Privacy Policy

Overview

Matchy Matchy is a browser-based game. We are committed to keeping your experience private and transparent. This policy describes exactly what data the game stores and why.

Short version: We store only game state on your own device (localStorage). No data is ever sent to any analytics service, advertising network, or third party.

Data Stored on Your Device

The game uses your browser's localStorage to save your progress and settings between sessions. No server ever receives this data. It stays entirely on your device.

• matchy-matchy-highscore — Your all-time high score
• matchy-matchy-bestchain — Your longest chain reaction achieved
• matchy-matchy-gamesplayed — Total number of games played
• matchy-matchy-totalblocks — Total blocks cleared across all games
• matchy-matchy-colorblind — Whether color-blind mode is enabled
• matchy-matchy-muted — Whether sound is muted
• matchy-matchy-rules-seen — Whether you have seen the rules popup
• matchy-matchy-daily-YYYY-MM-DD — Your score for each Daily Challenge

You can clear all of this data at any time by clearing your browser's site data for this domain.

Online Multiplayer

When you play Online Battle mode, your game state (board layout, piece positions, score) is relayed in real time to your opponent through our WebSocket relay server hosted on Fly.io. This data is used only to synchronise the live match and is not stored on the server after the match ends. No account, username, or personally identifiable information is ever collected or required.

Daily Challenge Seed

The Daily Challenge mode fetches a shared daily seed from our server . This request contains no user identifiers. The server responds with a date and a deterministic seed number only.

Third-Party Services

This game does not use:

• Analytics or tracking (no Google Analytics, Mixpanel, etc.)
• Advertising networks
• Social login or authentication
• Cookies
• Any form of user accounts or profiles

Children's Privacy

This game does not collect personal information from anyone, including children under 13. There is no registration, no communication feature, and no data collection of any kind beyond the local device storage described above.

Changes to This Policy

If we ever change this policy, the updated date at the top of this page will reflect that. We will never introduce data collection without updating this policy first.
