Cookie Policy

This page lists every browser-storage item the site actually uses, verified directly in the codebase rather than assumed. There are no advertising or cross-site tracking technologies on this site.

Last updated 11 September 2026

Nothing on this page is legal advice. It describes our current position and documents in preparation; consult your own counsel for advice specific to your situation.

01What this policy covers

This policy describes cookies and comparable browser-storage technologies (such as localStorage) used on www.theosquantum.com. It does not cover data processed inside a customer's AutoPQC workspace, which is addressed in the Privacy Policy instead.

02The opt-in model

This site uses an opt-in model, not opt-out. Strictly necessary storage — the single item that records your cookie choice itself — is always on because the site cannot function sensibly without it. The one optional category, aggregate analytics, defaults to refused until you actively allow it.

If you dismiss the consent banner without making an explicit choice, or if you never see it because your browser blocks it, the optional analytics category remains refused. Refusal is the default state, not an exception you have to select.

03What is actually stored, item by item

The table below lists every item this site's own code writes to your browser, verified directly against the source that implements it, not inferred from a generic template.

Name	Category	Purpose	Storage mechanism	Duration	Party
theos.consent.v1	Strictly necessary	Records your cookie/analytics choice (accepted or refused) and the timestamp of that choice, so the banner does not reappear on every visit.	Browser localStorage (not a cookie)	Until you clear your browser storage or change your choice via Cookie settings	First party

The item above is not a cookie in the technical sense — it is a localStorage entry. We describe it here anyway because the practical effect on a visitor (something is remembered in your browser) is the same, and a cookie policy that only discussed literal cookies while ignoring localStorage would be misleading. An earlier version of the site also stored a light/dark theme preference; the site now renders in dark mode for everyone, nothing writes that item any more, and any residual copy of it in your browser is ignored.

04No advertising or cross-site tracking

This site does not run advertising pixels, retargeting tags, or cross-site tracking technologies of any kind. The one optional category described in the consent banner — aggregate analytics — is wired to Vercel, the platform this site is hosted on, and only for visitors who have actively allowed it.

The vendor, named. Vercel Web Analytics records page views and the pages they were on. Vercel Speed Insights records how quickly pages actually loaded and responded in your browser. Neither sets a cookie, neither stores an identifier in your browser, and neither follows you to any other site. Both scripts are served from this site's own domain, load only after you have allowed analytics, and stop loading the moment you withdraw that permission.

05Changing your choice

You can change your analytics choice at any time using the control below, which reopens the same preferences panel shown in the consent banner.

[PLACEHOLDER: confirm whether a persistent Cookie settings control will also be added to the site footer or header on every page; today the control shown above is on this page only.]

06What refusing costs you

Nothing. Refusing the optional analytics category does not disable any page, feature, form, or download on this site. The only storage that cannot be turned off is the single item that remembers your choice, which exists to make the site usable rather than to track you.

07Changes to this policy

If the set of storage items this site uses changes — for example if an analytics tool is enabled — we will update the table above and the “last updated” date at the top of this page.
