Privacy Policy

What happens while you play

Every card move, the current deal, your win/loss count and your best completion time are handled entirely inside your browser, using JavaScript. Nothing about which cards you have, which moves you make, or how a game ends is sent to a server, logged, or stored in any database on this site. There is no backend on this site capable of receiving that information, even if someone wanted it to.

This is a direct consequence of how the site is built: it is a static site with no game server. The board you see and the cards you move exist only in your browser's memory for the duration of that game.

What is saved on your device (localStorage)

The only things this site saves are stored in your browser's localStorage, on your own device: your light/dark theme preference, your draw mode (1 or 3 cards), your table and card-back customization, your best completion time, and your games played / games won count (used on the solitaire tips page to track whether your results are improving). None of this identifies you personally, none of it is sent to any server, and it only exists so the page can remember your preferences and progress on your next visit. You can clear it at any time by clearing this site's data in your browser settings.

The "share this deal" link

The Settings panel includes a Share this deal button. It builds a link containing the shuffle seed for your current deal, entirely computed in your browser, so that opening the link deals the identical sequence of cards. That link does not contain any personal information, only a number identifying the shuffle. Sharing it is optional and entirely up to you.

The feedback button

Below the board there is an optional thumbs-up / thumbs-down feedback button. Clicking it sends an anonymous signal (just the vote, no information that identifies you, no stored IP address, no tracking cookie) to this site's backend, purely so the count can be tallied. A local marker in your browser prevents you from being asked to vote again repeatedly, but that marker does not identify you personally, it only stops a second vote from the same browser.

Anonymous engagement measurement

This site measures a small set of anonymous, aggregate engagement signals so the tool itself can be improved: how quickly a visitor starts interacting with the page after it loads, whether the game was actually played (a game was won), whether a visitor left again within 10 seconds without interacting at all, and roughly how long a visitor stayed on the page (bucketed into ranges, not an exact duration). It also records a coarse category for where a visit came from (Google, Bing, a direct link, or "other"), never the full referring URL or any search terms.

None of this identifies you: there is no cookie, no session identifier, no stored IP address, and no browser fingerprinting anywhere in this measurement. Each page view is treated as a standalone, anonymous event sent once when you leave the page, using your browser's built-in sendBeacon mechanism to this site's own backend (not a third-party tracker). It cannot be linked back to a specific visitor, a specific device, or your game inputs.

Cookies

This site does not use advertising tracking cookies or third-party profiling cookies. The only local storage used is the localStorage mentioned above, for theme, game settings and progress, which is technically not a cookie and is not automatically sent to any server with every request, unlike a traditional cookie.

Hosting and infrastructure

This site is hosted on Cloudflare's network, which processes the technical requests needed to deliver the page to your browser (source IP address, browser type, request time), the same way any hosting provider does. That technical infrastructure data falls under Cloudflare's own privacy policy as the network operator, and is not accessed, exported or combined by this site to identify visitors individually. No hosting information is used for any purpose beyond delivering the pages and assets (CSS, JavaScript, card images) that make up the game.

What this site does not do

To be explicit rather than vague: there is no user account system, no login, no email newsletter signup, no advertising network, no remarketing pixel, and no sale or sharing of visitor data with data brokers. Playing free Klondike solitaire is the entire functionality of this site, and it does not require, request, or benefit from collecting personal information, so none is collected.

Changes to this policy

If the way this site collects or handles data changes in the future (for example, if a new feature required saving something on a server), this page will be updated to reflect that change before it takes effect. There is no fixed review schedule, but the commitment is to keep this text matching what the game actually does, not a generic description copied from elsewhere.
