Zenit Week

A visually rich, single-file mind-map week planner that runs entirely in your browser. No server, no database, no complex setup—just one HTML file.

🚀 Quick Start

Online: Open zenitweek.com and start immediately — nothing to install.

Offline: Download zenit-week.html and open it in any modern web browser (Chrome, Firefox, Safari, Edge). Your data is automatically saved to your browser's localStorage.

✨ Features

• Mind Map Interface: Visualize your week as a branching tree of activities.
• Customizable Branches: Start with Work, Family, and Me; add or delete branches, and change their colors with the built-in color picker.
• Priority Levels: Mark tasks as Normal, High, or Critical — priority scales visual layout spacing and cascades to child nodes.
• Dynamic Counters: Add Nx to any task name (e.g., "Pushups 10x") to track progress with a clickable counter.
• Day Indicators: Add (mo), (we, fr), or (daily) to any activity name to schedule it for specific weekdays in the daily list. Multiple days work with spaces or commas: (mo, we, fr).
• View Levels: Switch between Sand (all nodes), Pebbles (hide deep sub-tasks), and Rocks (main branches only) to control visual depth. Swipe on mobile to cycle levels.
• Reusable Tasks: Mark tasks as Reusable and carry them forward each week with counters reset.
• Drag & Drop: Easily reorder tasks or rebind them to different parent nodes.
• Cross-Week Transfer: Move all unfinished tasks from the previous week; or transfer only Reusable tasks; or move a single node (with its subtree) to the next week.
• Effort Baseline: Set a weekly activity count that represents a safe load — the summary panel warns when you're over it.
• Daily Log: View a summary of completed and ticked activities for the day, with timestamps.
• Todo Panel: Quick sidebar listing all incomplete tasks across the week.
• Export / Import: Back up all your weeks to a JSON file and restore them on any device from Settings.
• Dark Mode: Full light/dark theme with automatic detection of system preference.
• Undo/Redo: Full history support with 100 levels of undo.
• Google Drive Sync: Optionally sign in with Google to sync your data across devices — stored only in your own Google Drive.
• Internationalization: UI available in English and Czech; language selector in Settings, persisted across devices via Drive sync.
• Privacy First: Zenit Week has no servers and stores nothing itself. Your data lives on your device (localStorage) or in your own Google Drive — it never touches our infrastructure.
