Privacy Policy
Isometry ("we," "us," or "our") operates the website playisometry.com (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices you have. We built Isometry to be a clean, ad-free daily puzzle game, and we take your privacy seriously.
1. Information We Collect
Guest players (no account required)
If you play without creating an account, we store your puzzle progress, solve history, and streak count in your browser's localStorage. This data never leaves your device and is not accessible to us.
Registered users (optional account)
If you choose to create an account, we collect:
- Email address — used to identify your account and send password reset emails if needed
- Display name — optional, chosen by you, shown on leaderboards (defaults to "Anonymous" if not set)
- Puzzle results — your solve history including date, difficulty, move count, and completion time
- Streak data — your consecutive daily play streak
- Account creation date
Analytics data (all visitors)
We use Google Analytics 4 to collect anonymized usage data to help us understand how players use the game and improve the experience. This includes:
- Pages visited and time spent on the site
- General geographic location (country and city, derived from IP address)
- Device type, browser, and operating system
- Traffic source (how you found the site — search, social media, direct link, etc.)
- In-game actions such as puzzles solved, difficulty selected, and share button usage
Google Analytics collects this data using cookies and may associate it with your Google account if you are signed into Google in your browser. You can opt out using the Google Analytics Opt-out Browser Add-on.
2. How We Use Your Information
- To create and maintain your account
- To save your puzzle solve history and streak across devices
- To display your display name on leaderboards (if you have set one)
- To send password reset emails when requested
- To understand how players use the game and improve features (via anonymized analytics)
- To measure the effectiveness of any future marketing efforts
We do not use your information for advertising, we do not sell your data to any third party, and we do not share your personal information with any third party except as described in this policy.
3. Cookies and Local Storage
localStorage (first-party)
We use browser localStorage to store your game state, theme preference, and session token if you are signed in. This data stays on your device and is not shared with third parties.
Analytics cookies (Google Analytics 4)
Google Analytics sets cookies to distinguish users and sessions and to measure how visitors interact with the site. The primary cookies are:
- _ga — distinguishes users, expires after 2 years
- _ga_XXXXXXXXXX — maintains session state, expires after 2 years
These cookies do not contain personally identifiable information. You can prevent them by using the Google Analytics Opt-out Add-on or by adjusting your browser's cookie settings.
Authentication session (Supabase)
If you create an account and sign in, Supabase Auth stores a session token in your browser's localStorage (not a cookie) to keep you signed in across sessions. This token is used only to authenticate your requests to our database.
4. Data Storage and Security
Registered user data is stored securely using Supabase, a hosted database platform. Data is encrypted in transit (TLS) and at rest. Authentication is handled by Supabase Auth, which follows industry-standard security practices.
Guest data is stored only in your browser's localStorage and is never transmitted to our servers.
Analytics data is processed and stored by Google in accordance with their data retention policies.
