This application sets forth the following privacy policy regarding the handling of Users' personal information in "PKDataNavi."
- This Privacy Policy respects the privacy of Users and ensures careful handling of Users' personal information and access information.
- Regarding Analytics Services: To understand app usage and improve stability, we use Google Analytics and Firebase (including Firebase Analytics and Firebase Crashlytics, provided by Google LLC). These services may automatically collect device identifiers, OS version, app usage data, and device state and error information when the app crashes. We do not link this information to your name, address, telephone number, or similar personal details. The information collected, purposes of use, and sharing with third parties are governed by Google's Privacy Policy.
- Regarding In-App Advertisements: This app uses AdMob (Google LLC) to deliver advertisements. The following information may be collected automatically for ad delivery and measurement:
- Advertising identifier (IDFA on iOS, Android Advertising ID on Android)
- Device information (OS version, device model, language settings)
- Approximate location (country or region inferred from IP address)
- App usage and ad interaction history
On iOS, the app displays an App Tracking Transparency dialog requesting permission to track. If permission is granted, personalized ads using the advertising identifier will be delivered. If permission is not granted, non-personalized ads will be delivered without using the advertising identifier. App functionality is not restricted based on this choice.
You can change this setting at any time:
- iOS: Settings → Privacy & Security → Tracking
- Android: Settings → Google → Ads → Opt out of Ads Personalization
Details of the information collected, purposes of use, and sharing with third parties are governed by Google's policies:
- About Free Text Fields in the App: Users are requested not to enter personally identifiable information such as their name, address, phone number, or email address in the free text fields within the app.
The app operator does not intend to collect such information, and any such entries may be promptly deleted.
Please note that the operator shall not be held responsible for any issues or troubles arising from the input of personal information.
- Handling of Match Result Data Entered by Users: This application collects and uses information entered by Users regarding match results (such as deck names, win/loss outcomes, and opponent deck names) for the purposes of service improvement, trend analysis, and the publication of statistical data on social media or other external platforms.
Such information is aggregated and processed into statistical data in a format that does not identify individual Users, and only this anonymized statistical data may be made publicly available.
When a dispute report is submitted through the PK Match feature, the screenshots and match information provided at the time of the report will be made available to an unspecified number of app users for the purpose of community voting. Additionally, ratings and win/loss records may be displayed to other users on rankings and similar screens. This information may continue to be displayed even after the account is deleted.
- Handling of Subscription Information: To manage Premium Plan subscriptions, this application collects and stores the following information:
- Subscription status (active/inactive)
- Subscription start date
- Subscription expiration date
- Payment platform (App Store or Google Play)
- Transaction ID (for purchase verification)
This information is used solely for service provision, fraud prevention, and user support, and will not be shared with third parties. However, for payment processing and purchase verification, services provided by Apple Inc. and Google LLC are utilized, and information is processed in accordance with their respective privacy policies.
- Use of Connection Information and Related Data for Fraud Prevention: The PK Match feature of this app may use users' IP addresses for the purpose of preventing fraudulent multi-account matches (match manipulation) by the same user. IP addresses are converted to a hash value, and only this hash value is temporarily stored on the server while a user is waiting in the matchmaking queue. The hash value is promptly deleted upon match confirmation or queue cancellation, is used solely for matchmaking verification, and will not be shared with third parties.
Separately, the server's access logs record IP addresses for up to 30 days for operational and fraud prevention purposes.
In addition, to prevent fraudulent multi-account matches and the evasion of match records or penalties by deleting and re-creating accounts, the identifiers (account IDs) of accounts previously signed in on the same device are stored and linked to any newly created account. This information is used solely for investigating and preventing fraudulent use and will not be shared with third parties.
- Data Deletion: You can delete your account and stored data from the "Other" screen within the app. If deletion within the app is not possible, or if you wish to request deletion by other means, please contact us using the details at the end of this page. We will delete the data promptly after confirming the request comes from the account holder.
However, even after you delete your account, the following information remains on the server in order to display other users' match histories and rankings and to prevent fraudulent use:
- PK Match records of matches you participated in (the name used at the time of the match, ratings before and after the match, deck information, and the content of win/loss reports)
- Screenshots submitted with win/loss reports
- Records of community votes and reports
- Past season rankings (rank, name, and results)
- Matchmaking queue records (queue start time, rating, and matchmaking result)
- Identifiers of accounts previously used on the same device (see Section 7)
- Server access logs (including IP addresses, for up to 30 days; see Section 7)
This information is retained for as long as the service is provided. Server access logs, however, are automatically deleted after up to 30 days.
In addition, your profile image and the device token used to send push notifications may remain on the server after your account is deleted.
Upon termination of the service, user data will be deleted promptly.
