Matjip Eodiya Privacy Policy

Effective: October 8, 2026 · 한국어

Matjip Eodiya in Korea (the "Service") is a free app that alerts you when you walk or drive near famous restaurants featured on Korean YouTube and TV, and lets you rate (⭕/❌), save and share restaurants you visit. This policy explains what information the Service uses and how it is handled.

Summary

No sign-up or login. We do not collect your name, phone number, email or any other identifying information.
Your location is used only on your device to measure distance to restaurants. It is never sent to our server.
The app collects location data to enable nearby restaurant alerts and visit detection (for rating) even when the app is closed or not in use. This is also processed only on your device.
Saved restaurants, alert history and visited places are stored only on your device.
When you rate a place, only the restaurant, your ⭕/❌, your reason and a random install ID (which doesn't identify you) are stored on our server. Reasons are visible to other users.
To keep the Service free, we show Google AdMob ads, which may use your advertising ID.

1. Information we process and why

Information	Purpose	Retention
Current location (latitude/longitude) — in use and in the background	Detecting when you are within 500 m of a famous restaurant to send an alert, showing your position and distances on the map, detecting stays of 10+ minutes within 100 m of a restaurant (a visit, which allows rating), estimating speed to tell walking and driving apart	Never sent to our server. Only the last checked position is kept on your device for speed estimation (no travel history)
Alert history, saved restaurants, visited places and visit times, app settings	Showing the Alerts and Saved tabs, checking rating eligibility, not alerting the same place again for 3 days	Stored only on your device and deleted when you uninstall the app
Ratings: restaurant, ⭕/❌, reason (optional, up to 200 characters), app language, random install ID	Counting ratings per restaurant and showing the "Special" badge (100+ ratings with 90%+ ⭕), allowing one rating per person per restaurant, showing reasons	Stored on our server (Google Firebase, Seoul region). The install ID is stored as an irreversible hash. Deleted when you delete your rating in the app. Only the latest 30 reasons per restaurant are shown
Reports: the reported review and the reporter's install ID (hashed)	Hiding abusive or spam reviews (hidden for everyone after reports from 3 different people)	Kept on the server with the reported review
Place reports: the restaurant, report type (closed, wrong location, wrong place, other), details (optional, up to 200 characters), install ID (hashed)	Checking and fixing wrong information in the restaurant list	Stored on our server (Google Firebase, Seoul region). May be deleted after we fix the listing. A new report from the same person for the same place replaces the old one
App error data: error details when the app crashes, device model, Android and app version, Firebase installation ID	Finding and fixing app errors (Google Firebase Crashlytics). No location or rating content is included	According to Google's policies (Crashlytics keeps crash records for 90 days)
IP address (hashed), install ID (hashed) and date	Preventing abuse by limiting how many ratings can be written per day	Automatically deleted after one day
Advertising ID (ADID), device and app information	Showing ads and measuring ad performance (Google AdMob)	According to Google's policies

2. Use of location data

Location is used only if you allow it. Precise location is required for the core feature (nearby restaurant alerts).
Background location: if you choose "Allow all the time", the app uses location data even when it is closed or not in use, to alert you near famous restaurants and to detect restaurants you visit. GPS is not kept on — the device's geofencing (Google Play services) wakes the app only when you come near a restaurant. Without "Allow all the time", alerts only arrive while the app is open.
Location data is processed only on your device and is never sent to our server or to third parties. Location fixes and geofencing on the device are handled by Google Play services.
When you tap "Directions", Naver Map or Kakao Map opens (app or web). If Kakao Map opens on the web, your starting position (current coordinates) is included.

3. Third parties and processors

Recipient	Information	Purpose
Google LLC (Firebase / Google Cloud, Seoul region)	Ratings and reports, hashed install ID, hashed IP address	Running the rating server, downloading the restaurant list
Google LLC (Google Play services / Google Maps)	Device location (processed on the device), map requests	Location, geofencing, maps
Google LLC (AdMob)	Advertising ID, device and app information	Ads
Google LLC (Firebase Crashlytics)	App error data, device model, OS and app version, Firebase installation ID	Analyzing app errors
Naver, Kakao, YouTube	Restaurant info in links you open (Kakao Map web directions include your starting coordinates)	Maps, directions, videos

We do not sell your information or share it with third parties for any other purpose. Google's handling of advertising data follows the Google advertising policies.

4. Notifications

We send notifications when you are near a famous restaurant, and once after you leave a restaurant you visited to ask for a rating (at most once per restaurant every 7 days). We never send ad notifications. You can turn off rating requests separately in the device's notification settings ("Rate places you visited").

5. Reviews (user content)

Rating reasons are shown to other users without your name. Please don't include personal information. Reasons containing links are rejected.
You can report abusive, spam or off-topic reviews. A reported review is hidden for you immediately and for everyone after several reports.

6. Opting out of personalized ads

In your device settings → Google → Ads (or Privacy → Ads) you can delete your advertising ID or turn off ad personalization. Users in the EEA and UK can change their consent in the app under Settings → "Ad privacy settings".

7. Your rights

You can turn off location and notification permissions at any time in device settings. (Without notifications and location, the core features can't work.)
You can edit or delete your rating at any time on the restaurant page; deleting it also removes it from our server.
Uninstalling the app deletes all data stored on your device. Ratings on our server are stored without information that identifies you, so please delete your ratings before uninstalling. For other requests, contact us below.

8. Children

The Service requires no sign-up and does not ask for age. We do not knowingly collect personal information from children under 14.
