Privacy Policy

Last Updated: May 21, 2026

Welcome to MahjongWander’s Privacy Policy (the “Policy”). This Privacy Policy explains how we collect, use, disclose, and protect information that identifies, relates to, describes, or can reasonably be linked to an individual or household (“Personal Information.”) It applies to your access and/or use of the MahjongWander Game found on our Website, MahjongWander.com, as well as your access and use of our Website, browser extension, and any other related services (collectively, the “Services”).

We know our users don’t love long and complicated policies, but it’s important for you to read them, so we’ve tried to make this as painless to read and follow as possible. By using the Services, you agree to this Policy. If you do not agree, please do not use the Services.

Any terms that are capitalized but not defined in this Policy have the meanings in our Terms of Service.

- Device identifiers (such as advertising ID or similar unique identifiers)
- Operating system and platform
- User agent and language settings
- Information about browser plugins and other technologies on your device

Usage and Analytics Data
Personal Information about how you access and use the Website, including:

We use cookies and similar tracking technologies (such as pixels, tags, and local storage) to collect and store this Personal Information.

Information Collected When You Play The Game:

In addition to the Personal Information collected automatically when you visit our Website, we collect certain Personal Information when you play the Game. This includes the following categories:

Login Data
If you choose to create an account or log in, we collect your login credentials, such as your username and password. Depending on the login method, this may also include your email address.

If you choose to log in using your email address, your login information and game progress may be stored locally on your device (for example, through cookies or similar technologies). This allows your progress to persist between sessions on the same device. Please note that if you clear your browser cache, cookies, or local storage, or if you switch devices or browsers, your saved login session and game progress may be lost.

If you choose to log in using a third-party account (such as Google, Facebook, or similar services), we may receive certain Personal Information from that third party, depending on your account settings and the permissions you grant. This may include your email address. We only use this Personal Information to authenticate your identity, create or link your account, and enable access to the Game. We do not receive or store your password for the third-party service. Your use of third-party login services is subject to their respective privacy policies and terms, and we encourage you to review them.

Gameplay and Game Data
We collect Personal Information about your interactions with the Game, including:

- Game progress, levels, and session activity
- In-game actions and events
- Performance data (such as scores or completion status)
- Error logs, crash reports, and diagnostic information

This Personal Information is primarily used to operate, maintain, and improve the Game, as well as troubleshoot technical issues.

Advertising and Tracking Data:

We collect Personal Information about your interactions with advertisements and marketing content in our Website, Game, and browser extension, including:

- Advertisements viewed (impressions)
- Advertisements clicked
- Actions taken after viewing an advertisement (such as installs or other conversions)
- The timing, frequency, and duration of ad interactions

We also collect and associate this Personal Information with identifiers such as your IP address, device information, user agent, and unique identifiers (including advertising IDs or similar technologies) that may recognize your device across sessions or over time.

We may combine advertising interaction data with other information we collect (such as gameplay and usage data) to create audience segments and infer your interests or preferences. These inferences may be used to deliver more relevant advertising and to support analytics and service improvement.

As a result, we may maintain persistent profiles associated with your device or browser over time. In some cases, our partners may also use this information, alone or in combination with information collected from other sources, to provide advertising and analytics services.

If you contact us for customer support, submit a request, or exercise your privacy rights, we collect the information necessary to respond and communicate with you. This may include:

- Your email address
- The contents of your communication
- Any additional information you choose to provide

We use this information to respond to your inquiry, verify your identity where required, and maintain records of requests in accordance with applicable law.

Inferences and Derived Data
We may generate or derive information about you based on the data we collect. This may include inferences about your preferences, interests, or patterns of behavior (for example, gameplay preferences or engagement patterns).

We use these inferences primarily to:
- Improve and personalize the Game experience
- Support analytics and performance optimization
- Deliver and measure advertising and marketing

These inferences may be linked to your device or account and may be maintained over time to better understand user behavior and improve our Services.

Sensitive Personal Information
We do not intentionally collect sensitive Personal Information such as Social Security numbers, biometric data, or financial account information. If you choose to provide such information to us, we will process it only as necessary to respond to your request or as otherwise permitted by applicable law.

Please note that if you block or disable all cookies, certain features of our Services may not function properly.

4. How We Share Information

We disclose Personal Information to third parties only as described below and consistent with applicable law:

1. With third party service providers, who assist us in operating, analyzing, or improving our Services. These include providers of data analysis, infrastructure, information technology, email delivery, and market-research. We share Personal Information with such providers only to the extent necessary for them to perform their contracted functions, and we require them to protect your information to at least the same level of privacy and security standards that we maintain. Service providers are prohibited from using Personal Information for any purpose other than providing technical assistance on our behalf and must notify us if they can no longer meet our data-protection expectations.

2. With your consent or at your direction, such as when you request or authorize a specific disclosure.

3. Law Enforcement, Compliance, and Protection. We may use or disclose Personal Information as we believe necessary or appropriate: (a) to comply with applicable laws, legal processes, or governmental requests; (b) to enforce our Terms of Service or other agreements; (c) to protect our operations, rights, privacy, safety, or property, or those of our employees, users, or others; (d) to assist in fraud detection, prevention, or investigation; (e) to pursue available remedies or limit potential damages or (f) to manage or resolve legal disputes or claims, including with persons authorized to act on your behalf in emergencies or events beyond our control, such as natural disasters.

4. In aggregated or de-identified form, which we may share with our partners, service providers, advertisers, and other third parties for business purposes, such as maintaining, improving, and securing our Services, or supporting related functionality.

5. With advertising or marketing partners, we may use third parties to deliver or measure marketing messages about our own products, and to enhance your experience with our Services, including by displaying advertising relevant to you. These providers may collect device identifiers and usage data to provide and measure advertising. We do not permit these partners to use your Personal Information for their independent advertising or marketing purposes. Users can manage ad preferences through their device settings. For more information about how we use cookies and other tracking technologies—and your choices—please see our Cookies and Tracking Technologies section.

6. In connection with mergers, acquisitions, or similar corporate transactions, including the sale, transfer, or reorganization of all or a portion of our business or assets. In such cases, Personal Information may be among the assets transferred, and we will take steps to ensure that any successor entity continues to handle your Personal Information in accordance with this Policy or provides you with notice and an opportunity to exercise your rights before any material changes take effect.

Any disclosures we make are limited to what is reasonably necessary for the purpose described and are subject to appropriate contractual or legal safeguards.

5. Data Security and Retention

We use commercially reasonable efforts to secure your Personal Information, but we cannot and do not assure that these measures will be sufficient to protect against all efforts to gain unauthorized access to the information.

Collected data is retained for only so long as needed to fulfill the purpose for which it was obtained, or as long as is reasonably necessary for our legitimate business purposes. We may retain your information for longer periods if required by law, or in relation to legal claims.

6. Children’s Data

Our Services are not directed to children as defined under applicable law. We do not knowingly collect, use, or process Personal Information from children.

If we become aware that we have collected Personal Information from a child in a manner inconsistent with applicable legal requirements, we will take appropriate steps to ensure that information is deleted as required by applicable law.

7. Your Privacy Rights

You have rights and choices regarding your Personal Information, which may vary depending on where you live. Your privacy rights may include the right to:

- Access – depending on applicable laws, request that we disclose the categories and specific pieces of Personal Information we collect, use, disclose, and share, as well as the business purposes for which we collect and use that information;

- Correction – request that we correct any Personal Information that is inaccurate or outdated;

- Deletion – request that we delete Personal Information we maintain about you, subject to applicable legal limitations;

- Portability – if it is reasonable under applicable laws for us to do so, request a copy of your data in a structured, machine-readable format and, in certain cases, ask that we transmit it to another data controller;

- Limit, restrict, object to, or opt out of processing or selling – under certain applicable laws, you may request that we stop or limit how we process your data, including limiting the use of sensitive Personal Information, and opt out of the selling or sharing of your Personal Information. Specifically, under California law, you also have the right to direct us not to “share” your Personal Information for targeted or cross-context behavioral advertising purposes at any time. In other U.S. states, similar opt-out rights may apply where our activities fall within the concept of a “sale” of Personal Information. Under certain applicable European laws, you may also request that processing be limited while we respond to one of your other requests; and

- Be free from discrimination for exercising your privacy rights.

If you have provided Personal Information based on consent, you may withdraw your consent at any time. We will consider and process your request within a reasonable time period as required by applicable law.

You can opt out of non-essential cookies and similar tracking technologies, including those used for targeted advertising, by using the “Your Privacy Choices” link in the footer of the Website you are visiting.

To exercise all other privacy rights please submit a request through the “Privacy Request Center” found through the “Your Privacy Choices” link in the footer of our Website.

Before processing or granting any request submitted through the Privacy Center, we will confirm that the right being exercised is available under applicable law, as certain rights may apply only to residents of specific jurisdictions. Only you—or a person authorized to act on your behalf—may submit a verifiable request related to your Personal Information. To ensure security, we verify your identity and confirm the Personal Information associated with you as permitted or required under applicable law. This may entail obtaining additional details depending on the type of request. We may use a third party verification service to assist in this process.

Depending on the jurisdiction, limitations may apply to how often access requests can be submitted within a 12-month period, and we may have the right to decline requests that are unfounded, excessive, or otherwise not considered reasonable within that jurisdiction’s standards. For example, under California law you may only make a verifiable consumer request for Access twice within a 12-month period.

If we deny your request, we will explain the reason and provide information about any rights to appeal. Please note that appeal rights may vary by state, and we may deny an appeal request if the laws of your state of residence do not provide a right to appeal.

We strive to respond within the timeframes required by applicable law.

If you wish to make a complaint about how we processed your request, please let us know. We take all complaints seriously and aim to resolve them with respect. Although we believe we can address most complaints with you directly, you may also choose to file a complaint with the relevant data protection authority.

8. Changes to This Policy

We may revise or update this Policy from time to time. If we make material changes to how we handle Personal Information, we will post changes to the Policy on our site and change the date on the top of this page. Your use of our Services following the posting of changes on our website will constitute your consent to the changes. If required by law we will provide additional notice in advance (e.g., a disclaimer on our website).
