This Privacy Policy explains how "Shelf Shuffle: Sort & Match" (the "Extension") collects, uses, and protects your information. By installing and playing the Extension, you agree to the practices described in this policy.

Information We Collect
We believe in data minimization. The Extension operates primarily offline, but collects specific data solely to power the global ranking system:

Display Name: The username you choose to enter at the beginning of the game.
Game Scores & Progress: Your level completion times and high scores.
2. How We Use Your Information
The information we collect is strictly used for App Functionality:

To display your chosen name and score on the global in-game leaderboard.
Data is transmitted securely to our backend database (Supabase) for the sole purpose of maintaining this leaderboard.
3. Local Storage
The Extension uses your browser's local storage to save your offline game progress (e.g., levels unlocked) and personal game settings. This local data never leaves your device and is not accessible by the developer or any third parties.

Data Sharing and Third Parties
We respect your privacy. We do not sell, rent, or share your data with advertisers or data brokers.

We do not collect browsing history, emails, or personal identification.
We do not run external advertisements or tracking scripts within the Extension.
Our leaderboard infrastructure is securely hosted via Supabase, which acts strictly as a data processor.
5. External Links
The Extension contains links to the developer's official itch.io page (https://nafisniloy.itch.io/shelf-shuffle). Clicking these links will open a new browser tab. We are not responsible for the privacy practices of external websites.

Data Retention and Your Rights
Your display name and score are retained on the global leaderboard indefinitely. If you would like your score and display name removed from the public leaderboard database, you can request data deletion by contacting us directly at the email provided below.
