Privacy Policy

Summary

• The app does not require an account.
• The app does not use third-party advertising, analytics, or tracking SDKs.
• The app does not request your name, email address, phone number, contacts, photos, or precise location.
• Saved items, basket items, filters, hidden items, cached market data, and app settings are stored on your device.
• If you choose to submit bought-price feedback, the app sends the purchase details described below.

Information Stored On Your Device

The app stores local data needed to run the shopping experience, such as saved crops, basket contents, hidden items, display settings, downloaded market data, pending bought-price submissions, and a random contributor ID. This local data is stored by iOS app storage APIs such as SwiftData and UserDefaults.

Market Data Downloads

The app downloads public market-data files so it can show current estimates and historical context. These downloads are used to deliver app content and do not require you to identify yourself.

Optional Bought-Price Feedback

When you mark a basket item as bought and submit what you paid, the app sends a feedback record to improve future price calibration. The current submission includes:

• a random client submission ID,
• a random contributor ID stored on your device,
• the produce item ID,
• the bought date,
• the total paid in New Taiwan dollars,
• the quantity and unit,
• the calculated NT$/斤 value,
• the app version, schema version, and server receipt time.

The bought-price feedback does not include your name, email address, phone number, account login, precise location, photo library, contacts, or advertising identifier.

How Information Is Used

Local app data is used to remember your app preferences and shopping state. Optional bought-price feedback is used to calibrate and audit market price estimates, including filtering out unreliable contributor patterns when needed.

Sharing

Bought-price submissions are processed by the app's backend service. Public market-data hosting and bought-price processing currently use Cloudflare infrastructure. This website is hosted by GitHub Pages. The app does not sell personal information.

Retention And Deletion

Data stored on your device can be removed by deleting the app. Bought-price feedback may be retained to improve price estimates and protect the quality of the dataset. You can contact support to ask about a submitted feedback record, but locating a specific record may require enough details to identify it.

Children

The app is not directed to children under 13, and it does not knowingly collect personal information from children.

Changes

This policy may be updated as the app changes. The date at the top of this page shows when the current version was published.
