Privacy Policy

Operator

The service is operated by webpowers UG (haftungsbeschränkt). The authoritative provider and contact information is available in the official imprint.

Essential game data

The game stores settings, local progress and your privacy choice in your browser. This is required to retain those choices and does not require an account. You can remove local data through your browser settings.

Accounts, saved progress and leaderboards

If you voluntarily sign in or submit a score, the authentication and leaderboard features use Firebase services. The public leaderboard may display the submitted display name and game result. Playing without an account remains possible.

When you sign in, your progress, game statistics, favorite game, recent game activity and saved Solitaire, Spider, FreeCell, Sudoku and Nonograms games are backed up in a private Firebase account record so you can continue on another device. A current Minesweeper board is not saved for resuming. Detailed Minesweeper click histories stay on your device. Account records are accessible only to the signed-in owner; submitted leaderboard results are public.

Signing out switches back to separate guest storage on this browser; it does not delete your account backup. Clearing browser data removes local copies, while signed-in progress can be restored from your account. Contact the operator below for account-data requests.

Optional services

In the EEA, the UK and Switzerland, and when your region cannot be determined, Vercel Analytics and Speed Insights remain disabled until you select “Allow optional services”. Elsewhere these services are enabled by default unless you decline them. Selecting “Essential only” disables optional services; Privacy settings in the footer lets you change your choice at any time.

Your choice is saved in browser storage, with a session-only fallback if persistent storage is unavailable. Withdrawing permission removes the optional return-visit marker described below. The page reloads after a saved withdrawal so previously loaded optional scripts no longer run on the new page. Essential game progress remains available.

Gameplay and return-visit measurement

When optional analytics is enabled, Vercel receives gameplay events such as game starts, completions, active play time and game recommendations. Game run identifiers, account IDs and email addresses are not included in these events. Active play time excludes time while the page is hidden or you have been inactive for more than one minute.

To understand whether players return after 7 or 28 days, we store the first measured play date and the last reported play date in this browser. On a day when you make a real game move, we send at most one return-visit event containing that first date and the number of days since it, through day 28. Dates use UTC. No account identifier, stable visitor token or fingerprint is added to this event, and this browser marker is not synced to Firebase.

These reports describe participating browsers, not individual people or activity across devices. Clearing storage or withdrawing permission resets this measurement; blocked analytics and unavailable storage can leave gaps. We do not use it to identify you or infer your activity in another browser.

Advertising

Advertising is currently disabled for the EEA, the UK, Switzerland and unknown regions until a certified consent-management integration is configured and verified. Our optional-services choice is not represented as a certified advertising consent signal. In other regions, Google AdSense may load when advertising is allowed by your privacy choice.

If optional analytics is also enabled, we measure ad-request and availability states to check whether placements work. A requested or filled placement is not treated as proof of revenue. Rewarded ads are optional: an offer appears only when an ad is available, and a game reward is granted only after Google reports that the selected ad was viewed.
