Cookie Policy
Last Updated: July 30, 2026
Summary: onlinelabs.io uses a small number of cookies: essential ones that keep the site secure and working (Cloudflare, WordPress), analytics cookies that show us how visitors use the site (Google Analytics 4, Microsoft Clarity), and advertising measurement cookies for our own Google Ads and Meta (Facebook) campaigns. We do not run third-party ad networks and we do not sell data. You can block or delete cookies at any time in your browser settings; the site keeps working without the non-essential ones.
This Cookie Policy explains what cookies are, which cookies Online Labs ("we", "us") uses on onlinelabs.io, why we use them, and how you can control them. It complements our Privacy Policy, which describes how we handle personal data generally.
1. What Are Cookies?
Cookies are small text files that a website stores on your device when you visit. They let the site remember your visit, keep sessions secure, and measure how the site is used. Some cookies are deleted when you close your browser (session cookies), others stay for a set period (persistent cookies). Cookies set by the website you are visiting are "first-party" cookies; cookies set by other services embedded in the site (for example a YouTube video player) are "third-party" cookies.
2. How We Use Cookies
We use cookies for three purposes. Essential cookies keep the site online and secure: they power Cloudflare's bot protection, spam filtering on forms, and core WordPress functions. The site cannot work properly without them. Analytics cookies help us understand which pages people read, where visitors come from, and where the site can be improved; this data is aggregated and not used to identify you. Advertising measurement cookies let us see whether our own Google Ads and Meta campaigns lead to real inquiries, and power click-fraud protection (ClickCease) for those campaigns. We do not show third-party advertising on this site.

4. Third-Party Cookies
Cookies from Google, Meta, Microsoft, HubSpot, and YouTube are governed by those companies' own privacy policies: Google's cookie policy, Microsoft's privacy statement, HubSpot's cookie policy, Meta's privacy policy. YouTube videos on this site are embedded, and YouTube only sets cookies once you play a video.
5. How to Manage or Delete Cookies
You can view, block, and delete cookies in your browser settings: look for "Cookies and site data" in Chrome, "Enhanced Tracking Protection" in Firefox, or "Privacy" in Safari and Edge. Blocking essential cookies may break parts of the site (for example form submission), while blocking analytics and advertising cookies has no effect on your experience. For Google Analytics specifically, Google offers a browser opt-out add-on. Deleting cookies removes any previously stored identifiers from your device.
6. Changes to This Policy
We may update this Cookie Policy when our tools change. The "Last Updated" date at the top reflects the latest version. Significant changes will be visible on this page.
