Introduction

DoubleSix is operated by MRX Software LLC ("we", "our", or "us"). This Privacy Policy explains what information we collect when you use the DoubleSix application and website (the "Service"), why we collect it, and the choices you have. We collect only what the Service needs to work — we do not sell your data, and we do not run advertising or third-party tracking on the Service today.

The Data We Collect

• Account Data. When you sign up, we collect your first name, last name, email address, and a password. Your password is never stored in plain text — we store only a salted, hashed version of it.
• Game Data. Score entries you record while using the Service are stored against your account so your game history is available across sessions.
• Technical Data. We log your IP address for security purposes, such as rate-limiting signups and detecting abuse of the Service.
• Cookies. We use a small number of cookies described in the "Cookies" section below.

We do not collect payment information or phone numbers.

How We Use Your Data

• To create and maintain your account.
• To verify your email address and authenticate you when you sign in.
• To provide the core scorekeeping functionality of the Service.
• To protect the Service and its users from fraud and abuse.
• To send you Service-related email, such as verification codes.

How We Share Your Data

We do not sell your personal data, and we do not share it with advertisers or data brokers. Your data is stored on infrastructure we operate directly. We may disclose information if required to do so by law, or to protect the rights, property, or safety of MRX Software LLC, our users, or the public.

Cookies

We use a cookie to remember your cookie consent preferences. If you sign in, we also use a cookie to keep you authenticated between visits. These cookies are necessary for the Service to function and cannot be disabled.

Our cookie banner also lets you opt in to "analytics" and "marketing" cookie categories. These categories are provided so you can set your preference in advance; as of the Last Updated date below, the Service does not actually load any analytics or advertising scripts, so no cookies are set for those categories. If that changes, we will update this Privacy Policy and the cookie banner accordingly.

Data Security

We use industry-standard measures to protect your data, including password hashing, encrypted connections, and access controls that limit who can reach production systems. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Data Retention

We retain your account and game data for as long as your account remains active. If you delete your account, we delete or anonymize your personal data within a reasonable time, except where we are required to retain it to comply with legal obligations, resolve disputes, or enforce our agreements.

Your Rights

Depending on where you live, you may have rights over your personal data, including the right to:

• Request access to the personal data we hold about you.
• Request correction of inaccurate personal data.
• Request deletion of your personal data.
• Object to or request restriction of how we process your personal data.
• Request a copy of your personal data in a portable format.
• Withdraw consent where we rely on consent to process your data.

To exercise any of these rights, contact us using the details below.

Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will post any changes on this page and update the "Last Updated" date below. Material changes will be communicated to you by email or through a notice in the Service.
