Privacy Policy

1. Information we collect

We collect only what is necessary to provide the features:

• Account information: the email address you use to receive verification codes, the openid / unionid returned by WeChat sign-in, the user identifier returned by Sign in with Apple, along with the nickname you set, the user ID we assign and your registration time. We never receive your WeChat password or your Apple ID password.
• Content you enter: the name, category, price, purchase channel, purchase and sale dates and any follow-up expenses of your items and wishes; the name, notes and paid periods of your subscriptions; and the photos, order screenshots and the item images generated from them that you upload.
• Log data: our servers produce the access logs needed to run the service (such as IP address, request time and API path), used only for security and troubleshooting.

2. Information we do not collect

The app does not request location access, and does not read your contacts, text messages or list of installed apps. We have not integrated any third-party advertising or analytics SDK, we do not build user profiles, and we do not sell your information to anyone.

3. Device permissions

Both permissions are requested only when you start the corresponding action, and you can turn them off in your system settings at any time; doing so affects only the corresponding feature:

• Photo library: used when you pick an item photo or an order screenshot. On iOS you can grant access to “Selected Photos” only, in which case we can read just the photos you picked.
• Camera: used when you photograph an item or a receipt.

4. How we use this information

The information above is used only to provide the Service: to display and summarize your items and subscriptions; to read the screenshots you upload and fill in fields such as name, price and date; to cut the product out of the image onto a transparent background; to send sign-in verification codes; and to troubleshoot problems and prevent abuse. We use it for nothing else.

5. Third-party services and sharing

We do not sell or rent your personal information, and we do not use it for advertising. To provide the features above, the following third parties process the relevant information to the extent necessary; their own privacy terms also apply to what they do with it:

• Alibaba Cloud Object Storage (OSS): stores the images you upload and the item images generated from them.
• Alibaba Cloud Vision Intelligence Platform: cuts the product out of an image.
• Alibaba Cloud DirectMail: sends sign-in verification code emails.
• Large model platforms such as JD Cloud and Alibaba Cloud Bailian: receive the images you submit for recognition together with the necessary text prompts, and return the recognized result. We may change providers as recognition quality evolves.
• Serper (Google image search): when recognizing a subscription service, we search for an icon using the recognized service name — only the keyword is sent, never your screenshot.
• WeChat Open Platform and Apple: verify the corresponding third-party sign-in.

6. Disclosure required by law

We may have to provide information where laws or regulations require it, or where a judicial or administrative authority requests it through due legal process. To the extent permitted by law, we review such requests carefully.

7. Storage and protection

Your data is stored on servers and in Alibaba Cloud Object Storage located in mainland China, and is transmitted between the app and our servers over HTTPS. Unless the law requires otherwise, we keep this information until you delete it or delete your account. We take reasonable technical and organizational measures to protect it, but please understand that no method of transmission or storage on the internet is absolutely secure.

8. Your rights

Regarding your information, you can at any time:

• Access and correct: view and edit every record inside the app.
• Export: export all your items and wishes as an archive (images included) from “Me → Backup & Restore”.
• Delete: delete any single record directly.
• Delete your account: “Me → My Account → Delete Account” permanently deletes the items, subscriptions, recognition records, the account itself and the related image files. This cannot be undone, so export a backup first.
• Withdraw permissions: turn off photo library and camera access in your system settings.

9. Minors

This Service is not directed to children under 14. If you are a minor, please use it only after your guardian has read and agreed to this policy; guardians with questions about how a minor’s information is handled are welcome to contact us.

10. Updates to this policy

If we revise this policy, we will publish the new version on this page and update the date at the top; where a change is significant, we will also tell you prominently, for example with an in-app notice.

11. Contact us

If you have any question or complaint about this policy or about how your personal information is handled, reach us at “Me → Contact Support” in the app, or email yanwave@qq.com. We will reply as soon as we can.
