Jelly Stretch : Number Puzzle · odd duck Corp. · Effective October 2, 2026 · Last updated October 2, 2026
Jelly Stretch : Number Puzzle (Korean title: 젤리 스트레치 : 숫자퍼즐, the “Service”) is a number puzzle game operated by odd duck Corp. (“odd duck”, “we”, or “us”) that is played without signing up or logging in. We process the information described below to show ads, store your game settings and profile, run the score leaderboard, and confirm purchases.
The Service has no login, so we do not collect account information such as your name, email, or phone number. The main information processed is device and app-usage data, such as your advertising identifier and IP address, for ads; your player ID, game settings and profile, game score, and connection information to save your settings and profile and run the leaderboard; and store purchase information to confirm purchases.
1.Information We Process and Why
- Advertising data — The Service shows ads from Google AdMob. When ads are shown, Google may collect and use device identifiers (such as the Android advertising ID and app set ID, and the iOS IDFA if you allow tracking), device information (such as device model and operating system version), your IP address (which may be used to estimate your general location), app and ad interactions (such as app launches, taps, ad views, clicks, and video views), and diagnostic information (such as app launch time, hang rate, energy usage, and crash logs). (Purposes: serving ads, personalized ads, ad measurement and analytics, preventing fraud)
- Game settings and profile — Your game settings and profile information are sent to and stored on our server. Connection information such as your IP address may also be sent when the app communicates with the server. (Purposes: storing your game settings and profile, providing the Service)
- Leaderboard data — When you use the leaderboard, your player ID and game score are sent to and stored on the ranking server. The player ID is a random identifier created automatically by the app. Connection information such as your IP address may also be sent when the app communicates with the server. (Purposes: compiling and displaying rankings, preventing cheating)
- Purchase data — Paid in-app items are processed by the Google Play and App Store payment systems; we do not receive payment details such as card numbers. We use purchase information provided by the store (such as product ID and order number) to confirm and restore purchases. (Purposes: confirming purchases, delivering items, restoring purchases)
- Inquiry data — If you email us a question or request, we receive your email address and the content of your message. (Purposes: responding to inquiries, handling requests)
- On-device data — Your game progress and records, in-game currency and items, language and sound settings, the player ID used for the leaderboard, and similar data are stored on your device.
2.Personalized Ads and Tracking
- iOS — The app asks whether you allow tracking, in line with Apple’s App Tracking Transparency (ATT) policy (the request may not appear, depending on your device settings). If you allow it, your IDFA may be used for personalized ads and ad measurement.
- Android — Your advertising ID may be used for personalized ads and ad measurement.
- In some regions, a consent process for personalized ads may apply under local law; where it does, you can change your choice in the way the app describes.

4.Leaderboard Rules
- Scores on the leaderboard, together with a label that distinguishes each player, may be visible to other users.
- Records we believe were submitted by abnormal means may be removed without prior notice, and that player ID may be restricted from submitting to the leaderboard.
- We may reset the leaderboard, or change or discontinue the leaderboard feature, as needed to operate the Service.
5.Device Permissions
The Service does not ask for permissions that access your personal information, such as your camera, contacts, photos, or location. It uses the permissions needed for an internet connection for ads, the leaderboard, and saving your game settings and profile, access to the advertising identifier, and store payments. On iOS, a prompt asking whether to allow tracking may appear.
6.Retention and Deletion
- Game settings and profile — Kept for as long as the Service is operated, and deleted once it is no longer needed, for example when the Service ends.
- Leaderboard data — Kept for as long as the leaderboard service is operated, and deleted once it is no longer needed, for example when the leaderboard service ends or the leaderboard is reset. Information needed to prevent cheating may be kept for as long as that purpose requires.
- Connection information (IP address) — May be processed for as long as needed to provide the Service and prevent cheating.
- Advertising data — Processed and kept under Google’s policies.

7.Your Choices and Requests
