1. Introduction
Cube Master ("we", "our", or "the App") is a fully offline 3D Rubik's Cube simulator and training timer. Your privacy is a core design principle of this App. This Privacy Policy explains what data the App does and does not handle.
By using Cube Master, you agree to the practices described below.
2. Information We Do NOT Collect
Cube Master is designed to run entirely on your device without any server communication. We do not collect, transmit, or store any of the following:
- Personal identifiers (name, email, phone number, Apple ID)
- Device identifiers (IDFA, IDFV, advertising identifiers)
- Location data
- Contacts, photos, files, or other personal content
- Usage analytics, session data, or crash reports
- Payment or financial information
3. Data Stored on Your Device
The App saves the following information locally using Apple's UserDefaults. This data never leaves your device:
- Solve records (date, duration, move count)
- Preferences (language, haptics, sound, dark mode)
You can remove all stored data at any time by deleting the App from your device or by tapping "Clear All Records" in Settings.
4. Third-Party Services
Cube Master does not integrate any third-party analytics, advertising, social, authentication, or tracking SDKs. The App has no network permissions and makes no outbound network requests.
5. Data Security
Because all data is kept locally and is never transmitted, the security of your data depends on the security of your device. We recommend enabling a device passcode, Face ID, or Touch ID to protect your iPhone.
6. Data Deletion
You have complete control over your data:
- Clear in-app: Open the Records tab and tap "Clear All Records".
- Uninstall: Deleting Cube Master from iOS will remove all locally stored data.
7. Children's Privacy
Cube Master does not knowingly collect personal information from anyone, including children under the age of 13. The App is safe for use by children because it collects no data at all.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be reflected by an updated "Last updated" date at the top of this page. Continued use of the App after changes constitutes acceptance of the updated policy.
