Privacy note
Last updated: 2026-10-31
Chaoschemy games are playable without an account. Google sign-in is optional and is only used when you choose to manage an account. We do not read file contents.
Optional Google account
If you choose “Sign in with Google”, Google shares your stable account subject, verified email address, display name and profile image. Chaoschemy stores an internal user ID linked to that Google subject, a server-side session and the profile fields needed to show your signed-in state. We do not receive or store your Google password, and we do not request access to Drive, Gmail or contacts.
You can sign out or delete the Chaoschemy account from the sign-in control. Account deletion removes the stored account and sessions; anonymous game telemetry and local browser progress are not converted into account data automatically.
Rule bookmarks
Game rules you save are stored in your browser. They are not linked to your Google account or synced to another device.
Analytics
Cloudflare Web Analytics reports page views, device type, country or region and performance metrics so we can understand reach and improve loading. It is not used here for cross-site advertising profiles.
Google Analytics
We use Google Analytics 4 to measure page views and a few key actions: starting a game, finishing a game (won or lost) and getting an answer from a puzzle solver. Google Analytics sets first-party cookies (such as _ga) and receives basic page, device and browser information. We send the page address without its query parameters (only utm_ campaign tags are kept) and the referring page without its query; we do not send player input, puzzle boards, account details or form contents. Google signals and ad personalization are turned off for this property. Google Analytics is loaded only after the page has finished loading, is not added to Kids Game Garden, sign-in or checkout pages or to games embedded in another page, and is not loaded at all if your browser sends a Global Privacy Control signal. See the Google Privacy Policy and how Google uses information from sites that use its services. To opt out on every website, install the Google Analytics Opt-out Browser Add-on.
Besides Cloudflare Web Analytics and Google Analytics, we use our own first-party product events described under Game data, which use a random ID stored in your browser's local storage rather than a cookie.
Game data
Progress, daily challenge completion and sound preferences stay in your browser.
The site may send first-party product events such as a page view, game start, completion, restart, share click or Paddle checkout lifecycle event. These events include a random browser visitor ID and a short-lived local session ID so we can count returning browsers without asking for a name. They help us see which games people play and come back to. They do not contain a name, email, payment details, chat content or precise location. When a visit comes from another site, an event may include only that site's hostname as referrer_host; paths and query parameters are not stored, and internal navigation is not recorded as an external referrer. If the endpoint is unavailable, the event is not sent.
Payments
The games are free. Chaoschemy does not collect or store card details; if you make a paid purchase, the payment provider handles checkout and payment processing under its own privacy policy and terms.
Children's privacy
Kids Game Garden is made for families. Its games do not ask a child for a name, email address, photo or voice, and Google sign-in is not offered inside them.
Kids Game Garden progress stays in the browser on the device. The product events described above may also be sent from these pages, including the random browser visitor ID and local session ID. These identifiers allow us to recognize a returning browser; they do not identify a child's name.
If you believe a child has sent us personal information, or have a question about game data, email support@chaoschemy.com. We will help locate and delete the relevant data.
Advertising and cookies
Pages that carry ads show one Adsterra banner each, at the end of the page content: the puzzle solver pages and the Color Mixing Calculator (below the tool and its results, before the links to more solvers), the home page, the games directory and genre pages, each game's guide page (below the guide), the daily puzzle page, the tools directory, the strategy guides, the Marble Alchemy how-to guide and the Mix Anything recipe pages. The longer strategy guides and the Cauldron Drop, Potion Sort and Rune Unlock guide pages show a second banner partway down. Pages with an Adsterra banner do not load Google AdSense. Adsterra banners are not included on game play screens, the Halloween, Thanksgiving and Christmas game pages, children's pages, the 5 Letter Word Finder, About, Privacy, Terms, account or support pages, or in printed output.
Adsterra and its advertising partners may use cookies and process your IP address, browser and device details, and page information to deliver and measure ads. We do not pass your puzzle inputs, results or saved game data to the ad code. See the Adsterra Privacy Policy.
To stop Adsterra requests, open Ad choices beneath a banner and choose Turn off ads on this site. This browser stores your choice as chaoschemy:ads-consent and reloads the page without the ad code; Turn on reverses the choice. We also respect Global Privacy Control (GPC) and do not load Adsterra when that browser signal is enabled. You can block or delete cookies in your browser settings; turning off ads does not erase data an advertising provider has already received.
Chaoschemy may show ads served by Google AdSense after the site is approved, only on pages without an Adsterra banner. The same choices apply to AdSense: it is not loaded when Global Privacy Control is on or after you choose Turn off ads on this site. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet. Learn more about how Google uses information from sites that use its services.
You can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
Third-party links
Pages may link to GitHub, social networks, payment providers or advertising services after those services are configured. Their own privacy policies apply when you open them.
For questions or a deletion request, email support@chaoschemy.com.
