Fusio

- > Paper‑like and enhancement notebook app - Fusio is a paper‑like enhanced notebook application built for practical note‑taking, with no‑compromise core principles. - **Privacy‑first** - All notes stay local on your device. No mandatory cloud upload, no telemetry tracking, no unauthorized data collection. Your knowledge belongs only to you. - **Mobile‑first** - Designed primarily for touch‑driven tablet & mobile usage. Optimized for stylus handwriting, gesture navigation and on‑screen annotation; keyboard input acts as auxiliary tool rather than the main workflow. - **Offline‑first** - Full feature set works completely without network. Sync is optional add‑on, not a prerequisite. Create, edit, browse and search all notes while offline. - **Engineer‑first** - Clean, maintainable codebase, open‑extensible architecture. Expose data in standard open formats, avoid proprietary lock‑in. Friendly for custom workflows, scripting and self‑modification; no black‑box AI features forced into core note logic. - **No‑AI core** - No built‑in generative‑AI chat, no automatic note rewriting, no un‑verifiable AI inference injected into your notes. Keep your thinking unaltered, human‑authored content stays pure. - Core positioning: Replicate physical paper‑book experience digitally, enhance it with computing power, while keeping user control over data and workflow. - EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula
