Glimmergrid Privacy Policy
- App name: Glimmergrid (Google Play package name: com.sbgc.glimmergrid)
- Data controller: Kim Seunghoon, individual developer (Google Play developer name: s.h.)
- Effective date: November 20, 2026
- Last updated: November 3, 2026
Kim Seunghoon (the "developer") processes the personal information of people who use Glimmergrid (the "app") in accordance with the Personal Information Protection Act of Korea and other applicable laws. This policy explains what information the app stores, where it goes, and how you can make choices and exercise your rights.
Summary
- The app has no sign-up. The developer runs no servers of its own and uses no analytics tools.
- Your game records, settings and the names you enter for two-player mode are stored only on your device and are not sent to the developer.
- When you see ads (Google AdMob), use Play Games, or pay through Google Play, the information needed for that feature is sent to Google LLC. You can play the whole game without signing in to Play Games.
- The daily reminder works only if you turn it on, and the app asks for notification permission only at that moment.
- Depending on your region, you can refuse or change your consent to personalized ads inside the app.
1. Information we process and why
1.1 Information stored only on your device
| Item | Purpose | Kept until |
|---|---|---|
| Settings (animation, display, sound, vibration, daily reminder on/off), language, tutorial status, whether one-time notices were shown | Keep your app settings | You uninstall the app or clear its data |
| Player names you enter for two-player mode (up to 8 characters) | Show names on the two-player screens and results, and fill in the last names next time | You uninstall the app or clear its data. Replaced when you change them |
| Game in progress, last game result | Resume a game, show the result again | The game ends or the next result replaces it |
| Daily puzzle records (date, score, order of stars placed, time finished, etc.), best scores for past skies | Redraw results, trends, streaks, achievements, past-skies feature | You uninstall the app or clear its data |
| Collection, totals, achievement progress | Provide game features | You uninstall the app or clear its data |
| If you installed the app from a shared link: the sky date in that link, and whether the check is done | Open the sky your friend shared, once | The date is removed when you finish or skip the tutorial. The check flag stays until you uninstall the app or clear its data |
| Premium purchase status (cache) | Show purchase status offline | Checked again with Google Play at app start |
| Ad consent choice, ad interval counters | Apply your choice, limit ad frequency | You uninstall the app or clear its data |
| Result of the Korea region check | Show the ad notice screen to users in Korea | You uninstall the app or clear its data |
- Two-player names are used only to show whose turn it is when two people take turns on one device. You do not need to use a real name; if you leave them blank, the default names (Player 1, Player 2) are used. These names are not sent to leaderboards, share cards or Google.
- Shared-link date: once, on the first launch after install, the app reads the install referrer (Play Install Referrer API) from the Google Play Store app on your device. Only if you installed the app from this app's share link does it extract and store the date in that link (for example, 2026-11-23). It does not store any other referrer content or the click and install times. This happens only on your device; nothing is sent to the developer or anywhere else. Source: https://developer.android.com/google/play/installreferrer/library
- Daily reminder: if you turn it on, the app uses the device's alarm function to show, on the device, one notification a day saying a new sky is open. The notification content and time are not sent anywhere.
- The app decides whether you are in Korea by checking, on the device, the SIM country, network country, device region setting and time zone. Only the result is stored on the device. It is not sent anywhere, and the app does not ask for location permission.
- None of this information is sent to the developer, and the developer cannot see it.
1.2 Information sent to Google
| Feature | Information sent | Purpose | Required? |
|---|---|---|---|
| Ads (Google AdMob, Google User Messaging Platform (UMP)) | IP address (may be used to estimate general location), device identifiers such as the advertising ID and app set ID, ad-related interactions such as app launches, taps and video views, diagnostic information such as app performance, your ad consent choice. If an error occurs in the ad feature, the Google Mobile Ads SDK may send error details (stack information) and device information (device type, OS version, memory status, app version) to Google. App code content is redacted before it is sent | Show and measure ads, prevent fraud, apply your consent choice, checking ad feature errors | Needed to show ads. Personalized ads are optional (Section 2). Sending error information cannot be turned off by the user |
| Play Games (Play Games Services) | If you are signed in: Play Games player ID, profile name and avatar, daily puzzle scores, achievements. Also analytics and diagnostics data that the Play Games SDK collects automatically | Daily puzzle leaderboard and achievements. Google uses the analytics and diagnostics data to keep the SDK stable and improve its products | Optional. You can play the whole game without signing in (see automatic sign-in below) |
| Google Play billing (one-time Premium purchase) | Purchase records (product, purchase status, etc.) | Process payment, verify and restore purchases | Payment only when you buy. To check purchase status, the app asks Google Play for this app's purchase records at start, when it returns to the foreground and when you open the shop |
- The ad items above are based on Google's published data disclosure for the Google Mobile Ads SDK: https://developers.google.com/admob/android/privacy/play-data-disclosure
- Play Games Services tries to sign you in automatically when the app starts. If a Google Account on the device has a Play Games profile, you may be signed in without tapping anything, and while you are signed in your daily puzzle scores and achievements are submitted to Play Games automatically. If you have no profile, Google may suggest creating one; you can keep playing without it. Source: https://developer.android.com/games/pgs/android/android-signin
- The Play Games items above are based on Google's published data disclosure for the Play Games Services SDK: https://developer.android.com/games/pgs/data-collection
- Payment details such as card numbers are handled by Google. The developer does not receive them. The app handles only the purchase information needed to check purchase status on the device, and stores only whether Premium is owned.
1.3 Information you send us
| Item | Purpose | Kept until |
|---|---|---|
| Email address, message content | Answer your inquiry, handle rights requests | Deleted without delay once handled, unless the law requires us to keep it for a set period |
1.4 Sky cards you share
When you tap share on a daily puzzle result, a sky card image (app name, puzzle number, date, your sky, score against the day's baseline, sky label, and whether you completed the shape of the day), a short line of text and a Google Play Store link (including the date you shared) are passed to your device's share screen. The card and link contain no name, account, device identifier, location or ranking. They go only to the app you choose (such as a messenger), and that app's policy applies after that. The developer does not receive what you share. The card image is created in the app's private temporary folder for sharing and is deleted the next time you share.
1.5 Information we do not collect
- We do not ask for your phone number, address, date of birth or similar personal details. Two-player names are stored only on your device, as described in Section 1.1.
- The app does not request location, contacts, photos/storage, camera or microphone permissions.
- The App does not use its own crash reporting or analytics tools. However, the Google Mobile Ads SDK may send error details to Google when an error occurs in the ad feature; this information is described in section 1.2. Information collected by the Play Games SDK on its own is also described in section 1.2.
1.6 App quality data from Google Play (Android vitals)
Google Play collects quality data, such as app crashes and "app not responding" events, from a subset of devices whose users have turned on automatic sharing of usage and diagnostics data, and gives it to the developer through Google Play Console (Android vitals). Google collects this at the device level, not through the app, and whether it is collected depends on your device settings. The developer uses it only to fix errors and improve quality.

1.7 Closed test builds
In closed test builds, the [About] screen has an item for copying test statistics. Tapping it copies app usage statistics, such as games played, win rates, screen size, Android version and AI calculation time, to your device clipboard. Nothing is sent automatically. The statistics contain no account, name (including two-player names), advertising ID or device identifier. The developer receives them only if a tester pastes and sends them, and uses them only to analyze test results. The public release build does not have this feature.
2. Ads and your choices
The app shows ads so it can be offered for free. The app does not start the ad SDK until it has checked with Google UMP whether consent is required in your region. The in-app ad choice item is at [Settings] > [Privacy & account] > [Your privacy choices], and the same item also appears on the [About] screen. It is shown or hidden depending on your region, as described below.
2.1 Users in Korea
- On first launch, an [About ads] screen asks whether you agree to personalized ads. You can choose [I'm 14 or older, agree] or [Don't agree].
- If you choose [Don't agree] or do not answer, the app requests only non-personalized ads. Gameplay is the same either way.
- You can change your choice at any time at [Settings] > [Privacy & account] > [Your privacy choices].
- Only users aged 14 or older may choose [I'm 14 or older, agree]. The app does not have a process to obtain and verify a legal guardian's consent, so if you are under 14, please choose [Don't agree]. If you already chose [I'm 14 or older, agree], you can change it in [Your privacy choices].
- Even on a device judged to be in Korea, if Google determines that the device needs consent under the rules of the EEA, the UK or Switzerland, Google's consent screen in Section 2.2 appears instead of [About ads], and the app then requests only non-personalized ads regardless of your choice.
2.2 Users in the European Economic Area (EEA), the UK and Switzerland
- On first launch, Google's consent screen appears.
- You can change your choice or withdraw consent at any time at [Settings] > [Privacy & account] > [Your privacy choices].
2.3 Residents of certain US states
Users in California, Colorado, Connecticut, Delaware, Florida, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah, and Virginia can opt out of the sale or sharing of personal information at [Settings] > [Privacy & account] > [Your privacy choices].
If you opt out, your choice is passed to Google, data processing is restricted, and personalized ads are not shown. You can change this choice at any time in the same menu. The developer does not sell personal information for money.
2.4 Users in other regions
The in-app ad choice item is not shown. You can manage ads in these ways:
- Reset or delete your advertising ID in your device's ad settings (the menu location depends on your device and Android version)
- Google My Ad Center: https://myadcenter.google.com
2.5 Automatic collection tools
The app does not use cookies or tracking tools of its own. The ad SDK collects the information in Section 1.2, and you can refuse personalized ads as described in Sections 2.1 to 2.4. If you do not want the information needed to show ads to be sent at all, please stop using and uninstall the app.
3. Retention and deletion
- Information on your device: deleted immediately when you uninstall the app or clear its storage data in your device's app info settings. App data is excluded from Android backup, so it is not restored if you reinstall the app.
- Information sent to Google: kept by Google under Google's Privacy Policy: https://policies.google.com/privacy
- Inquiry emails: deleted from the mailbox and trash without delay once handled. If the law requires us to keep something, we keep only that item for the required period and then delete it.
4. Sharing with third parties and international transfers
The developer does not sell your personal information. Because the app uses Google services, information is sent outside your country as shown below when you use the related feature. We do not share it with anyone else, except in response to lawful requests such as from law enforcement. The developer does not outsource the processing of personal information to any other company.
| Recipient | Information | Country | When and how | Purpose | Retention | How to refuse, and the effect |
|---|---|---|---|---|---|---|
| Google LLC (ads: AdMob, UMP) | Ad items in Section 1.2 | United States and other countries where Google operates servers | Sent over the internet when the app requests or shows ads | Show and measure ads, prevent fraud | Per Google's policy | Refuse personalized ads as in Section 2. Transfers needed to show ads cannot be refused while using the app; if you do not want them, uninstall the app |
| Google LLC (Play Games) | Play Games items in Section 1.2 | United States and other countries where Google operates servers | Sent over the internet when, while signed in (including automatic sign-in), scores or achievements are submitted or rankings are viewed, and when the Play Games SDK sends analytics and diagnostics data | Leaderboard and achievements, SDK improvement | Per Google's policy | If you do not sign in, no scores, achievements or profile information are sent. Only the leaderboard and achievements are unavailable. Submitted data can be deleted as described in Section 6 |
| Google LLC (Google Play billing) | Purchase records | United States and other countries where Google operates servers | Sent through Google Play when you buy, and when purchase status is checked or restored at app start, on return to the foreground or on entering the shop | Process payment, verify purchases | Per Google's policy | If you do not buy, no payment details or purchase records are created. Only Premium features are unavailable |
| Google LLC (Gmail, inquiry emails) | Email address, message content | United States and other countries where Google operates servers | When you send us an email | Answer your inquiry | Section 3 | Nothing is sent if you do not email us |

5. Security measures and app permissions
As an individual developer, the developer takes the following measures.
- There is no developer server or developer account system, so the developer does not gather or store users' personal information.
- Game data and two-player names are stored in the app's private storage, which Android keeps other apps from accessing, and are excluded from Android backup.
- The app does not request location, contacts, storage, camera or microphone permissions.
- The only permission the app asks you for is notification permission. On Android 13 and later, the app asks only when you turn on the daily reminder (by choosing to turn it on in the reminder suggestion, or by turning on the daily reminder in [Settings]). If you do not allow it, the daily reminder stays off and gameplay is the same. You can change this at any time in your device's app notification settings.
- The other permissions the app uses are normal permissions that the app does not ask you for: internet access, network state, vibration, Google Play billing, receiving the device boot-completed event (used, if the daily reminder is on, to schedule the reminder again after the device restarts or the app is updated), connecting to the Google Play install referrer service (Section 1.1), and the advertising ID, ad measurement and background work permissions used by the ad SDK.
- The developer does not receive payment details.
- Inquiry emails are read only by the personal information protection officer.
- Google states that data sent by the ad SDK is encrypted in transit using TLS, and that data collected by Play Games Services is encrypted in transit using HTTPS.
- If the developer becomes aware of a personal information breach, the developer will notify affected users as required by law and, where required, report it to the Personal Information Protection Commission or the Korea Internet & Security Agency.
6. Your rights and how to exercise them
You (or a legal guardian, for a child under 14) can ask to access, correct, delete or stop the processing of personal information, and can withdraw consent. The only personal information the developer keeps directly is inquiry email, so most rights can be exercised yourself as follows.
- Delete data on your device: uninstall the app, or clear its storage data in your device's app info settings.
- Two-player names: edit or clear them at any time on the two-player setup screen.
- Daily reminder: turn it off at [Settings] > [Gameplay], or turn off notifications in your device's app notification settings.
- Change or withdraw ad consent: follow Section 2.
- Advertising ID: reset or delete it in your device's ad settings.
- Play Games: sign-in is optional, and you can sign in at [Settings] > [Privacy & account] > [Play Games]. If the device has a Play Games profile, you may be signed in automatically when the app starts (Section 1.2). The app has no sign-out menu. You can delete this game's Play Games data and your profile in Google Play's Play Games profile settings: https://support.google.com/googleplay/answer/9130646
- Purchase records: see your Google Play purchase history in your Google Account. You can reload your purchase status at [Settings] > [Privacy & account] > [Restore purchase].
- Other requests: email us at the address in Section 9. We will reply within 10 days of receiving your request. If we cannot finish within that time, we will tell you why and when we expect to finish. We may ask for additional information only as needed to confirm that the request comes from you.
7. Children's privacy
The app is intended for users aged 13 and over and is not directed at children under 13. The developer does not knowingly collect personal information from children. In Korea, where consent is required to process the personal information of a child under 14, the consent of a legal guardian is required. The app does not have this process, so it does not ask users under 14 to consent to personalized ads (Section 2.1). If you believe a child's personal information is being processed, please let us know at the email address in Section 9.
