Design Principles
- Offline-first: Everything runs locally in your browser.
- No accounts: No logins, no subscriptions. Your data belongs to you.
- Fast: Pure HTML/CSS/JavaScript. No frameworks, no bloat.
- Integrated: Tools talk to each other for minimal friction.
- DM-centric: Built around real needs at the table.
- Private: No analytics, no tracking.
How It Works
- Characters, maps, journals, and settings are saved using IndexedDB.
- Your data never leaves your device.
- Import/export lets you back up or move content.
- Works offline after first load.
- Cross-tab sync keeps multiple windows in sync.
