What cookies and localStorage do
Cookies are small values a website can ask a browser to store; matching cookies may be sent with later requests. localStorage is a separate browser mechanism that stores values for a site on your device. It is not automatically sent with each page request, although website scripts can read it.
These mechanisms can serve different purposes, including remembering preferences or supporting tracking. A storage mechanism’s name alone does not establish that its use is necessary or that it is exempt from consent requirements.
What the archive itself uses
The supplied archive pages and script do not set cookies, use localStorage or sessionStorage, or install analytics or advertising trackers. Navigation state, the selected hazard tab and contact-tool text are held in the current page. They are not deliberately saved by the archive after the page is closed or reloaded.
| Feature | Behaviour | Persistent site storage |
|---|---|---|
| Mobile navigation and hazard tabs | Temporary page state | None |
| Message Preview | Text assembled in the current page | None |
| Copy | Writes to your device clipboard when requested | Not a website cookie |
| Download | Creates a text file when requested | File remains until you remove it |
Your browser may independently cache page files, restore form entries or synchronise clipboard history. Those device features are not controlled by this archive’s script.
Publishing-system consent controls
A consent interface may be supplied separately by the system that publishes this site. Its own preference storage and any services it controls are separate from the archive features described above. Consult the information displayed by that interface for the relevant purpose, storage name, duration and available controls. This page does not claim a particular preference key or expiry period for an externally managed component.
Accepting a preference does not make the contact tool transmit a message. Essential-only choices do not prevent reading the static guides. Any optional services added to the published website should be disclosed and governed by the consent controls applicable to them.
Managing your device
You can inspect or remove a site’s cookies and storage in your browser’s privacy or site-data settings. Clearing data may reset preferences supplied by the publishing system. Use its preference controls, where available, to change your choice; deleting local data alone is not necessarily a withdrawal signal to a remote service.
Remove downloaded messages from your device and clear clipboard history separately if needed. Clearing website cookies does not normally delete those copies. Following a source link takes you to another site with its own storage practices.
