Privacy policy
This policy explains the information handled by MyLuckyNumber's browser-based tools and the Google analytics and advertising services used on the main tool page.
Effective and last reviewed: July 15, 2026
Review status: this page is an implementation-based disclosure, not legal advice or a legal certification. The site owner must review it, including regional consent and advertising settings, before merge.
Summary
- Calculator inputs and generated results are processed in the visitor's browser by first-party JavaScript.
- MyLuckyNumber does not provide accounts and does not operate its own database of calculator inputs.
- The main tool page uses Google Analytics and Google AdSense, which may receive device, usage, cookie, and advertising information under Google's policies.
- Theme, language, history, favorites, statistics, and oracle history may be kept in the browser's local storage.
- The site's contact method is a public GitHub issue, so private or sensitive information should never be included.
Calculator inputs and first-party processing
Names, birth dates, phone numbers, plate text, pattern text, custom ranges, wheel entries, and other calculator inputs are handled locally by the site's JavaScript. The first-party application does not intentionally send these values to a MyLuckyNumber server. GitHub Pages delivers the static site files and, like other web hosts, may process ordinary request data such as an IP address, requested URL, time, and browser headers to deliver and protect the service.
This local-processing statement does not mean that visiting the page is anonymous. The analytics and advertising services described below can receive information about the visit, and anything submitted through an external link is governed by that service.
Information stored in the browser
The site uses localStorage, which remains on the device until the visitor clears site data, uses a browser mode that removes it, or the browser otherwise deletes it. Current keys include:
| Browser key | Purpose | Site limit |
|---|---|---|
luckynumbers_theme | Remembers light or dark theme preference. | One current value |
preferredLanguage | Remembers the chosen interface language. | One current value |
luckynumbers_history | Stores generated results, favorites, and data used for local history or statistics. | Up to 50 entries |
oracleHistory | Stores recent oracle cards for the local history view. | Up to 10 entries |
Storage can fail or be unavailable; the tools are designed to continue without persistent history where practical.
Google Analytics
The main tool page uses Google Analytics 4 with measurement ID G-BK1G1DX7PV to understand traffic and tool usage. According to Google, Analytics can collect information such as page and session activity, approximate geographic location, browser and device details, and identifiers used to distinguish visitors. When analytics storage is enabled, Google Analytics commonly uses cookies including _ga.
MyLuckyNumber uses aggregate reporting to understand whether the site works and which areas are used. Google controls how Analytics processes its data. See Google's Privacy Policy, Google Analytics data collection, and Google Analytics cookie usage.
Google AdSense and advertising
The main tool page uses Google AdSense publisher ID ca-pub-4935653668076079. Google and its advertising partners may use cookies, local storage, IP addresses, web beacons, device information, prior visits, and ad interactions to deliver, measure, limit, or personalize advertising, subject to user choices and applicable settings. Ads can link to third-party sites that MyLuckyNumber does not control.
Depending on region, browser signals, and configured Google controls, visitors may see a privacy or consent message and may receive personalized or non-personalized advertising. A non-personalized ad can still use limited technologies for purposes such as frequency capping, aggregated reporting, fraud prevention, and contextual selection. Google's eligible and commonly used providers are listed on its ad technology partners page; the partners used for a visit depend on publisher, region, and consent settings. See also How AdSense uses cookies and How Google uses information from sites that use its services.
Privacy choices
- Use any privacy choices shown in a Google message on the site. Availability and wording can vary by location and configuration.
- Review or change advertising personalization at Google's My Ad Center.
- Use the Google Analytics opt-out browser add-on where supported.
- Block or clear cookies and local storage in browser settings. Clearing local storage removes saved MyLuckyNumber preferences and history.
- Browser content blockers may prevent analytics or ads. Disabling JavaScript prevents most calculators from working.
External links and public GitHub contact
Links to lottery operators, support organizations, GitHub, Google, and other sites leave MyLuckyNumber. Those services set their own privacy and retention rules. A report submitted through the site's GitHub Issues contact method is public by default and can be copied, indexed, or retained by others. Do not post names, birth dates, phone numbers, account details, health information, or other sensitive data there.
Children and gambling-related content
MyLuckyNumber is an entertainment site and is not directed to children for gambling activity. It does not sell tickets or accept wagers. Visitors must meet the legal age and other rules that apply where they live before participating in any real-money game. See Responsible Play for safer-play guidance and support resources.
Changes to this policy
This page will be revised when relevant site code, hosting, analytics, advertising, contact methods, or retention behavior changes. The effective date at the top will be updated for a material revision. Repository history may show technical changes but does not replace the published policy.
Questions and corrections
Use the Contact page for a policy correction or implementation question. Because the available channel is public, describe the page or code behavior without including personal data. MyLuckyNumber currently provides no private email, account, deletion-request portal, or identity-verification process.
