Privacy Policy
Effective 4 November 2026
This policy explains what information the Wantok Market app collects, why it is used, who can see it, and how it is deleted. Wantok Market is operated by Hyunki Kang ("we", "us"). Contact: kanghhkk@gmail.com.
1. Information we collect
- Google sign-in: When you sign in with Google, Google gives us your email address, name and profile photo address. We use your email address and Google account ID to identify your account. Your Google name and photo are not shown in the app.
- Profile: the nickname you choose, your neighbourhood and your Wantok Meter.
- Listings: title, description, category, price, whether you accept offers, photos, meeting place, neighbourhood, status (selling, reserved, sold or hidden) and when the listing was posted or changed.
- Chats: messages you send and receive, when they were sent, and whether they were read.
- Activity: listings you save, users you block, and reports you send (the reason and the listing or user reported).
- Technical logs: IP address, time, and device or browser details when the app connects to our servers. Used for security and for fixing errors.
- On your device only: language, display mode, visible area and recent searches. These are not sent to our servers.
- Ads: The app shows ads from Google AdMob. Google collects your device's advertising ID, IP address, device and app information, and how you interact with ads, to show, measure and personalise ads. We do not send your account, listings or chats to advertisers.
The app opens your photo library only when you pick photos for a listing, and uploads only the photos you pick. The app does not use your camera, contacts or GPS location. You choose your neighbourhood yourself.
2. Who can see your information
- Anyone using the app, even without signing in, can see your nickname, your Wantok Meter, and your listings with their photos, price, category, neighbourhood, meeting place, status, posting time and number of saves. Listing photos are stored at public web addresses.
- Only the two people in a chat can read its messages.
- Blocks and reports are not shown to the person you block or report.
- We access stored information only when needed to run the service, handle reports or answer your requests.
We do not sell your information. The app shows ads from Google AdMob (see section 4).
3. How we use information
- To sign you in and keep your account
- To show listings by place, category and search
- To deliver chats between buyers and sellers
- To keep the market safe: handling reports and blocks, and hiding a listing automatically after several users report it
- To answer your questions and requests
- To show ads through Google AdMob, which keeps the app free
