This Privacy Policy explains how LuckEngine (“the App”) collects, processes, and protects information. LuckEngine is a probability simulation and analysis tool designed to model random events, perform statistical calculations, and track experimental data.
The App is designed with a focus on transparency, local data storage, and user control.
By using LuckEngine, you agree to the practices described in this Privacy Policy.
LuckEngine does not require account registration to use its core features.
The App may process the following categories of information.
Dice configurations and roll parameters
Custom dice definitions
Deck configurations and draw sequences
Simulation settings for Monte Carlo experiments
Inputs for probability calculators (e.g., distributions, variables, constraints)
Logged outcomes from dice rolls, card draws, or coin flips
Named experiment sessions in the Entropy Ledger
Recorded results and timestamps
Notes or annotations added by the user
Generated probability distributions
Statistical summaries (expected value, variance, standard deviation, etc.)
Visualizations such as charts and heatmaps
When AI-powered features are used, the App may process:
Images of game boards submitted for probability analysis
Text prompts related to probability theory or game scenarios
Logged experiment data analyzed for pattern detection
AI features activate only when the user explicitly initiates a request.
If you contact support, we receive your email address and any information voluntarily included in your message.
LuckEngine operates primarily as an offline-first application.
Simulation data, experiment logs, custom configurations, and analytical results are stored locally on the user’s device using secure operating system storage.
Experiment history and visualizations remain on the device unless the user exports or shares them.
When AI tools are used, relevant data (such as images or prompts) is securely transmitted to external AI processing services to generate responses. These transmissions occur only when initiated by the user.
Exported experiment reports or datasets are generated locally and shared using the device’s file-sharing system.
Deleting the App removes locally stored data unless it has been backed up through the device’s operating system.
LuckEngine may rely on third-party services for:
AI processing infrastructure
App marketplace distribution
Optional crash diagnostics for performance improvements
These services operate under their own privacy policies.
LuckEngine does not include advertising networks and does not sell or share user data.
All probability calculations, simulations, and statistical analyses — including Monte Carlo simulations and distribution modeling — are performed locally on the device.
AI-generated insights are produced only when users submit data through AI tools.
LuckEngine does not track user activity across applications and does not collect advertising identifiers.
Any internal analytics are limited to application performance and reliability.
Users maintain full control over their data.
You may:
Edit or delete experiment sessions
Remove logged outcomes and notes
Delete custom dice or simulation presets
Clear calculation history
Remove AI-generated insights
Permanently erase all stored data by deleting the App
If future cloud synchronization features are introduced, users will be provided with tools to manage and delete stored data.
LuckEngine uses standard security measures including:
Encrypted transmission (HTTPS) for AI requests
Application sandboxing within the device operating system
Local storage protected by system-level security
Users are encouraged to enable device passcodes or biometric authentication for additional protection.
While no system can guarantee absolute security, LuckEngine minimizes exposure by limiting external data transmission.
Future versions of LuckEngine may introduce:
Cloud backup for experiment data
Cross-device synchronization
Collaborative experiment sharing
Expanded AI analysis capabilities
Any feature involving external data storage will require explicit user activation and clear documentation.
LuckEngine is intended for general audiences including students, but is not specifically directed toward children under the age of 13.
The App does not knowingly collect personal information from children.
This Privacy Policy may be updated periodically to reflect new features, technical improvements, or regulatory requirements.
Significant updates will be communicated within the App. Continued use of LuckEngine indicates acceptance of the updated Policy.
