Sliding Block Master

EFFECTIVE DATE: April 13, 2026

This Privacy Policy serves to explain the methodologies employed by Hongtao Liu ("we", "our", or "us") regarding the collection, utilization, and safeguarding of your personal information when you engage with our iOS mobile application, Sliding Block Master. Our primary objective in gathering and processing your data is strictly to elevate the quality of our gaming products and to guarantee a seamless and enjoyable user experience for you.

1. Information Collection Practices

We leverage various techniques to collect, process, and handle your personal information, while maintaining a steadfast commitment to protecting your data security at all times. The subsequent sections outline the specific categories of personal data we acquire and our corresponding processing mechanisms.

1.1 Types of Personal Data Collected

When you download, access, or play Sliding Block Master, we may automatically collect the following standardized information about you:

Technical Log Data: Details such as your Internet Protocol (IP) address, the specific times you access the game, and the overarching category of your device.
Device Characteristics: Information including your device's brand and model, the installed operating system (specifically your iOS iteration), language configurations, and your local time zone.
Unique Identifiers: Digital tracking strings associated with your hardware, which may consist of the Advertising Identifier (IDFA), Google Ads Identifier, Google Device ID, Apple Game Center ID, and Google Play account credentials.
Game Interaction Metrics: Your ongoing progress within the game, achieved high scores, earned milestones, and logs detailing your social interactions with other players.
Transaction Information: Records of your purchase history, usage patterns, specific custom settings you have chosen, and data regarding any in-game virtual currency or items you acquire.

1.2 Supplementary Data Channels

If you decide to authenticate and log into the game utilizing third-party services, such as Apple Game Center, we will securely import relevant profile information from that service (which may include your chosen username and profile avatar). This action is performed strictly in accordance with the authorization guidelines set by the platform, and only after you have explicitly granted the requisite permissions via the third-party interface.

We strongly recommend that you familiarize yourself with the data processing habits of these third parties by reading their privacy guidelines:

Apple Game Center: https://www.apple.com/legal/internet-services/itunes/gamecenter/

By connecting to our game through a third-party login, you acknowledge and warrant that:

Your interaction with any game-related features strictly complies with the existing terms of service and regulations dictated by that specific third-party platform.
You meet the minimum age prerequisites defined by the third-party platform, in full compliance with the legal standards of your specific jurisdiction.

2. Purpose of Information Utilization

We deploy your collected data for the following specific purposes, ensuring that the processing of each personal data type is justified by the appropriate legal foundation:

Delivering and Supporting Services: To seamlessly process your in-game orders and requests, respond to your customer service queries, and facilitate ongoing communication; to provide the core gaming experience, personalize your gameplay, and transmit essential game notifications, technical updates, security alerts, and administrative support messages.
- Legal Justification: The processing activities outlined above are based on Article 6(1)(b) of the General Data Protection Regulation (GDPR) (commonly known as "performance of a contract"). This data handling is strictly necessary to fulfill the user agreement, keep the game operational, provide the services you request, and ensure the game receives vital maintenance.
Service Enhancement and Marketing: To deliver promotional updates about Hongtao Liu or carefully selected third-party offers that might pique your interest, contingent on your marketing preferences; to remember your customizable settings and tailor your gaming journey; to perform analytical reviews of usage trends, develop innovative new features, and broadly improve the overall caliber of our software, marketing campaigns, and customer support.
- Legal Justification: The aforementioned processing is founded on Article 6(1)(f) of the GDPR. We execute these data operations driven by our legitimate business interest in providing you with highly relevant content and continuously elevating the standards of our services.
Personalized Advertising: To broadcast customized advertisements, marketing campaigns, and relevant promotional content specifically to users who have provided consent to share their device's advertising identifiers with our network of advertising partners.
- Legal Justification: This processing is similarly grounded in Article 6(1)(f) of the GDPR. We undertake this processing based on our legitimate interest in showing you appealing advertisements and refining our overall service offerings.

3. Data Storage Duration

Your personal information is retained by us only for the period strictly necessary to provide our gaming services, fulfill our legal obligations, and/or to establish, exercise, or defend our legal rights. In scenarios involving dispute resolution, policy enforcement, game administration, or compliance with technical and legal requirements, we may archive a subset of your personal data for a reasonable and justified period.

Additionally, Usage Data is stored for internal analytical purposes. Generally, this Usage Data is retained for a notably short timeframe, except in instances where it is explicitly used to reinforce service security, improve technical functionality, or when statutory laws require an extended retention period.

4. Information Disclosure and Sharing

In accordance with your legal rights and relying upon the foundations of Article 6(1)(b), 6(1)(c), and 6(1)(f) of the GDPR, we may share or facilitate the disclosure of your information to various third-party entities under the following circumstances:

Authorized Third-Party Partners: For example, when jointly offering services, adhering to legal demands, addressing security concerns, during corporate transitions like mergers or asset sales, and in other specific situations where we have secured your explicit consent.
Legal and Regulatory Bodies: If we possess reasonable grounds to believe your actions violate our terms of service, or if disclosing the information is absolutely necessary to protect the rights, property, or personal safety of Hongtao Liu, our users, or the general public.
Other Game Users: For instance, when you actively participate in public leaderboards, community forums, or multiplayer events where your display data is inherently public.

4.1 Collaboration with Advertising Networks

Provided you have consented to data sharing in alignment with the applicable provisions of Article 6(1) of the GDPR, we will transmit your device's identification metrics to our advertising network partners to enable the display of tailored advertisements.

However, it is important to acknowledge that no method of data transmission across the Internet, nor any form of electronic digital storage, is completely infallible or 100% secure. Consequently, we cannot provide an absolute guarantee of total data security.

7. Device Push Notifications

If you have explicitly opted in to receive push notifications on your iOS device, we may occasionally send you alerts regarding game updates, significant news, service enhancements, and promotional offers. You possess complete control over these communications and can disable them at any time by navigating to your device's native notification settings.

8.1 Rights for Residents of the European Economic Area (EEA)

We are dedicated to handling and replying to your privacy-related requests promptly, generally within one calendar month of receipt.

The specific purposes behind our data processing;
The categories of personal data we are handling;
The identities or categories of third parties who have received or will receive your data;
The projected duration for which your data will be stored.
Furthermore, you are entitled to request a physical or digital copy of the personal data undergoing processing. Please be aware that this right of access may be legally constrained to safeguard trade secrets or intellectual property.

(2) The Right to Object

As per Article 21 of the GDPR, if we process your data based on legitimate interests (Article 6(1)(f)), you have the absolute right to object to this processing based on your unique circumstances. We are obligated to halt the processing unless we can present compelling, overriding legitimate grounds for the processing, or if the data is necessary for the defense of legal claims.

You may also object at any juncture to the utilization of your data for direct marketing purposes. Upon receiving such an objection, all marketing-related processing will cease immediately.

(3) The Right to Rectification

Under Article 18 of the GDPR, you have the right to request that we temporarily restrict the processing of your data under specific conditions. When restricted, we will only process your data with your explicit consent, for legal proceedings, to protect another individual's rights, or for reasons of vital public interest.

(5) The Right to Withdraw Consent

As outlined in Article 7 of the GDPR, if our processing relies on your prior consent, you retain the freedom to withdraw that consent at any given time.

Following withdrawal, we will cease all processing of the affected data, unless we are legally bound to retain it.
It is important to note that withdrawing consent does not invalidate the legality of any processing that occurred prior to your withdrawal.

(6) The Right to Data Portability

Per Article 20 of the GDPR, if the processing is automated and based on your consent or the performance of a contract, you have the right to request your personal data in a structured, widely-used, machine-readable format, and you have the right to transfer this data to a different service provider without hindrance.

(6) The Right to Request Deletion

You have the explicit right to request the permanent deletion of any personal data we have collected from you over the past 12 months.

Barring these specific exceptions, we will erase your information upon receiving a verifiable request.
