Privacy Policy
Last Updated: 2024-12-08
Welcome to SudokuVariants ("we," "our," "us"). We are committed to protecting your privacy. This Privacy Policy outlines the types of information we collect, how we use it, and the measures we take to protect it.
1. Information We Collect
1.1 Logged-In Users
Cookies: When you log in to our website, we use cookies to identify you. These cookies are essential for the website's functionality, such as storing your user settings and keeping track of your progress on completed sudoku grids. Since we do not have advertisements and do not sell user information, we do not track users with cookies for any purpose other than these functional requirements. The cookies do not contain any personally identifiable information beyond what is necessary for these purposes.
Email Address Hash: For the purpose of logging in users, we store only a hashed version of your email address. We do not store your actual email address in our systems. The hash is used solely for authentication and account management purposes.
1.2 All Users
For all users we use strictly functional cookies.
Anonymous Data Collection: We collect certain anonymous information from all users, regardless of whether they are logged in or not. This information includes:
- ASN Number (Autonomous System Number): We collect the ASN number associated with your internet connection.
- Country: We determine and collect the country from which you are accessing our website.
- VPN/Data Center/Hosting Provider Information: We detect whether your IP address is associated with a VPN, data center, or hosting provider.
- User Agent and Version: We collect the user agent string and its version to identify the browser or application you are using to access our website.
- Operating System and Version: We collect information about your operating system and its version.
- Referrer: We collect the URL of the website or page that referred you to our site.
Please note: We do not store your actual IP address in our systems. The information we collect is used in an anonymized form to enhance our services and is not linked to any personally identifiable information.
2. How We Use the Information
Cookies: The cookies we use for logged-in users are strictly for functional purposes. They allow us to provide a personalized experience by remembering your settings and tracking your progress in interactive features such as sudoku grids. Since we do not display advertisements or sell user data, we have no need to track users beyond these necessary functionalities.
Anonymous Data: The anonymous data we collect helps us to understand our user base and enhance the performance, security, and functionality of our website. This data is analyzed in aggregate form to improve our services and ensure a better experience for all users.
Email Address Hash: The hashed email address is used solely for authentication purposes and to manage user accounts. Since we do not store your actual email address, the hash cannot be used to contact you or identify you beyond your login to our services.
3. How We Protect Your Information
We take the security of your data seriously. We use industry-standard security measures to protect the information collected on our website. While no system can be completely secure, we strive to protect your information from unauthorized access, disclosure, alteration, and destruction.
4. Sharing of Information
We do not share, sell, trade, or otherwise transfer any information we collect.
5. Your Rights
Cookies: You can choose to disable cookies through your browser settings. However, please note that disabling cookies may impact the functionality of our website, particularly for logged-in users.
Anonymous Data: Since the data we collect is anonymous and does not include your actual IP address, it cannot be traced back to you personally, and therefore, it does not fall under the same data access and correction rights as personally identifiable information.
Email Address Hash: Since we store only a hashed version of your email address, it is not possible to retrieve the original email address from our records. This ensures an additional layer of privacy and security for our users.
6. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically to stay informed about how we are protecting your information.
