This Privacy Policy explains how the website, Wix Store, membership features, and Mercurius Sudoku game operated under the online and operating name “TsukinoAiPlus” (collectively, the “Services”) collect, use, retain, and share information.

If you have any questions about this Privacy Policy or our handling of personal data, please contact us at tsukinoaiplus@gmail.com.

1. Information We May Collect

1.1 When You Visit the Website

When you browse the website, we and our service providers may automatically receive:

- Your IP address and approximate location;
- Browser, device, and operating system information;
- Pages viewed, referral source, visit duration, and basic interaction data;
- Information generated through cookies, pixels, device identifiers, and similar technologies;
- Security, abuse-prevention, and diagnostic information.

1.2 Wix Store, Orders, and Payments

When you purchase a product or use the Store, we may process:

- Your name, email address, and telephone number;
- Billing and delivery addresses;
- Products ordered, transaction amount, currency, order status, and transaction records;
- Delivery, return, refund, and customer service information;
- Order notes, messages, and other information that you voluntarily provide.

Payment information is generally processed directly by Wix and the selected payment service providers. We do not normally receive or retain full payment card numbers or card security codes. We may receive payment status, transaction identifiers, and limited payment-related information.

1.3 Membership Accounts and Communications

If you create a Wix membership account, sign in, submit a form, or contact us, we may process:

- Your account name, email address, and member identification information;
- Login activity, account status, and membership activity;
- Messages, questions, feedback, or other content that you submit;
- Communication subscriptions and preferences that you select.

Account authentication and passwords are generally handled by Wix.

1.4 Mercurius Sudoku

Mercurius Sudoku does not require users to create a game account. The following game information is primarily stored in the browser storage of the user’s device:

- Current game state, entered numbers, and notes;
- Available hints and hint usage;
- Language, theme, sound, and other game preferences;
- Completion times, personal records, and played puzzles;
- Locally generated or stored Sudoku puzzles;
- Daily Challenge date, difficulty, progress, and completion status.

This information is not currently synchronized between devices. Clearing browser data, using private browsing mode, uninstalling the PWA, or changing devices may permanently remove it.

The PWA version may also cache public program files and image resources on the device to support faster loading or limited offline use.

Mercurius Sudoku does not request access to precise location information, contacts, photos, the microphone, or the camera.

1.5 Advertising and Analytics

If Google AdSense is enabled, Google and its advertising technology partners may, subject to your consent choices, use cookies, local storage, IP addresses, device identifiers, and browsing information to:

- Provide personalized or non-personalized advertisements;
- Limit how often advertisements are displayed;
- Measure advertising performance;
- Prevent invalid traffic, fraud, and abuse;
- Produce aggregated reports.

The website may also use Wix Analytics. Google Analytics will process additional website usage information only if a separate Google Analytics integration is enabled.

If rewarded advertising is introduced in the future, the advertising provider may also process advertisement loading, impression, completion, and reward-delivery events. We will update the relevant disclosures before enabling this feature.

2. How We Use Information

Depending on the circumstances, we may process information to perform a contract, comply with legal obligations, pursue legitimate interests, or act with your consent. Purposes may include:

- Providing the website, Store, membership features, and game;
- Processing orders, payments, deliveries, returns, and refunds;
- Responding to enquiries and providing customer support;
- Saving game progress and preferences;
- Maintaining website security and preventing fraud;
- Analyzing service performance and resolving technical problems;
- Providing analytics, marketing, or advertising after obtaining any required consent;
- Complying with accounting, taxation, consumer protection, and other legal obligations;
- Establishing, exercising, or defending legal rights.

3. How Information May Be Shared

We share information only as reasonably required to operate the Services or comply with legal obligations. Recipients may include:

- Legal, accounting, regulatory, or law-enforcement authorities;
- External websites that you choose to visit, such as Patreon, Instagram, YouTube, or X.

External websites have their own privacy policies. Once you leave our website, their handling of information is governed by their respective policies.

We do not sell personal information in exchange for direct monetary payment. Certain personalized advertising activities may be considered a “sale,” “sharing,” or “targeted advertising” under some United States state privacy laws. Eligible users may opt out through the available privacy settings.

4. International Data Processing

Wix, Google, and other service providers may process information in countries or regions outside your place of residence. The data protection laws in those locations may differ from those in your jurisdiction. Service providers process information according to their applicable terms and legal safeguards.

5. Data Retention

We retain information only for as long as reasonably necessary for the purposes described above. For example:

- Order, payment, tax, and accounting records may be retained as required by applicable law;
- Membership and contact information may be retained until the account is deleted, deletion is requested, or the information is no longer required;
- Customer service records may be retained until the enquiry and a reasonable follow-up period have ended;
- Mercurius game information remains on the user’s device until it is cleared;
- Cookies and analytics information are retained according to the relevant cookie settings and service-provider retention periods.

Some information may need to be retained for longer where required by law or in connection with a dispute, refund, fraud investigation, or legal claim.

6. Your Rights

Depending on the laws that apply to you, you may have the right to:

- Request access to a copy of your personal data;
- Correct inaccurate information;
- Request deletion of information;
- Restrict or object to certain processing;
- Withdraw consent;
- Request data portability;
- Opt out of the sale or sharing of personal information or targeted advertising;

To exercise your rights, contact tsukinoaiplus@gmail.com. We may request reasonable information to verify your identity. Certain information may not be deleted immediately where it is needed to fulfil an order, comply with a legal obligation, or establish legal rights.

Mercurius users may also remove locally stored game information through their browser’s “clear site data” controls.

7. Cookies and Consent Settings

We use cookies, local storage, and similar technologies. Please refer to our Cookie and Advertising Policy for further details.

Where applicable, you may accept, reject, or manage non-essential technologies through the cookie consent banner. You may subsequently change your choices through the website’s “Privacy and Cookie Settings” control.

8. Children’s Privacy

The Services are not directed primarily at children under 13, and we do not knowingly collect personal information from children under 13. If you believe that a child has provided personal information without appropriate parental or guardian consent, please contact us.

A parent or guardian should provide appropriate supervision and consent before a child makes an online purchase.

9. Data Security

We and our service providers use reasonable technical and organizational measures to protect information. However, no method of transmission over the internet or electronic storage can be guaranteed to be completely secure.

10. Changes to This Policy

We may update this Privacy Policy when our Services, service providers, or legal obligations change. The revised version will be published on this page with an updated “Last updated” date. Material changes may also be communicated through an additional website notice.
