Cookies are small text files that a website places on your device (computer, tablet, or mobile phone) when you visit. They are widely used by websites to make the site work, to function more efficiently, and to provide information to the owners of the site about how visitors use it.
Cookies are not programs — they cannot run code, deliver viruses, or damage your device. They are passive data storage files. A cookie can only be read by the server that set it, and it can only store the information you provide or that your browser provides when making a request. They are typically very small in size (a few hundred bytes to a few kilobytes).
There are different types of cookies based on how long they persist. Session cookies are temporary and are deleted when you close your browser. Persistent cookies remain on your device for a set period or until you delete them manually through your browser settings. Both types are used on metadxlab.org, as described below.
Some cookies are set by the website you are visiting (first-party cookies). Others are set by third parties that have content on the page you are viewing (third-party cookies). MetaDx Lab uses only first-party cookies and does not allow third-party advertising networks to place cookies on our site.
We use cookies for two primary purposes on metadxlab.org: to make the website work correctly (essential cookies), and to understand how visitors use the site so we can improve it (analytics cookies).
We do not use cookies for advertising. We do not use cookies to build profiles of individual users for commercial purposes. We do not share cookie data with advertisers or data brokers. If you accept analytics cookies, the data collected is used only to improve the website experience for veterinary professionals who use it.
These cookies are necessary for the website to function and cannot be disabled without breaking site functionality. They do not store any personally identifiable information and are set in response to actions you take on the site.
Cookie: metadx_cookie_consent
Type: localStorage item (functionally equivalent to a persistent cookie)
Duration: Stored until cleared by user
Purpose: Records your cookie consent choice (accepted or declined) so we do not show the cookie banner on subsequent visits. Contains only the string "accepted" or "declined".
Can be disabled: No — disabling this would cause the consent banner to reappear on every page load.
Session management cookies
Type: Session cookie
Duration: Deleted when you close your browser
Purpose: If you access the diagnostic portal (separate subdomain), session cookies maintain your authenticated session. These are set only after login and contain only an encrypted session identifier — no personal information is stored in the cookie itself.
Can be disabled: No — disabling session cookies would prevent you from staying logged in to the portal.
Analytics cookies help us understand how visitors interact with our website. The data collected is aggregated and does not identify individual visitors. Analytics cookies are only activated if you click "Accept" on our cookie consent banner. If you click "Decline", only essential cookies are set.
Analytics tracking
Type: Persistent cookie
Duration: Up to 12 months
Purpose: Tracks pages visited, time spent on each page, and general navigation paths through the site. This helps us understand which content is most useful to veterinarians, which pages have high exit rates, and where we should focus improvements.
Data collected: Page URLs visited, approximate geographic region (country level), browser type, operating system, session duration, and pages per session. IP addresses are anonymized before storage.
Can be disabled: Yes — select "Decline" on the cookie banner, or clear this cookie through your browser settings at any time.
MetaDx Lab does not use advertising cookies, retargeting cookies, or social media tracking cookies. We do not use cookies to track your activity across other websites. We do not sell cookie data or share it with advertising networks. We do not use fingerprinting or other non-cookie tracking techniques to identify individual users.
When you first visit metadxlab.org, you will see a cookie consent banner at the bottom of the page. This banner gives you the choice to accept or decline analytics cookies. The banner will appear on your first visit and will not reappear once you have made a selection, unless you clear your browser's localStorage or cookies.
Selecting "Accept" enables both essential and analytics cookies. Selecting "Decline" limits cookies to essential functionality only — the site will work correctly, but we will not collect analytics data about your visit.
You can change your preference at any time by clearing the "metadx_cookie_consent" item from your browser's localStorage (instructions below) or by clearing all cookies for metadxlab.org. After clearing, the consent banner will reappear on your next visit.
Clicking "Accept" or "Decline" does not require you to create an account or provide any personal information. The consent preference is stored locally in your browser and is not linked to your identity.
You have several options for controlling cookies on metadxlab.org and across the web:
All major browsers allow you to view, manage, and delete cookies through the browser's settings menu. You can typically find cookie controls under Privacy, Security, or History settings. Below are links to cookie management instructions for common browsers:
Google Chrome: Settings > Privacy and security > Cookies and other site data
Mozilla Firefox: Options > Privacy & Security > Cookies and Site Data
Safari: Preferences > Privacy > Manage Website Data
Microsoft Edge: Settings > Cookies and site permissions > Manage and delete cookies
Note that blocking all cookies in your browser will affect website functionality on many sites, not just metadxlab.org. Specifically, blocking essential cookies for our site will prevent you from logging in to the diagnostic portal and may cause the consent banner to reappear on every visit.
Our consent preference is stored in your browser's localStorage rather than as a traditional cookie file. To clear it manually, open your browser's developer tools (F12 in most browsers), navigate to Application > Local Storage > metadxlab.org, and delete the "metadx_cookie_consent" entry. After doing so, the consent banner will appear on your next visit.
If you previously accepted analytics cookies and wish to opt out, you can: clear the metadx_cookie_consent localStorage item (as described above) and select "Decline" when the banner reappears; or install a browser-level analytics opt-out extension; or contact us at privacy@metadxlab.org and we will assist with opting out of analytics tracking for your account.
The MetaDx Lab diagnostic portal (portal.metadxlab.org) operates on a separate subdomain and has its own session management. The portal uses session cookies to maintain authenticated sessions, CSRF protection tokens to prevent cross-site request forgery, and preference cookies to remember your report display settings. These are all essential cookies necessary for the portal to function securely.
If you use the diagnostic portal, you will receive a separate notice about portal-specific cookies when you log in for the first time.
We may update this Cookie Policy as our use of cookies changes or as legal requirements change. When we make changes, we will update the "Last updated" date at the top of this page. If we begin using new categories of cookies (such as adding analytics tools or changing providers), we will update this policy before implementing those changes and will reset consent preferences so that you see the consent banner again with updated information.
We encourage you to review this Cookie Policy periodically to stay informed about how we use cookies. If you have questions about our cookie practices that are not answered here, please contact us at privacy@metadxlab.org.
