Local Storage Only

All game progress, statistics, and preferences (such as dark/light mode) are saved exclusively on your device using the browser's localStorage API. This data never leaves your device.

You can play without creating an account. No email address, name, or any personal identifier is required or requested.

No Third-Party Tracking

We do not use any advertising networks, analytics SDKs, crash reporting tools, or third-party trackers of any kind.

No Purchases or Payments

Zen Shikaku is entirely free. There are no in-app purchases, subscriptions, or payment flows. No financial data is ever processed by the app.

Children's Privacy

This app does not knowingly collect data from children under 13. Because we collect no data from anyone, it is safe for all ages.

Accessibility

⌨️ Keyboard Navigation
All game controls are fully accessible via keyboard. Use Tab to move between interactive elements, Enter or Space to activate buttons, and arrow keys to navigate the puzzle grid. Focus indicators are always visible.
🎨 Color & Contrast
Zensaw supports both dark and light themes. All text and interactive elements meet WCAG 2.1 AA contrast requirements. Puzzle rectangles use distinct colors that are not solely reliant on hue to convey information.
🔊 Screen Reader Support
The game uses semantic HTML and ARIA labels to describe puzzle state, grid cells, and actions. Screen reader users can navigate the interface and receive meaningful feedback when rectangles are placed or removed.
🐾 Reduced Motion
Zensaw respects the "prefers-reduced-motion" system setting. When enabled, animations and transitions are minimized or disabled entirely, providing a comfortable experience for users sensitive to motion.
📱 Touch & Motor Accessibility
Touch targets meet minimum size requirements (44×44pt) for ease of use. Drag-to-draw interactions have a tap-to-remove fallback. The layout adapts to different hand positions and assistive touch configurations.
📬 Feedback & Contact
If you encounter any accessibility barriers, please reach out via the App Store support page. We are committed to continuously improving the accessibility of Zensaw.
