A modern, Android-specific fork of Note Safe by jeerovan (now NotePrime) with Material You theming, a refined UI, and ongoing improvements. Support for other platforms will be considered in the future.
Notes app with a chat-like interface and end-to-end encrypted cloud backup/sync.
Warning
Important Migration Notice: If you are installing this fork seamlessly over the original Note Safe application, you must safely back up your data first! Because cryptographic security signatures and local database architectures may incrementally differ, please ensure you export all your notes as a secure .zip backup from within the original app before overwriting it with this version. You can then instantly restore your data inside the fork!
- Android (Fully Supported) — GitHub Releases
- Other Platforms (Planned) — Support for Windows, Linux, macOS, and iOS will be evaluated in the future.
This fork builds on the solid foundation of the original Note Safe app and completely modernizes the experience:
- Material 3 & Material You — Implements dynamic color engines that seamlessly adapt to your system palette (Android 12+), fully transforming all UI components, dialogs, and panels.
- Refined Chat UI — Overhauled the conversation view featuring asymmetric message bubbles, dynamic width constraints, dedicated swipe-to-reveal exact timestamps, and day-based visual grouping (
Today,Yesterday). - Intelligent Media Viewer — Re-engineered standard viewers to automatically scale exceptionally wide panoramas and tall screenshots, enabling natural scrolling and edge-to-edge boundary tracking with 10.0x pinch-to-zoom limits and native Save to Downloads functionality.
- Advanced Formatting — Restyled embedded location, contact, audio, and file widgets with sleek tonal backgrounds, circular borders, and contextual padding algorithms.
- Glance-Privacy Shield — Introduced a granular per-group "Privacy Shield" that blurs sensitive text and media thumbnails with a premium glassmorphic effect. Content remains hidden until revealed with a tap, strictly gating all message interactions while active.
- Advanced Security Layers — Integrated a highly robust "App-Lock Shield" featuring Screenshot Protection (blocking captures on Android) and Biometric Grace Period settings for adjustable lock delays.
- Dynamic UI Controls — Added Immersive Mode for distraction-free full-screen usage and Custom Typography support via Google Fonts integration (Inter, Lora, Roboto Mono).
- Media & Storage Management — Implemented granular Auto-Download controls (Wi-Fi vs Cellular) and a Smart Cache Utility with real-time size display and one-tap clearing.
- Sleek Menus & Settings — Standardized floating popup menus and completely refactored the settings layouts into deeply integrated Material 3 list tiles featuring inline high-precision color-picker dialogs.
