Cookie Policy

Last updated:

We keep this short because we keep cookies short. aiArch always uses one strictly-necessary cookie to keep you logged in, and — only if you say yes — analytics cookies so we can see how the site is used, plus advertising-measurement cookies so we can tell which of our ads led to a sign-up.

The strictly-necessary cookie

We set a strictly-necessary, first-party authentication cookie, __session, through our authentication provider. It is set only after you log in, is marked Secure and SameSite=Lax, and has a lifetime of roughly seven days. Its only purpose is to keep you logged in as you move between pages. It is exempt from the consent requirement.

Analytics cookies (only with your consent)

If you accept analytics in the cookie banner, we load Microsoft Clarity and Google Analytics to understand how the site is used (which pages are read, where people get stuck). Each sets its own cookies and may aggregate measurement with its provider. Nothing is loaded and no analytics cookie is set until you accept — and you can change your mind at any time using .

Advertising-measurement cookies (only with your consent)

We run a small number of ads on Microsoft Bing. If you accept in the cookie banner, we load Microsoft Advertising's Universal Event Tracking so Microsoft can tell us which ads led to a sign-up. It sets the cookies below, and Microsoft may set its own MUID cookie on its domain. We send Microsoft a consent signal that defaults to "denied" — until you accept, the tag does not load and no advertising cookie is set. We use this strictly to measure our own ads; we run no third-party advertising on this site and do not sell personal data.

The cookie banner and your choice

On your first visit we show a cookie banner. Declining is as easy as accepting, and it is the default: until you accept, no analytics or advertising script loads and none of their cookies are set, so we rely only on the strictly-necessary cookie above. We remember your choice so we don't ask again (if we widen what consent covers, we ask again), and you can revisit it anytime with .

We show no third-party ads on this site, use advertising cookies only to measure our own ads, and do not sell personal data.
