JustThisOnce is designed to be simple and privacy-friendly. This page explains how local data, Game Center achievements, external services, and contact information are handled.
JustThisOnce does not collect personal data through a developer-operated server. The app is intended to work as a simple local diagnosis game, with Game Center used only for achievement features.
The developer does not operate a dedicated server to collect personal data from JustThisOnce users.
JustThisOnce may save diagnosis progress, unlocked endings, settings, and related gameplay information locally on the user's device. This local data is used to provide the app's functionality and restore the game state.
JustThisOnce uses Apple's Game Center only for achievement features. Game Center may process information such as achievement progress, player identifiers, and related Game Center data according to Apple's policies and user settings.
The developer does not use Game Center data to create a separate user profile outside Apple's Game Center service.
JustThisOnce does not include third-party advertising SDKs and does not use third-party tracking for advertising purposes.
JustThisOnce does not currently offer in-app purchases. If this changes in the future, payment processing and purchase information management will be handled through Apple's systems.
JustThisOnce may use Apple services necessary for app distribution, Game Center achievements, crash reports, and platform operation. These services are provided by Apple and are subject to Apple's own policies and user settings.
If you contact the developer for support, the information you provide in that inquiry may be used only to respond to your request.
This policy may be reviewed and updated as necessary. If there are important changes, they will be announced in the app or on related pages.
