No tracking theatre.
The current site uses only the storage needed to make the experience work and does not load audience analytics or advertising technology.

The practical answer
Spectra uses one session-storage preference to avoid replaying the homepage introduction. It does not currently set non-essential analytics or advertising cookies.
Current position
No advertising or audience analytics cookies.
Spectra does not currently load Google Analytics, Microsoft Clarity, advertising pixels or cross-site behavioural tracking. There is therefore no non-essential analytics consent banner in this release.
Essential storage
One session preference keeps the introduction from repeating.
The homepage uses session storage named spectra-intro-seen after the manufacturing sequence completes or is skipped. It expires when the browser session ends and is used only to avoid replaying the introduction on every visit.
- No worksheet values are stored by the site
- No advertising profile is created
- Cloudflare may use essential security cookies if it needs to defend the service
Future changes
New measurement requires a new decision.
If non-essential analytics or marketing technology is introduced, this notice, the privacy notice and a genuine consent control must be updated before it loads. Refusing optional measurement must not prevent access to the website.
