What a cookie is
A cookie is a small value that a website or its infrastructure can ask a browser to store and send with later requests. Cookies can support essential operation, remember preferences or enable measurement and advertising. Their purpose depends on the particular service setting them.
Storage used by these pages
The supplied HTML, stylesheet and script do not set cookies, read cookies, or use localStorage or sessionStorage. They do not include advertising tags, analytics libraries, third-party fonts or embedded audio and video players.
The mobile menu and reveal effects hold temporary state in the current page. They do not need persistent identifiers. Expandable exercise sections use the browser’s native disclosure controls.
Contact drafts, copying and downloads
The correspondence tool holds your typed text in the open page. Preparing a draft does not save it to website storage or send it to the publisher. Your browser may independently offer form restoration or autofill according to its settings.
When you choose to copy a message, the tool requests access to write that draft to your clipboard. When you choose a download, it creates a plain-text file on your device. Neither operation is a cookie. Clear your clipboard or remove the downloaded file through your device if you no longer want those copies.
Caching and hosting
Your browser may cache site files so they load more efficiently. A cache stores resources such as images, CSS and JavaScript and is different from an analytics identifier.
Hosting, delivery or security infrastructure can have behavior outside the page files, including technical logs or essential security cookies. The absence of cookie-setting code in these pages does not establish that every infrastructure layer is cookie-free. If you see an unexpected cookie, you can ask us to investigate its name and apparent source.
Your browser controls
Use your browser’s privacy settings to view and remove site data, block cookies or clear cached resources. The exact controls depend on the browser and device. Blocking cookies does not prevent the supplied exercise pages from being read. Disabling JavaScript removes the draft tool and animated enhancements, but the written guides, email link and expandable constraints remain available.
Clearing browser site data does not necessarily delete downloaded files or clear a system clipboard. Those are controlled separately by your device.
Changes and questions
If optional measurement, embedded services or other storage-dependent features are introduced, this notice should be updated and any required choices provided before those features operate. For questions about the current pages, email [email protected].
For information about email correspondence and technical requests, read Privacy. Conditions for using the exercises and message tool appear in Terms.
