Privacy Policy
Daywink is designed to work without an account. Most personal content stays on your device, and we do not sell personal data or use it for cross-app tracking.
Who is responsible
Qilong Liu, operating as Daywink ("Daywink", "we", "us"), provides the Daywink app and website and is responsible for the processing described in this policy. Privacy questions and deletion requests can be sent to support@daywink.app.
Information stored on your device
The app may store your chosen display name, birth details, MBTI answers, diary entries, saved readings, wardrobe photos and app preferences on your device. This content is not routinely uploaded to us. You can reset individual areas in the app, clear the wardrobe, or remove all local data by deleting the app. The data export and restore tools let you move a copy yourself.
Optional Daywink account
You can use Daywink, purchase a subscription or Wink credit pack, restore eligible purchases, and use paid features without creating a Daywink account. Sign in with Apple is optional. If you choose to sign in, we receive Apple's stable account identifier and may receive the name and email address Apple shares on first authorization. We use this information to operate your optional account and associate eligible account records. Apple processes purchases separately through your App Store account. We verify Apple's signed transactions and device proof to maintain a purchase wallet and restore eligible entitlements and the remaining purchased Wink-credit balance on supported devices, without requiring your name or email.
You can sign out or initiate permanent account deletion in the app. Deletion removes the account's Apple sign-in identifier, name, email, account/device associations and account sessions from our active systems. It does not automatically delete the profile, diary, saved readings or wardrobe files stored locally on your device; remove these using the app's local-data controls or by deleting the app. Purchase wallets remain separate from optional account records: eligible App Store subscriptions and unused purchased credits remain recoverable through Restore Purchases without signing in to Daywink. Account-only promotional credits are removed on account deletion; purchase-backed subscription allowances remain subject to their subscription cycle. Older account-linked purchases are recovered from verified transactions and their remaining balances, not by granting the original purchase again. The 275 Wink-credit pack is a consumable; each purchase is a user-initiated one-time purchase, never renews or charges automatically, and purchased credits do not expire. We retain the pseudonymous purchase identifiers, wallet records and limited transaction history needed for restoration, refunds, duplicate-delivery prevention, accounting, disputes and legal compliance. These purchase records do not require your name or email. Deleting a Daywink account does not cancel an Apple subscription.
Information used by online features
- AI requests: Daywink does not include or download an on-device language model. Model-generated responses use a cloud AI service only after you deliberately start and confirm the relevant feature. Generated text conversation costs 3 Wink credits, a conversation request containing an image costs 5 Wink credits, and a styling or complete master report costs 30 Wink credits. The app shows the applicable price before sending a paid request; Wink credits are deducted only after a successful response, and a failed request releases the hold. Sent information may include the text you submit, relevant result or profile context, language, feature name, or a photo you deliberately attach to a conversation. We do not write ordinary AI conversation text or submitted images to our operational database. The cloud AI provider may process them to provide, secure and troubleshoot the response under its applicable terms.
- Color wheel: members can complete unlimited spins without spending Wink credits, whether started by a hand gesture or by tapping. Nonmembers spend 1 Wink credit per completed spin. The first-use notice explains the cost before you agree; opening the camera, an empty wheel or cancelling before completion does not spend credits. Front-camera frames and hand landmarks are processed on device, never saved or uploaded. Only the selected result and necessary billing identifiers go to our server to settle the credit and recover an interrupted delivery without charging twice.
- AI content reports: if you deliberately report an AI answer, the reported question, answer and note are sent to us and stored so we can investigate that report. They may include personal information you included in the question or answer. This reporting is separate from optional product analytics and occurs only when you choose to submit the report. The current release does not offer reading-accuracy votes or a personal accuracy-history feature.
- Earlier stock-reading features: the current release does not expose a dedicated stock or live wealth-reading tool. Financial questions you type in Wink AI are handled as ordinary AI conversation under the disclosure above and do not automatically start a dedicated stock lookup. Earlier app versions may still send a stock name or ticker to the separate stock-reading service. For those requests, a normalized search term and resolved security identity are retained in a shared lookup cache to identify the same security consistently and avoid repeated provider lookups; date-specific reading data is cached for up to seven days. These records are used to provide and maintain that service, not for advertising or cross-app tracking.
- Outfit temperature: the current release does not request or transmit your device location and does not contact a weather service. Outfit advice uses an on-device seasonal temperature estimate based on the region you select and the current month.
- Essential service operation: a random installation identifier is used for device authorization, quotas, purchases, account/device linking, configuration delivery, fraud and abuse prevention. We may also process app language/region and app version needed to deliver the service. Cloud and quota requests create technical records such as feature/API path, request timing, outcome, provider/model and configuration version. App launches, check-ins and reward actions may also be recorded when needed to operate those features. These performance, diagnostic and essential interaction records are linked to the installation and may be linked to a Daywink account after sign-in. They do not contain ordinary AI conversation text or submitted images.
- Optional product analytics: this is off by default. If you expressly enable it during onboarding or in Settings, we may receive product-interaction steps (for example onboarding, first use of a feature or paywall view) and app/OS context. These optional records do not contain your questions, AI answers, diary entries or photos. We use these first-party records to understand feature use and improve Daywink. Turning the setting off stops future optional analytics without disabling auth, quotas, purchases, configuration, cloud requests or any other app feature. This information is not used for advertising or cross-app tracking.
- Purchases and notifications: Apple processes payments. We may receive transaction and subscription status from Apple to provide paid features, prevent duplicate delivery, restore eligible access and evaluate aggregate subscription and revenue performance. If you enable notifications, an Apple Push Notification service token and language are stored for service and reminder notifications. At launch, Daywink does not use account, purchase or activity data to send segmented promotional notifications.
Photos
Wardrobe photo capture and tagging run on your device. If you explicitly select garments for a cloud styling plan and approve its confirmation, only their selected category, color and material descriptions are sent with your stated occasion and preferences; wardrobe photos, prices and wear history are not sent for that plan. A chat photo is sent only after you attach it and approve that cloud request. Daywink does not use these images for advertising or cross-app tracking.
Optional color-game gestures: the camera is activated only when you choose the hand-gesture option and grant camera permission. Frames are processed on your device to detect hand movements. They are not saved, uploaded, used to identify you or analyzed for palm-reading predictions. Capture stops when you leave the feature or the app moves to the background. You can use the full color game with its on-screen button without camera permission.
Service providers and international processing
We use service providers to host the API, generate cloud AI responses, and process accounts, purchases and notifications. These include Tencent Cloud (API hosting), Volcengine Ark, BytePlus ModelArk and OpenAI (cloud AI), and Apple (Sign in with Apple, app distribution, payments and push notifications). The provider used for a particular cloud AI request can depend on its feature, language and service availability. The app does not bundle or download an on-device language model. Cloud requests may be processed outside your country. We share only what is reasonably needed for the requested service, and providers process it under their applicable terms, agreements and privacy or security commitments. We require service providers that receive personal data to provide the same or equivalent protection described in this policy and required by applicable law.
Retention
Local interrupted-request recovery: while a paid styling, chat or letter request is unfinished, its original inputs, chosen language and operation identifier may be kept in protected app storage on your device, excluded from routine backups. This can include a photo deliberately attached to that unfinished chat request. Keeping the original request allows you to recover the same operation instead of paying for a new one after changing settings. The temporary request copy is removed after its answer has been saved and accepted; ordinary conversation or wardrobe records remain under their normal local-storage controls.
Paid-answer recovery: to recover an answer after a connection interruption without charging twice, we temporarily retain the generated result for up to 24 hours in a separate recovery cache, excluded from routine operational database backups. The result is available only to the same authorized account or installation that requested it. The recovery cache does not store the original request, prompt or submitted image; the generated answer itself may refer to information you provided. Account deletion removes its recoverable results. Results may become unavailable earlier if the cache is lost, but the durable billing record prevents the same operation from being charged again. Minimal operation identifiers, fingerprints and settlement records are retained for duplicate-charge prevention and accounting; they do not contain the generated answer.
Ordinary AI prompts and images are not written to our operational database. Records from earlier stock-reading features may remain in the shared lookup cache until they are refreshed or no longer needed; date-specific stock reading data is cached for up to seven days. Withdrawing the dedicated feature from the current app does not immediately erase records from earlier versions or requests. Essential technical records, optional analytics you enabled, purchase records and user-submitted AI content reports are retained only as long as reasonably needed to operate, secure and improve the service, resolve disputes, or meet legal obligations. Backups expire on a rolling schedule. We may retain aggregated statistics that no longer identify an installation.
Your choices and rights
The current release does not request device location. You can decline notifications, optional account creation, optional product analytics and individual cloud AI requests without losing deterministic, non-AI features. The product-analytics setting is available at any time in Daywink Settings; turning it off stops future optional sharing. You can delete local content with the controls in the app, initiate deletion of a Daywink account in the app, and manage Apple purchases in your Apple account. Depending on where you live, you may have rights to access, correct, delete, restrict or object to processing. Contact support@daywink.app; we may need limited information to locate the record and verify the request.
Children
Daywink is not directed to children under 13, or the higher minimum age required in their country. We do not knowingly collect personal information from children.
Security and changes
We use HTTPS, access controls and operational safeguards, but no system is completely secure. We will post material policy changes here and update the effective date. If a change requires consent, we will request it in the app.
