occurs, we will notify you as required by law and report to regulators when necessary.

- Access and copy your profile, history, and favorites in “Me”.
- Correct and supplement your nickname, avatar, and similar profile details.
