Privacy & cookies
Last updated: 4 November 2026
This notice explains how information is handled when you visit zerocoins.io, play its browser games and use pages that include Google AdSense.
Game progress and browser storage
The games run in your browser. Game results, unfinished games, language, sound and game preferences are saved in local storage on your device. There is no player account or server-side game-save database. We do not intentionally send your saved game state to Google as part of the advertising integration.
You can remove these saves using your browser’s site-data settings. Doing so removes your progress and preferences. Private browsing or blocked storage may prevent saves from lasting between visits.
Google AdSense and advertising
The site includes Google AdSense code. Loading this code connects your browser to Google even if no advertisement is displayed. Google and its advertising partners may process information such as your IP address, browser and device information, pages visited, and interactions with advertisements. Cookies, local storage or similar identifiers may be used for advertising delivery, measurement, fraud prevention and, where permitted and consented to, personalised advertising.
Which advertising technologies are used depends on Google’s services, your choices, applicable requirements and whether advertisements are available. Non-personalised advertising can still use cookies or similar technologies; it does not necessarily mean that no information is processed.
Read how Google uses information from sites that use its services and Google’s Privacy Policy for information about Google’s processing, partners, retention and international data transfers. Google’s My Ad Center provides additional advertising preference controls.
Optional Google Analytics
If you choose to allow analytics, this site loads Google Analytics 4 (measurement ID G-CV4P6G03T7) to understand visits and game use. Google may process identifiers and technical information such as your IP address, browser, device, approximate location and referral origin. Analytics cookies can distinguish visits and returning visitors.
We send virtual page views and game events with a game identifier, play mode, whether a game was resumed, and aggregate results such as win/loss/draw, score, move and hint counts. Active-play estimates count foreground time after a gameplay action, stopping after inactivity. We do not intentionally send typed puzzle answers, full card layouts, saved-game contents, email addresses, or URL query strings to Analytics.
Analytics is optional and has a separate allow/decline choice from advertising. The Analytics tag is not loaded before you allow it. You can change your choice using Analytics choices in the game footer or the button below. Declining stops future analytics collection through this integration and attempts to remove accessible Google Analytics cookies. It does not delete data already processed by Google. No Google Signals or advertising personalisation features are enabled by this site's Analytics configuration.
The analytics choice is remembered in your browser. With analytics allowed, session storage also prevents duplicate game-start and completion events within the current tab. Clearing site data removes these preferences. Google's partner-sites notice and Analytics data safeguards explain more about its processing.
Consent and your choices
For visitors in the European Economic Area, the United Kingdom and Switzerland, advertising must respect the consent requirements that apply. Where a consent message is shown, use it to accept, reject or manage optional advertising purposes and vendors. You can use the message’s privacy-settings control, when available, to revisit your choices and withdraw consent. Withdrawal does not affect processing that was lawful before withdrawal.
You can also block or delete cookies and other site data in your browser. Browser controls are separate from the consent choices in an advertising message. Deleting site data may remove game saves and cause consent choices to be requested again.
Hosting and technical information
The site is hosted using Microsoft Azure Static Web Apps. Requests to deliver pages and assets involve technical information, including IP addresses and request details. Hosting and security providers may process this information to deliver the site, maintain reliability and protect against abuse. See Microsoft’s Privacy Statement.
Retention and your rights
Game saves remain in your browser until you delete them, the application replaces them or your browser removes them. Third-party advertising and hosting data are retained according to the relevant provider’s policies and settings; there is no single retention period for all of these services.
Depending on where you live and the processing involved, you may have rights to access, correct, erase or restrict use of personal data, object to processing, request portability, or withdraw consent. For data held by Google or Microsoft, their privacy policies describe the available request channels. You may also complain to your local data-protection authority; in Iceland, this is Persónuvernd.
