Effective Date: December 16, 2025

The developer of the Decision Maker app, Marek Liška, respects your privacy. This policy explains how my app handles data.

1. Overview

The app does not collect, send or share any personal data of users.
Decision Maker is designed as an offline tool. All processes take place locally on your device.

2. What data we store and why

The app stores data only in the internal memory of your device, which only this app has access to.

• App settings: Your preferences (language, dark/light mode, left-handed mode, history length) are stored using SharedPreferences technology.
• Decision history: The results of your choices are stored in a local database (SQLite). This data is used solely for your retrospective viewing in the History section.
• User lists: If you use the „Custom Order“ feature and save your list, the application will create a local file in the application’s dedicated storage.

3. Application permissions

The application does not require any sensitive permissions of the Android operating system.

• No Internet: The application does not have access to the network, data cannot be sent out.
• No location: We do not track your location.
• No contacts or media: The application does not read your contacts or photos.

4. Data management and deletion

The user has full control over their data:

• History: It can be deleted at any time in the application settings or set to be automatically deleted after a selected period of time.
• Lists: Saved lists can be deleted individually directly in the list editor.
• Uninstall: Uninstalling the application will permanently delete all data associated with the application from your device.

5. Ads and Analytics

The application does not contain any advertising systems (Ads) or third-party analytics tools (such as Google Analytics or Firebase) that track user behavior.
