"Personal information" in this policy refers to personal information as defined under Japan's Act on the Protection of Personal Information and applicable laws.
Our basic approach
You can play the App without creating an account or signing in. Your game progress and records are saved on your device.
The information that leaves your device is limited to usage data for improving the App, the information needed to manage the Full Version purchase, and, in the free version, the information an advertising provider collects to deliver ads. Each is described below, together with where it is sent.
Information stored on your device
The following is stored on your device and is not sent to us or to any third party:
- Game progress (how far you are in the tutorial, and the state of a run in progress)
- Records for each class (best results, number of clears, unlocked depths) and your Codex (symbols, gear, and synergies you have found)
- Daily run results, and the result text prepared for sharing
- Settings (animation speed, sound effects / music / haptics / hints on or off, and your bedtime reminder hour)
- Internal app records such as a local copy of your Full Version status, how many ads you have watched, and whether a review request has been shown
Information we collect (usage analytics)
To improve the App and tune the game's balance, we collect usage data through Firebase Analytics (Google LLC). This data describes what happens in the game; it does not include your name, contact details, or other information that identifies you (the App has no text input fields).
3.1 What we collect
- Gameplay events (for example: a run started, reached a milestone, was paused, was resumed, or ended; each tutorial step; the opening or ending was shown; a screen was shown) and their values (class, depth, number of payments, spins, time taken, scores, etc.)
- Purchase screen views (including whether purchasing was available and whether a sale price was shown), and purchases started, completed, cancelled, failed, restored, or refunded (a completed purchase includes its amount and currency)
- Ad-related events (an ad was started or completed, an ad failed to load or show, etc.), your choice in the tracking permission prompt (iPhone only; allowed / denied, etc.), and the outcome of the ad consent check
- That a review request was shown, that you shared a daily result (the date of that daily run, whether you completed sharing, and an identifier of the app you chose to share to; the shared text itself is not sent), that you opened this privacy policy, and that saved data failed to load
- Usage segments (whether you have the Full Version, the deepest depth you have cleared, a range for the number of runs you have played, the App's display language, and your tracking permission status (iPhone only))
- General usage statistics that Firebase collects by default, such as app launches, sessions, device type, OS and app version, language, and approximate region (country/region) (on Android, this may include referral information about how the App was installed from Google Play)
3.2 Identifier and storage
This analytics uses an identifier that Firebase generates for each installation of the App (the app instance ID). The data is stored in Google Analytics and also in Google Cloud (BigQuery), which we use for aggregation.
Ads (free version)
The free version of the App shows ads from Google AdMob (Google LLC). These are video ads that you choose to watch to receive a bonus (such as starting a run in a deeper depth, a reroll, a trial run, or another try at the daily run), and full-screen ads shown at a break after a run ends.
- Information collected: To deliver ads, measure their performance, and prevent fraud, Google and its partners may collect device information and identifiers (including advertising identifiers: on iPhone, the IDFA if you allow tracking as described below; on Android, the advertising ID), an approximate location inferred from your IP address, information about ads shown and your interactions with them, and app performance and crash information. The App never asks for permission to use your device's location.
- Tracking permission (ATT) and advertising ID: On iPhone, after you finish the tutorial, and before ads are prepared, the App shows iOS's "Allow Tracking" prompt. The IDFA is used for ad delivery and measurement only if you allow it. Every feature of the App remains available if you don't. You can change this at any time in iOS Settings → Privacy & Security → Tracking. Android has no such prompt; you can reset or delete the advertising ID at any time in your device's Settings → Privacy → Ads (the exact path varies by device).
- Ad consent (Google UMP): In regions where the law requires consent or notice, such as the European Economic Area, the United Kingdom, and some U.S. states, the App shows a consent form from Google's User Messaging Platform (UMP), and ads are delivered according to your choices. Ads are not loaded until the required check is complete. You can change your choices at any time from "Ad Privacy Settings" on the App's Settings screen.
- Ad content: Ads are limited to content rated up to "T" (Teen) under Google's ad content ratings.
Full Version purchase (in-app purchase)
The App is free to play. A one-time purchase of the "Full Version" lets you play every class and depth without ads. There are no subscriptions.
- Payment details: Purchases are processed through Apple's App Store on iPhone and through Google Play on Android. Payment details such as credit card numbers are handled by Apple or Google; we do not receive them.
- Purchase status: To verify and restore the Full Version purchase, we use RevenueCat (RevenueCat, Inc.). RevenueCat receives purchase and transaction information, an anonymous user ID generated by the RevenueCat SDK, and basic device information such as OS and app version. We do not send your name, email address, or other contact details. On Android, after a purchase, this anonymous user ID may also be saved to your Google Account through Google's backup mechanism (Block Store) and used to carry over your purchase after you reinstall the App or change devices.
- Matching with analytics: To match purchase data with usage analytics, we share the app instance ID described in Section 3 with RevenueCat.
- Purchase facts: Purchases started, completed, cancelled, failed, restored, or refunded are also recorded in the usage analytics described in Section 3 (a completed purchase includes its amount and currency).
If you change devices or reinstall the App, you can restore a purchase made with the same account (your Apple Account on iPhone, or your Google Account on Android) using "Restore Purchases" on the Settings screen or the purchase screen.
Sharing, review requests, and contacting us
- Sharing results: Tapping the share button opens your device's share sheet. The shared text contains only game results, such as the daily run's date, class, number of payments, and best single spin. You choose where to share it, and the App never sends the text on its own. Whether you completed sharing, and an identifier of the app you chose (the activity type on iPhone, or the app's package name on Android), are recorded in the usage analytics described in Section 3.
- Review requests: On the results screen after you clear a run, the App may show the store's rating prompt (the App Store's on iPhone, or Google Play's on Android). Ratings and reviews are handled by Apple or Google; the only reviews we receive are those published on each store.
- Achievements (Game Center): Achievements are recorded on your device. If you are signed in to Game Center on iPhone, the achievements you unlock are also sent to Apple's Game Center. Your Game Center account and player information are handled by Apple, and we do not receive them. You can view your achievements in the App even without signing in. The type of achievement you unlock is also recorded in the usage analytics described in Section 3.
- Contacting us: "Contact Us" in the App opens your device's mail app. The subject line includes the app name, the app version, and the OS version. We use your email address and the content of your inquiry only to respond to you.
External services we use (third-party sharing and service providers)
We use the following external services to the extent necessary to provide and improve the App:
- Google LLC: Firebase Analytics / Google Analytics (usage analytics), BigQuery on Google Cloud (storing and aggregating analytics data), Google AdMob (ads in the free version), the User Messaging Platform (ad consent management), Google Play (distribution of the Android version, purchase processing, and the rating prompt), and Android's backup features
- RevenueCat, Inc.: managing the Full Version purchase status
- Apple Inc.: distribution of the iPhone version, App Store purchase processing, the rating prompt, the tracking permission framework, and Game Center (achievements)
International transfers
The external services above have servers outside Japan (for example, in the United States). Usage data, purchase status, and ad-related information may therefore be processed and stored outside Japan. We handle such data appropriately in accordance with applicable laws.
Security
Your game records are saved on your device and are not sent to our servers. The analytics data we send off the device does not include your name or other information that identifies you, and all communication is encrypted. If a leak or similar incident ever occurs involving information we handle, we will confirm the facts, investigate the cause, work to prevent recurrence, and take the measures required by law.
Retention and deletion
Data on your device is kept until you delete (uninstall) the App, and is erased from the device when you do (except for any copy included in a device backup as described in Section 2). Your Full Version purchase remains on record with Apple or Google and with RevenueCat, so you can get it back with "Restore Purchases" after reinstalling.
We keep the usage analytics data we collect for as long as necessary to fulfill its purpose, and delete or anonymize it appropriately once it is no longer needed.
Your rights
You may request disclosure, correction, suspension of use, or deletion of information we handle. You can change the tracking permission (iPhone) or the advertising ID (Android) at any time in your device's Settings, and your ad consent choices on the App's Settings screen (in regions where consent is required). For any other requests or questions, please contact us using the details below. After verifying your identity, we will respond as promptly as possible in accordance with applicable laws.
Children's privacy
The App is not designed to collect personal information from any particular age group. No account is required, and your game records are saved on your device. We do not knowingly collect personally identifiable information from children.
Changes to this policy
We may revise this policy in response to changes in laws or in the App. If there are significant changes, we will announce them on this page, on our website, or by other means.
