Data Stored on Your Device
We store ongoing matches, results and reviews, in-game Nyang and Knots, rival progress, language, display and sound settings, and your confirmation that you are at least 18 on your device. This supports resuming play and retaining settings. We do not transmit complete save files, card hands, or replay commands. If you enable the analytics described below, events such as starting and finishing a match are sent separately.
Nyang and Knots have no cash value and cannot be exchanged for goods or transferred to another player. They are not linked to financial accounts or payment details.
We do not ask for a date of birth or identity document. The app has no account, online multiplayer, game-data server sync, or in-app purchase feature.
Android Ads and Google Mobile Ads
The Android version uses Google Mobile Ads (AdMob) and its User Messaging Platform (UMP) for interstitial and optional rewarded ads. For ad delivery, measurement, and fraud prevention, the Google SDK may collect and send to Google your IP address (which can indicate approximate location), product interactions such as app launches, taps, and ad video views, app and SDK diagnostics, and device or app identifiers.
The app removes the Android advertising ID (AD_ID) permission and requests non-personalized ads. Even without the advertising ID, the Google SDK may process other device or app identifiers. Where required, the app presents ad consent choices; an ad privacy settings option is available in the app settings where Google requires it.
Google also governs the processing and retention of ad data. See Google’s Privacy Policy and ad controls for details. This ad data is separate from gameplay records, and Seori Labs does not link it to individual game progress.
Optional Usage Analytics and the iOS Version
From version 1.1.0, Android and iOS use Google Firebase Analytics. When enabled, analytics records installation and session events, tutorial starts and completions, match starts and results, rematch choices, daily-match completions, and ad outcomes. Events include the market, app and AI policy versions, and whether the installation is new or existing. We use these to measure first-match completion and return rates and improve the game. We do not send names, email addresses, accounts, actual card hands, or complete save files to analytics.
The SDK may process a resettable app-instance identifier, product interactions, device and operating-system information, and an approximate region inferred from the IP address. The app-instance identifier connects events and return visits from the same installation. Advertising identifiers and ad personalization signals are disabled for analytics. On iOS, we use FirebaseAnalyticsCore without IDFA capability and disable IDFV collection. We do not combine this data with other companies’ app or website data for advertising tracking.
On first launch, the analytics switch starts off and you choose whether to enable it. You can continue without enabling it and still play and save. No analytics is sent before you allow it. Change your choice later using “Share usage analytics” in Settings. Your choice remains after restarts and updates. Turning it off stops further analytics collection and resets local SDK analytics data. This does not immediately delete all information already sent to servers. Matches and saving remain available when analytics is off or the device is offline.
iOS versions 1.0.10 and earlier contain no analytics SDK. The iOS app continues to have no ads or in-app purchases. Android ad processing is described separately above.
Retention and Deletion
Local game data stays on your device until you reset it or delete the app’s data. Use “Reset all data” in app settings or your operating system’s app deletion controls. Seori Labs has no server copy of game records and cannot restore deleted matches.
If operating-system backup is enabled, that service governs backup copies. For Android ad data access and deletion choices, use your Google account and device ad settings or Google’s privacy tools. Google Analytics is configured to retain detailed event and user data for two months without extending the user-identifier retention period for new activity. Raw event tables in access-restricted Google BigQuery are retained for at most 60 days after creation and deleted when they expire. Aggregated statistics that do not identify individuals may be retained longer to improve the game. Contact us below about collection or deletion.
Support and This Webpage
If you email cs@seorilabs.com, we process your sender address and the message or attachments you choose to send so we can reply. The app does not send this information automatically. You may request access, correction, or deletion through the same address.
We retain support information as needed for the response and follow-up, then delete it unless law requires longer retention. This webpage’s hosting provider may process technical information such as your IP address; our general website policy covers that processing.
Google Play, the Apple App Store, and your operating system have their own policies for information they independently process for distribution and backups.
