Privacy Policy

Who operates this site
Lumi Master at lumimaster.org is operated by achelie, an independent individual developer. For privacy questions or requests, email contact@lumimaster.org.
This policy covers this website and messages sent to its contact address. It does not cover the game, its publisher or services you use separately from this website.
Browsing and hosting
You do not need an account to browse this guide. The site does not offer purchases, collect game login credentials or request your device’s precise location.
Cloudflare hosts and delivers the website. To deliver pages and protect the service, network requests involve technical information such as an IP address, requested URL, request time and browser or device headers. Hosting and security processing is distinct from the aggregate analytics described below.
Site analytics
The site uses Ahrefs Web Analytics to understand visits and navigation, and Cloudflare Web Analytics to understand page performance. Requests can include the page visited, referral information and technical browser or performance measurements. These services help identify useful pages and loading problems.
Both providers describe their standard web analytics as cookie-free. This site does not use Google Analytics. Cookie-free analytics still involves sending requests to service providers; it does not mean that your browser makes no external requests. Hosting and these analytics services continue independently of your advertising preference.
Storage on your device
Your light, dark or system theme preference is saved in localStorage under lumi-dex:theme:v1. It remains in that browser until you change it or clear the site’s stored data.
Automatic Adsterra advertising follows the regional rules described below and your saved choices. The advertising preference uses lumi-dex:advertising:v2; older rejected choices under lumi-dex:advertising:v1 are preserved. A separate record under lumi-dex:adsterra-consent:v1 contains your explicit decision, policy version and the time of the choice. Automatically loading ads in a region does not create an accepted-consent record, and an old enabled preference is not consent. These records stay in your browser until you change or clear them. An older refusal is still respected. If storage is unavailable, an explicit choice may apply only to the current document or session; regions that require permission still need a valid choice on a new visit.
Closing the bottom banner stores a dismissal under lumi-dex:mobile-ad-dismissed:v1 in sessionStorage for the current tab’s browsing session. This closes that banner while other advertising remains enabled. Clearing site storage resets these preferences.
The dex uses sessionStorage keys beginning with lumi-dex:scroll: to remember your place when you return from an entry. This storage belongs to your browsing session and normally ends when you close its tab. It is not an advertising identifier.
Free search text is kept in page history or browser memory. The session key lumi-dex:search:v1 carries it across an internal full-page navigation and is consumed on arrival. It is removed from the visible URL before analytics and advertising scripts run. Restricted choices such as element, category, sorting and page number can remain in shareable URLs. An incoming request has already reached the hosting service before the browser can clean it, so do not put private information in URLs. Browser site-data controls clear these conveniences.
When you email us
Messages to the public contact address pass through Cloudflare Email Routing to a private Gmail inbox. Cloudflare and Google process the email to deliver and store it. The destination email address is not published on this website.
Your sender address, message, attachments and associated email metadata are used to review your request, investigate a correction or concern, and respond. Please send only information needed for that purpose. Correspondence is retained only as needed to handle the request and relevant security, rights or legal matters. You may request deletion of correspondence, subject to applicable obligations.
Advertising, cookies and your choices
Approval for Google AdSense is currently pending. The Google seller entry in our ads.txt file does not mean that Google ads are being displayed. This website does not currently load Google AdSense advertising scripts.
Our current advertising provider is Adsterra. Once permitted by the regional rules and your choices, content pages may load its native-ad, fixed-banner and Social Bar scripts. Fixed banners load within same-origin host frames; provider creatives may use additional frames. Social Bar may display notifications, widgets or interstitial overlays. Information pages, missing pages and initial loading or error screens do not load advertising.
A same-origin request uses Cloudflare’s IP-based country information and, for Canada, a province or territory code to apply our advertising rules. It does not request GPS access, return your IP address or city to the browser, or store your region in browser storage. Network routing and VPNs can affect this approximate location. The response is not cached across visitors, and no automatic ad request begins while the lookup is pending.
Our current prior-permission rules cover the EEA, the United Kingdom, Switzerland, relevant associated territories, Türkiye, South Korea, mainland China and Brazil. Québec also requires prior permission; Canada is treated the same way when its province or territory cannot be determined. Brazil’s inclusion is a precaution for third-party advertising profiles. If the location lookup fails or is unrecognized, we ask before loading ads. In other recognized regions, Adsterra ads can load automatically without a first-visit cookie panel, unless you have rejected or disabled them. These are rules for this advertising service, not a statement that every use of cookies elsewhere is exempt from local requirements.
During ad loading, display and interaction, Adsterra and its advertising partners may receive your IP address, page and referral information, browser or device details and advertising interactions. They may use cookies, web beacons or other identifiers to deliver, measure and personalize advertising. A sponsored-link destination has its own data practices.
If Google advertising begins after approval, third-party vendors, including Google, may also process these types of information. Advertising cookies can support selecting ads using activity on this website and other websites you have visited. Google and participating advertising companies may place or read cookies and use web beacons, IP addresses or other identifiers for delivery, measurement and permitted personalization.
Where prior permission is required, choose Allow cookies in the Cookies panel to start Adsterra advertising. Your valid saved permission allows these ads to load on later visits without asking again. In any region, Reject cookies, Withdraw consent or Disable ads stops automatic advertising. A supported browser Global Privacy Control signal also prevents automatic Adsterra advertising. Reopen in the footer at any time, including regions without a first-visit panel. This choice applies to Adsterra advertising, not hosting, site analytics or future Google advertising. Google consent controls will be available before Google advertising begins. Neither continuing to browse nor a regional default records advertising consent. The current Adsterra choices interface is not a Google-certified consent platform.
You can manage Google ad personalization through Google Ads Settings. Turning off personalization does not necessarily stop all advertising or cookie use. Provider details are available in the Adsterra privacy controls and policy.
Withdrawing Adsterra permission prevents new automatic ad requests and reloads a page if advertising has already started. It cannot reverse information previously sent, and does not disable hosting or analytics. Closing the bottom banner only dismisses that banner. Sponsored offer links remain optional external links; their destinations apply their own privacy practices.
Service providers and your choices
Information is processed by the providers described above for hosting, security, analytics and correspondence, and by advertising services when ads are enabled or you choose an external sponsored link. Providers may process information in countries other than your own under their applicable arrangements. The site does not sell mailing lists or use correspondence to build advertising audiences.
You can manage browser storage, restrict scripts using browser controls, and choose what to include in an email. Depending on the laws that apply to you, you may have rights to request access, correction, deletion or restriction of information held about you. Send requests to contact@lumimaster.org. We may ask for information reasonably needed to identify the relevant correspondence and verify the request; do not send identity documents unsolicited.
Children and policy updates
The guide does not ask visitors for their age or provide user accounts. Please do not send personal information about children. A parent or guardian who believes a child has sent personal information can contact us to request review and deletion where appropriate.
This page will be updated when the site’s data practices change. The date above identifies the latest revision. See About for the project’s purpose or Contact for help.
