Privacy Policy for Sudokuheroes.com

Last Updated: August 20, 2025

Welcome to Sudokuheroes.com. Your privacy is critically important to us. This Privacy Policy document outlines the types of information that is collected and recorded by our website and how we use it. This policy applies only to our online activities and is valid for visitors to our website.

Information We Collect (And Why)

Sudokuheroes.com is designed to be a privacy-first experience. We do not collect any personally identifiable information (PII) such as your name, email address, or location.

The only data we "collect" is stored locally on your own web browser using a technology called Local Storage. This data is essential for the functionality of the game and remains on your device; it is never transmitted to our servers. This includes:

• Game State (sudokuGameState): This saves your current puzzle progress, including the numbers you've entered and the timer, so you can close the page and resume your game later.
• User Settings (sudokuSettings): This saves your preferences, such as your chosen theme (Light/Dark/Paper) and in-game settings (e.g., whether to highlight duplicates).
• Game Statistics (sudokuStats): This stores your win counts and best times for each difficulty level. This data helps you track your own performance.

You have full control over this data and can clear it at any time by clearing your browser's cache and site data.

Third-Party Services

We use a limited number of third-party services to enhance our website:

• Google Fonts: We use the Google Fonts library to provide the typography on our website. When you visit our site, your browser may send requests to Google's servers to fetch these font files. This may include your IP address. This is governed by Google's own privacy policy.
• Canvas Confetti: This is a JavaScript library used to create the celebration effect when you solve a puzzle. It runs entirely within your browser and does not collect or transmit any data.

Cookies and Local Storage

As mentioned, we use Local Storage instead of traditional cookies for core site functionality. Local Storage is a more modern and secure way to store data on your device without sending it across the internet with every page request. We do not use cookies for tracking or advertising purposes.

Your Data Rights

Since all functional data is stored on your own device, you are in complete control. You have the right to view, amend, or delete this data by using your browser's developer tools or by clearing your browser's site data for Sudokuheroes.com.

Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date. We advise you to review this page periodically for any changes.
