Privacy Policy

Introduction

Welcome to Sudoku Hot. We respect your privacy and are committed to handling information responsibly. This policy explains what data may be involved when you use our website, how we use it, and the choices you have.

Sudoku Hot is designed to work without a mandatory account. Most gameplay data stays on your device unless you choose to contact us or interact with third-party advertising and analytics services.

1. Who we are and what this covers

This policy applies to your use of the Sudoku Hot website and related browser-based features, including difficulty selection, daily challenges, statistics stored locally, display advertising, and the feedback form.

Please read it together with our Cookie Policy, Affiliate Disclosure, and Terms of Service for a complete picture of how the service operates.

2. Data we may collect or process

We aim to collect only what is needed to run the service. Because we do not require sign-in, we typically do not collect traditional account profile data unless you voluntarily send it through feedback.

• Device & technical data Browser type, language preference, theme choice, approximate location derived from IP address, referrer URL, and similar technical signals needed to render the site correctly.
• Gameplay & usage data Puzzle progress, daily challenge completion, difficulty preferences, and stats—primarily stored in your browser via localStorage.
• Contact data If you submit the feedback form, we may process the name, email, and message you provide solely to respond or improve the product.
• Advertising & analytics data Google Analytics, Google tag (gtag.js), Google Ads, and Google AdSense may collect pseudonymous identifiers, page views, ad interactions, device information, and cookie-based signals to measure traffic and deliver ads.

3. How we use information

We use information only for legitimate purposes such as:

• Operating and improving puzzles, performance, and accessibility.
• Remembering your preferences (theme, language) on your device.
• Measuring site traffic, campaign performance, and feature usage through Google Analytics and Google Ads.
• Serving and limiting display ads through Google AdSense and other advertising partners.
• Responding to feedback you send voluntarily.
• Complying with legal obligations where applicable.

4. Third-party services

Sudoku Hot uses third-party services that may process data on our behalf or as independent controllers, including Google Analytics, Google Ads conversion tracking, and Google AdSense. These providers may use cookies, pixels, and similar technologies as described in our Cookie Policy.

You can learn more about how Google uses data at policies.google.com/technologies/partner-sites. Where available, you may opt out of personalized advertising through your Google account settings or browser controls.

• Google Analytics / Google tag (gtag.js): traffic measurement and site usage insights.
• Google Ads: conversion tracking and remarketing related to our campaigns.
• Google AdSense: display advertising and ad performance measurement.
• Third-party ad partners: additional ad delivery and frequency capping through ad networks.

5. Data security & retention

We apply reasonable measures to protect information processed through our systems. Data stored locally in your browser is subject to your device security—clearing site data will remove it.

We do not sell your personal information. Advertising and analytics providers retain data according to their own policies and your browser or account settings. We will update this policy if we materially change the services we use.
