1. Information We Collect

None. This app collects no personal information. There is no sign-up, no login, and no account of any kind. The app contains no advertising and no third-party analytics. The only thing sent to a server of ours is the anonymous usage events described below.

No advertising identifier (IDFA / GAID) is requested or used.
No third-party analytics, crash-reporting or attribution SDK is present in the app.
Anonymous usage events (Android app, from October 2026) — the app sends a small, fixed set of anonymous events (first launch, Pro notice shown, purchase started/succeeded/cancelled/failed, purchases restored, and whether the install is still alive on day 1 and day 7) to our server. Each event carries only a random install identifier generated by the app, the app tag, the event name and a timestamp — never an advertising ID, device identifier, name, saved numbers or location. We use them only to see where people drop off; raw events are kept for at most 90 days, after which only aggregate counts remain.
Nothing you record is sent anywhere. The app downloads public reference data (draw results, store list) from our own endpoint; those requests carry no personal information.
Location is used only while you are looking at nearby stores, and only on your device.

2. Where Your Data Lives

Data	Purpose	Stored
Draw results and store list downloaded from our endpoint	Showing results, statistics and the store map	Cached on your device

Anonymous usage events (random install identifier only, Android)	Finding drop-off points	Our server — raw for at most 90 days, aggregates afterwards

Location. The app asks for location only when you tap the "near me" feature, and uses it on your device to sort stores by distance. Your location is not sent to us and is not stored. You can decline, and every other feature keeps working.

3. Third-Party Services

The app contains no advertising or analytics SDK. The third-party components it does contain are Naver Maps iOS SDK. The external parties involved are Apple and the components below, and only for what you initiate:

In-app purchases — processed entirely by Apple through your Apple Account. We never see your payment details and receive no personal data from a purchase.
Naver Maps iOS SDK (NAVER Cloud Platform) — Drawing the store map. Governed by the NAVER Cloud Platform privacy policy.

Apple's handling of that data is governed by the Apple Privacy Policy.

4. Overseas Transfer of Personal Data

Not applicable. We do not collect personal data and therefore transfer none abroad.

5. Advertising and Tracking

No ads. The app displays no advertising of any kind.
No tracking. Nothing about you is tracked across apps or websites. The app does not present an App Tracking Transparency prompt.

6. Children

This app is for a general audience and is not primarily directed at children under 13. It collects no data from anyone, including children.

7. Your Rights
