SumDash

Privacy Policy

Effective: June 28, 2026

YT Lab ("we") operates the mobile game SumDash ("the app") and respects your privacy. This policy explains what information the app processes and how. The app has no sign-up or login and does not collect your name, email, phone number, contacts, or precise location.

1. Information We Process

Item	When	Purpose
Nickname (a 3-letter tag you enter)	When submitting a score to the global ranking	Shown on the leaderboard
Game record (score, date)	On ranking submission	Ranking calculation/display
Random device identifier (generated by the app)	On first ranking submission	One record per device (anti-duplicate)
Country/region (inferred from device locale)	On ranking submission	Country-based ranking
Advertising identifier, coarse location, app interaction, diagnostics	When ads are shown (see §3)	Ad serving/measurement, error diagnostics

Ranking submission happens only when you submit a score. Otherwise your records stay on the device. The app's random identifier is separate from the advertising ID (IDFA/AAID) and is not used to track you across apps. Country/region is an inferred country code (e.g. KR); no GPS/precise location is collected.

2. Where Data Is Stored

Submitted ranking data is stored in Google Firebase (Cloud Firestore, region: Seoul, asia-northeast3).
On-device data (best scores, settings, random identifier) stays on your device only.

3. Advertising

The app is free and shows ads via Google AdMob. AdMob may collect and use an advertising identifier, coarse location, and device/usage data to serve, measure, and personalize ads. See the Google Privacy Policy and how AdMob uses data.

iOS: the device advertising ID (IDFA) is used for personalized ads only if you allow it via App Tracking Transparency.
EU/EEA & UK: a Google UMP consent screen collects your choice; personalized or non-personalized ads are shown accordingly.
You can reset the advertising ID or opt out of personalized ads anytime in your device settings.

4. In-App Purchases

The app offers a Remove Ads in-app purchase. Payments are handled by the Apple App Store or Google Play; we do not collect or store payment information such as card numbers.

5. Third-Party Services

Google Firebase (Cloud Firestore) — ranking storage
Google AdMob — ad serving/measurement
Apple App Store / Google Play — in-app purchase processing

6. Retention & Deletion

Ranking data is retained while the service operates. To delete your record, email us your nickname. On-device data is removed when you uninstall the app.

7. Children

The app is not primarily directed to children under 13 and does not knowingly collect their personal information.

8. Changes

We may update this policy; changes are posted here with a new effective date.
