1. Introduction

Welcome to Tetris Online ("we," "our," or "us"). We are committed to protecting your privacy and ensuring you have a positive experience on our website and when using our services.

This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website onlinetetris.org and play our Tetris Online game. Please read this privacy policy carefully.

2. Information We Collect

2.1 Information You Provide

• Game scores and statistics when you play our Tetris game
• Username or player identifier (automatically generated)
• If you choose Google sign-in, Google account identity information (including email and profile information) is processed by Supabase Auth to authenticate you. We store your game nickname and links between your account and guest player IDs. Your Google email and real name are not displayed on the leaderboard.
• Feedback or comments you may provide

2.2 Information Automatically Collected

• Browser type and version
• Device information (type, operating system)
• Pages visited and time spent on our website
• Game play data and performance metrics

2.3 Local Storage Technologies

We use local storage technologies (not cookies) to store your game settings and preferences locally on your device. If you sign in, we also store your login session locally and send authentication tokens to our backend to save and retrieve your account data. Completed game scores and player identifiers are submitted to the leaderboard.

3. How We Use Your Information

We use the information we collect for the following purposes:

• To provide and maintain our gaming service
• To display leaderboards and game statistics
• To improve our website and gaming experience
• To analyze usage patterns and optimize performance
• To prevent fraud and ensure fair play
• To respond to your inquiries and provide customer support
• To comply with legal obligations

4. Information Sharing and Disclosure

We do not sell, trade, or otherwise transfer your personal information to third parties, except in the following circumstances:

4.1 Legal Requirements

We may disclose your information if required to do so by law or in response to valid requests by public authorities.

4.2 Public Information

Game scores and usernames displayed on leaderboards are considered public information and may be visible to other users.

5. Data Security

We implement appropriate technical and organizational security measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include:

• Encryption of data in transit and at rest
• Regular security assessments and updates
• Access controls and authentication measures
• Secure hosting infrastructure

However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

6. Data Retention

We retain your personal information only for as long as necessary to fulfill the purposes outlined in this Privacy Policy, unless a longer retention period is required or permitted by law.

• Game scores uploaded to leaderboards: Retained indefinitely for competitive purposes
• Local game settings and preferences: Stored locally on your device until you clear them
• Usage analytics: Retained for up to 2 years
• Log files: Retained for up to 1 year

7. Local Storage

We use local storage technologies to enhance your gaming experience. Game preferences remain on your device. Player IDs, submitted scores and, when signed in, authentication tokens are also used by our backend to provide rankings and account features.

7.1 What We Store Locally

• Player Identifier: A unique ID to track your game progress
• Game Settings: Your preferences for game modes, controls, and display options
• High Scores: Your personal best scores (stored locally, with successfully submitted scores also held on our servers)
• Game Statistics: Your gameplay data and performance metrics

7.2 Data Upload

Completed games with a positive score are submitted to our leaderboard. Google sign-in is optional. Signing in links the current guest player ID and its submitted scores to your account so they can be retrieved on other devices. A player ID can be linked to only one account.

7.3 Managing Local Data

You can clear your local game data at any time through your browser's storage settings or by clearing your browser data. This will remove all locally stored game information from your device, including the login session. It does not delete previously submitted scores or account records. You can sign in again to retrieve scores already linked to your account.

• Right to access your personal information
• Right to correct inaccurate information
• Right to delete your personal information
• Right to restrict processing of your information
• Right to data portability
• Right to object to processing

If you are a parent or guardian and believe your child has provided us with personal information, please contact us, and we will delete such information from our files.
