Nurikabe: Island Logic Puzzle Privacy Policy

Effective

This policy explains how Nurikabe: Island Logic Puzzle (the “app” or the “game”), an Android logic puzzle game published by STARRY (“we”, “us”), handles your information. Depending on your language, the game appears on your device as “Nurikabe”, “섬섬” or “島々”. This policy covers all of these.

The game is a Nurikabe puzzle: you shade cells on a grid to separate islands from the sea. It does not ask for your name or contact details, does not access your photos, camera, microphone, contacts or location, and does not use AI.

In short: the game needs no account and we run no server for it. Your progress and settings are stored on your device. Information leaves your device only through Google services built into the game: Google Play Games for optional cloud saves, Google AdMob for ads, and Google Play for purchases.

This policy covers this game only. Our other apps are covered by the general STARRY privacy policy at https://starrybits.com/en/privacy. 한국어: https://starrybits.com/seomseom/privacy

1. Information stored on your device

The game saves the following in its private storage on your device, so it can keep your progress and apply your choices:

  • Game progress: solved puzzles, best times, the board, undo history (last 200 steps) and elapsed time of puzzles you have not finished, and the last puzzle you played.
  • Daily puzzles: which daily puzzles you have solved and your daily streak (length, last day played, day revived).
  • Hints and checks: how many are left and when they refill.
  • Ad frequency: when the game was first opened, when a full-screen ad was last shown and how many puzzles you have solved since, so ads can be kept rare.
  • Purchases and themes: which items you have bought, your chosen scenery theme and when a one-day trial started.
  • Settings: sound effects, music, vibration, graphics quality, timer and live error display, tap order, language, tutorial progress and the time of your last cloud save.

This information is not sent to us. If Android backup is turned on, your device may back up and restore it according to your backup settings and Google's policies.

2. Google Play Games sign-in and cloud saves (Google user data)

Cloud saves are optional. If Google Play Games is set up on your device, the game signs in automatically; you can also sign in with Settings → Cloud save → Connect. Every puzzle and feature of the game works without signing in.

When you sign in, the game requests these Google permissions (OAuth scopes):

games, games_lite
Your Play Games player ID and gamer profile (gamer name and profile image), used to know that you are signed in. The game does not store or send this information elsewhere.
drive.appdata
Lets Play Games Saved Games store and read one progress file in a hidden, app-specific folder of your Google Drive. The game cannot see or change any other Drive files.

The cloud save contains your solved puzzles, best times, daily streak, whether you finished the tutorial, which map unlock animations you have seen, and the version of each puzzle set. It does not contain unfinished boards, settings, purchases or ad records.

The game saves when it starts, after you solve a puzzle, when it goes to the background and when you tap Sync in the settings. It always loads the cloud save first and merges it with your device's progress before saving, so a new device or a fresh install never overwrites your existing progress.

The game does not request your email address, contacts, Gmail, other Drive files or any other Google Account data. Google handles the sign-in itself, and we never receive your Google password.

We use Google user data only to save and restore your progress. We never sell, share or transfer it, never use it to serve or personalize ads, and never use it to develop, improve or train AI or machine learning models. Nurikabe: Island Logic Puzzle's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy (https://developers.google.com/terms/api-services-user-data-policy), including the Limited Use requirements.

3. Advertising (Google AdMob)

The game uses Google AdMob and the Google Mobile Ads SDK to show ads. Full-screen ads appear only when you tap Next puzzle after solving one, only every few puzzles and several minutes apart, and never in the first 24 hours after you install the game. No ad is ever shown while you are solving. Rewarded ads play only when you choose to watch one, for example to refill hints or checks, revive a daily streak or try a scenery theme for a day. If you buy Remove Ads, full-screen ads are no longer shown. When ads are requested or shown, Google may automatically collect:

  • IP address and approximate location derived from it;
  • device identifiers such as the advertising ID and app set ID;
  • interactions with the app and ads, such as app launches, ad views and taps;
  • device model, OS version, language, and diagnostic and performance data.

This information is used to deliver ads, measure ad performance and prevent fraud. Depending on your consent and ad settings, it may also be used for personalized ads.

Where required, for example in the European Economic Area, the United Kingdom and Switzerland, the game asks for your consent through Google's consent message before any ad is requested. You can review or change your choice at any time with the privacy and ad consent button in the game's settings, and reset or delete your advertising ID in your device's privacy or ads settings.

4. In-app purchases (Google Play)

Remove Ads and scenery themes are sold through Google Play Billing. Google handles your payment details under its own terms and privacy policy, and we never receive your card number or billing address.

Google Play tells the game which items your Google account owns, with an order ID and purchase token, so the game can unlock them and restore them on a new device. Google Play Console also shows us information such as the order ID, date, item, price and country of a purchase, which we use only for accounting, refunds and support.

5. Connection and time check

Hints and checks refill over time, so instead of trusting the device clock the game sends an HTTPS request to check that you are online and to read the current time. It asks https://www.google.com/generate_204 and, if that fails, https://www.cloudflare.com/cdn-cgi/trace.

These requests contain no game records or personal information. As with any internet request, your device's IP address reaches Google's or Cloudflare's servers and is handled under their policies.

6. Contacting support

If you email us at support@starrybits.com, we receive your email address and whatever you include in your message. We use them only to answer you, and delete them when they are no longer needed, unless the law requires us to keep them for longer.

7. Permissions

Internet and network state
Load ads, process purchases, sync cloud saves and check the connection and time. The puzzles themselves are built into the game.
Advertising ID
Used by Google AdMob to show ads, subject to your consent and device settings.
Google Play billing
Lets Google Play process in-app purchases.

The game does not request access to your location, contacts, camera, microphone, photos or files.

8. Third-party services and international transfers

We do not sell, rent or share your personal information with anyone. Google Play Games, Google AdMob and Google Play process information under Google's own policies, and that information may be transferred to and processed on servers outside the Republic of Korea, including in the United States.

9. Retention and deletion

  • Information on your device: uninstall the game, or clear its data in Android Settings → Apps → Nurikabe → Storage.
  • Cloud saves: delete the game's data in the Google Play Games app under Settings → Delete Play Games account & data, or in Google Drive on the web under Settings → Manage apps → 섬섬 (the game's name in Google services) → Delete hidden app data.
  • Purchases: kept by Google Play with your Google account so you can restore them. Clearing the game's data does not remove them.
  • Ad data: retained and deleted under Google's policies. We cannot view individual records held by Google.
  • Support emails: deleted once your request is resolved and they are no longer needed, unless the law requires otherwise.

10. Children

The game is a general-audience puzzle game. It is not directed at children under 13 (under 14 in Korea), and we do not knowingly collect personal information from children. If you believe a child has sent us personal information, for example by email, contact us and we will delete it.

11. Your choices and rights

Depending on where you live, laws such as the GDPR, the UK GDPR, California privacy law and Korea's Personal Information Protection Act may give you rights to access, correct, delete or restrict the processing of your personal information, and to object to it.

  • Change your ad consent with the privacy and ad consent button in the game's settings, where available in your region.
  • Reset or delete your advertising ID, or opt out of personalized ads, in your device settings. You may still see ads that are not personalized.
  • Sign out of Google Play Games, or delete your cloud save as described in section 9.

For any other request, email support@starrybits.com. We reply within 10 days.

12. Security

  • With no developer server, user data is never gathered in one place.
  • Data stored on your device is kept apart from other apps by Android's app sandbox.
  • Cloud saves, ads and purchases use encrypted connections (HTTPS) provided by Google.
  • Only the minimum Google permissions needed for saving progress are requested; drive.appdata is limited to the game's own folder.

13. Changes to this policy

We may update this policy when the game's features, the external services it uses or the applicable laws change. We will post the update on this page at least 7 days before it takes effect (30 days for changes that are less favorable to you), and give notice in the game for material changes.
