DREAMBOOK · MAX MIN SWITCH
Privacy Policy
Last updated: October 13, 2026
1. Scope
Hyangryul Bae (DreamBook) provides the Max Min Switch app and its support website. This policy describes the current version’s information practices. The app has no developer-operated accounts, advertising SDKs, analytics SDKs or feature that sends data to a developer-operated server.
2. Information stored on your device
The app stores your app nickname, best score, game and practice completion flags, language, sound and vibration preferences, and whether a Game Center connection was attempted. To retry score submissions, it may store your game-scoped player identifier and a pending score on your device. Your app nickname is not sent to Game Center. Operating-system backups and restoration may separately include app data depending on your device settings.
3. Optional Game Center connection
You can play without connecting to Game Center. When you connect, Apple provides authentication and the service. The app uses your sign-in status, game-scoped player identifier, display name and ranking information. Scores from completed rounds after connecting are automatically sent to Apple Game Center. Practice, abandoned rounds and local best scores saved before connecting are not automatically submitted. Failed submissions are kept on your device and retried when connected; the corresponding pending record is removed after successful submission. Failed pending records have no separate expiry period.
4. Online score visibility and management
Your Game Center name, scores and related information may be visible to other players according to Apple’s sharing settings and service rules. The developer does not receive your Apple Account password. See Apple’s policies and your device’s Game Center settings for Apple’s processing and account or visibility controls. Deleting the app does not delete online records held by Apple.
5. Permissions and diagnostics
The app does not request access to your camera, microphone recording, location, contacts or photo library. Sound effects play bundled audio files. Error information may appear in device system logs, but the app has no custom log-upload feature. Operating-system diagnostic sharing is governed by Apple and your device settings.
6. Support inquiries you send
When you email support, the support contact receives your email address, message and any files you choose to attach. This information is used to answer your inquiry and resolve issues, and retained only as long as needed for those purposes and applicable retention obligations. Do not send Apple Account passwords, verification codes or unnecessary personal information. Contact us below to request deletion of support correspondence. We will explain any retention needed to handle your inquiry or meet applicable retention obligations.
7. Support website
Cloudflare Pages hosts the support website. We have not added advertising or analytics scripts or a contact form. Cloudflare may process IP addresses and technical access information to deliver and secure the website. Email links open your email app; your inquiry is not sent to the developer until you send it.
8. Retention and deletion
On-device information is retained while you use the app. You can change your nickname and preferences in the app’s settings. Completely deleting the app generally removes its local data; offloading preserves data, and restoring a backup may restore it. Apple manages Game Center information separately. There is no separate membership account operated by the developer.
9. Changes and contact
If information practices change, we will update this page and its revision date. For privacy questions or support, contact dreambookapps@icloud.com.
