Sortilune

Moon-cast lots: reflection and creative play with traceable randomness.

Sortilune is a personal Windows desktop app distributed as one portable executable. It has no account, telemetry, cloud service, background process, or auto-updater. Saved work remains in readable local files.

Start here

• Installation — download, run, update, and remove the portable app
• FAQ — privacy, source behavior, offline use, and practical limits
• The Entropy Engine — how public scientific signals and the labeled local fallback supply randomness

Daily and creative work

Feature	Purpose
Today	One replayable daily constellation and evening reflection
The Oracle	Draw from four built-in or installed decks
The Decider	Make a weighted choice and save a receipt
The Diary	Write locally against a generated prompt
The Constraint	Draw a small creative or observational discipline
The Canvas	Generate and export deterministic artwork
The Symphony	Hear, replay, and export a planetary score
The Beacon	Create a reproducible public-pulse checksum—not a trusted timestamp
The Lottery	Coin, dice, wheel, names, numbers, and shuffles

Workspaces and memory

• Projects — three guided multi-step creative workflows
• Practices — gentle recurring activities, rest days, skips, and reflections
• Content Packs — validated local additions for decks, prompts, constraints, Canvas palettes, and Lottery presets
• The Archive — timeline, calendar, gallery, collections, annotations, and source details
• Journal Export — self-contained HTML and Windows Print-to-PDF from selected memories

The current supported and tested release target is Windows 10/11 with WebView2. The repository may compile elsewhere through Tauri, but macOS and Linux are not release-certified targets.
