Privacy Policy

Last updated: March 5, 2026

1. Introduction

Welcome to PlayBrain ("we", "our", "us"). This Privacy Policy explains how we collect, use, and protect your information when you visit playbrain.games (the "Site") and play our free online games. We are committed to protecting your privacy and being transparent about our data practices.

2. Information We Collect

We aim to collect as little data as possible. Here is what we may collect:

  • Game Data: High scores, game progress, and preferences are stored locally in your browser using localStorage. This data never leaves your device and is not transmitted to our servers.
  • Usage Data: We collect anonymous usage statistics such as pages visited, time spent on the site, browser type, device type, and referring URLs through Google Analytics. This data is aggregated and cannot identify you personally.
  • Game Play Analytics: We collect anonymous game play data (which games are played, engagement duration) using hashed, non-reversible identifiers. This helps us understand which games are popular and improve the platform.
  • Cookies: We and our third-party advertising partners (including Google AdSense) use cookies and similar tracking technologies to serve advertisements and analyze site traffic. See section 5 for full details.
  • Email Address: If you voluntarily subscribe to our newsletter or daily challenge emails, we store your email address. You can unsubscribe at any time.

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our games and services
  • Understand which games are popular and how players interact with them
  • Improve user experience and site performance
  • Serve advertisements via Google AdSense
  • Analyze site traffic and usage patterns via Google Analytics
  • Send email communications you have opted into (newsletters, daily challenges)
  • Respond to your inquiries and feedback

4. Legal Basis for Processing (GDPR)

  • Essential Cookies: Required for basic site functionality such as remembering your cookie consent preference. These cannot be disabled.
  • Analytics Cookies (Google Analytics): We use Google Analytics (measurement ID: G-WYVK2H638Q) to understand site traffic, page views, and user behavior. Google Analytics uses cookies to collect anonymous, aggregated data. You can opt out using the Google Analytics Opt-out Browser Add-on.

6. Data Storage and Retention

All game data (scores, progress, preferences) is stored locally on your device using your browser's localStorage. We do not store personal game data on our servers. You can clear this data at any time through your browser settings.

Anonymous analytics data is retained for up to 26 months in Google Analytics. Email subscriber data is retained until you unsubscribe. Game play analytics (anonymous, hashed) are retained indefinitely for statistical purposes.

  • Google AdSense ( Privacy Policy) for serving advertisements

Each of these services has its own privacy policy governing the data they collect. We encourage you to review their policies.
