2. Your choices
The account page includes “Sign out & clear this device.” Browser controls can also remove site data. Clearing storage may sign the user out and erase local drafts or progress that has not synchronised.
These items are required to provide, secure or remember requested features, so there is no optional-cookie banner in the current version.
3. If optional technology is added
Optional analytics, advertising or similar technologies will remain off until this notice is updated and any required opt-in consent has been obtained. Silence, continued browsing and pre-ticked controls will not be treated as consent.
