Cookie Policy

Last updated: April 2026

The short version

The main Cirdia website sets no cookies. A small number of dedicated marketing landing pages — only those under cirdia.com/l/*, reached from our social media ads — use the Meta pixel with your consent to measure ad performance. You can decline, and nothing else on our site tracks you.

Main site — no cookies

Every page on this website, except the marketing landing pages described below, sets no cookies on your device. No first-party cookies, no third-party cookies, no tracking cookies.

Analytics

We use Plausible Analytics across the site to understand how it's used. Plausible is privacy-first and cookieless by design — it does not use cookies, localStorage, or any persistent identifiers. It does not track you across sites or build a profile of your activity.

Page view data is aggregated and anonymous. No personal information is collected or stored by our analytics.

Session storage

If you arrive at our site via a link with UTM parameters (used to understand which marketing channels are working), we temporarily store those parameters in your browser's session storage. This is not a cookie — it clears automatically when you close the tab and is never shared with third parties.

Marketing landing pages (/l/*)

We run ads on Instagram and Facebook. When those ads lead to a dedicated landing page on our site (paths beginning with /l/), we need a way to measure whether the ad worked. For that, and only on those pages, we use the Meta pixel.

How it works:

  • When you land on one of these pages, a cookie banner appears. No tracking happens until you choose.
  • If you click Accept, the Meta pixel loads, sets its standard cookies (_fbp and sometimes _fbc), and sends a page-view event to Meta along with standard device/browser information.
  • If you click Decline, no pixel loads and no cookies are set. Your choice is remembered.
  • You can change your mind at any time by clicking Cookie preferences in the landing page footer.

What is shared with Meta: the fact that you visited a specific landing page, plus standard device/browser information the pixel sends by default. No health, wellness, symptom, wearable, or account data is ever shared with Meta. Our main site, app, and wearable devices do not use the pixel at all.

Our regular social media posts (not paid ads) link to normal pages on our site, which have no pixel. You only encounter the pixel if you arrive from one of our paid ads to a /l/ page and choose to accept.

Forms

When you submit a form on this site (such as becoming a partner or joining the alpha), the information you provide is sent directly to our servers. No cookies are set as part of this process.

Your rights

You have the right to decline cookies, to change your preferences at any time, and to ask us what data we hold about you. See our Privacy Policy for the full list of rights we extend to every user, regardless of jurisdiction.
