Privacy Policy

Block Master minimizes data collection. Game progress stays in local browser storage, there are no user accounts, and Google Analytics helps us understand aggregate use of the site.

Information stored on your device

The game uses browser local storage for the best score and may use it for current run preferences, daily completion, or practice progress as those features are enabled. The current implementation writes the blockmaster-best value. Local storage remains on your device and can be removed through browser site-data controls.

Block Master does not use local progress to create a public profile or leaderboard. Clearing browser storage may erase the saved value, and the project cannot recover it because there is no account copy.

Contact information

If you email luozhu2021@gmail.com, your email provider and the receiving mail service process your address, message, and any information you choose to include. Use the channel only for feedback, support, corrections, privacy questions, or rights concerns. Do not send sensitive personal data.

Messages may be retained as long as reasonably needed to answer the request, document a correction, address abuse, or meet legal obligations. Block Master does not sell contact messages or use them to build advertising profiles.

Google advertising and cookies

Block Master uses Google Ad Manager and may use Google AdSense to display advertisements. Google and its advertising partners may use cookies, including advertising cookies historically associated with the DoubleClick name, or similar technologies to serve and measure ads based on visits to this and other sites.

Third-party vendors, including Google, may place and read cookies on your browser or use web beacons and comparable technologies to collect information as a result of ad serving. Google may use that information for personalized advertising where allowed and consented, or for non-personalized and limited ads where required.

You can manage or opt out of personalized Google advertising through Google Ads Settings. You can learn how Google handles information on partner sites in the Google Privacy Policy and Google's advertising documentation. Browser settings can also block or delete cookies, although doing so may affect site functions.

Advertising status and publisher configuration

The site loads Google Publisher Tag for four manual Google Ad Manager units. The optional Google AdSense auto-ads script loads only when a valid NEXT_PUBLIC_ADSENSE_PUBLISHER_ID environment value is supplied. The AdSense publisher ID is not hard-coded in the app bundle; Google Ad Manager network and ad-unit paths are configured for the manual placements.

Manual units appear after or beside the primary product content, not inside gameplay controls or navigation. Each unit reserves a stable layout area, below-the-fold requests are lazy loaded, and mobile layouts exclude the 300×600 creative size.

Consent in applicable regions

Where law requires consent before advertising or analytics storage, the deployed site must show an appropriate consent mechanism before non-essential cookies are used. Choices should be as easy to decline as to accept and should be changeable later. This policy does not claim that an unconfigured local build has completed regional consent setup.

Analytics

Block Master uses Google Analytics 4 to measure aggregate visits, pages viewed, and basic interaction or technical information. Google may use cookies or similar technologies and process data such as device and browser information, approximate location derived from IP address, and usage events under its own privacy practices. We do not use Analytics to create site accounts or identify players by name.

The footer also loads the third-party Busuanzi counter to display aggregate site visitor and page-view totals. When it loads, request information is sent to that service to calculate the counter. The counter does not create a Block Master account.

Learn more in the Google Privacy Policy. Operational hosting providers may also process basic request data such as IP address, user agent, timestamps, and error logs to deliver and secure the site.

Children and sensitive data

Block Master is a general-audience puzzle and does not knowingly request information from children. The site has no accounts, chat, uploads, or payment forms. If you believe personal information was submitted inappropriately, use the Contact page.

Data sharing and legal requests

Information may be processed by hosting, email, security, and advertising providers only for their stated functions. It may also be disclosed when reasonably necessary to comply with law, protect users, investigate abuse, or defend project rights. Block Master does not sell personal information.

Your choices

You can clear local site data, manage browser cookies, adjust Google Ads Settings, avoid emailing personal details, and use available regional privacy rights. Contact the project for an access, correction, deletion, or objection request concerning information held through the contact channel.

Changes

Material changes will be reflected on this page with a new reviewed date. The policy must describe actual deployed behavior, so advertising, analytics, account, or upload features require an update before launch.
