What cookies are
A cookie is a small value that a website or service asks your browser to store and return with relevant requests. Cookies can support a necessary function, remember a preference or track activity, depending on how they are used. Their purpose matters more than their name.
LocalStorage and sessionStorage are separate browser mechanisms that scripts can use to retain values. They are not automatically sent with every request, but can still involve privacy considerations. Browser caching stores copies of files to reduce repeated downloads and is different from using a tracking identifier.
What the supplied pages use
The supplied HTML, CSS and JavaScript do not set cookies or write values to localStorage or sessionStorage. They do not include analytics, advertising trackers or third-party embedded content. Subject tabs, navigation menus and lesson accordions work without persistent storage.
The contact drafting tool holds text in the current page. Copying places text on your clipboard at your request; downloading creates a file on your device. Neither action is a cookie, and neither sends the draft to this website. Your browser may separately remember form entries or restore a previous page.
Hosting and separately added controls
A hosting or security service may use technical storage outside the supplied page code. A separately provided consent interface may also store a choice so it can remember it. Any such service should be described by its actual purpose, provider and duration when deployed; this page does not invent a cookie list for unconfigured services.
Optional storage or tracking should not begin before valid consent where the applicable law requires it. If a separate consent control is shown on the deployed website, use that control to manage the options it describes. Withdrawing consent should be as straightforward as giving it.
Managing your browser
Your browser’s privacy or site-data settings normally let you inspect, block or delete cookies and other stored website data. The steps vary between browsers and versions. Blocking all cookies can affect other websites even though these supplied lessons do not require them.
Clearing site data does not normally remove a downloaded text file, a sent email or content already copied to your clipboard. Manage those separately using your device’s file, email and clipboard controls. Private browsing also does not make an email anonymous or erase a file you deliberately save.
Questions about storage
Contact [email protected] if something about the site’s storage behavior is unclear. Include the page and browser involved, but do not send passwords or sensitive browser exports. The Privacy notice explains broader information handling, including email correspondence.
