What Are Cookies

Cookies are small text files stored on your device when you visit a website. They help websites remember information about your visit, which can make your next visit easier and the site more useful to you.

Cookies We Use

Cookie Purpose Duration Type

Visitor Identification Cookie (ql_vid)

The ql_vid cookie is central to how qklnk works. When you click a qklnk short link, we assign a unique visitor ID (a random UUID) and store it in this cookie. This allows us to:

  • Track which links you clicked
  • Attribute conversions to the correct marketing source
  • Provide accurate analytics to link owners

This cookie is set on the root domain (e.g., .example.com) so it works across subdomains. It uses the SameSite=Lax attribute for security.

Session Cookies

When you log into qklnk, we use session cookies to keep you authenticated. These cookies are essential for the service to function and cannot be disabled while using the dashboard. They are automatically deleted when you log out or after 2 hours of inactivity.

Google Analytics

We use Google Analytics on our public marketing pages (like the homepage and pricing) to understand how visitors find and use our website. Google Analytics cookies are not used on authenticated dashboard pages. These cookies are set by Google and are subject to Google's Privacy Policy.

Managing Cookies

You can control cookies through your browser settings. Most browsers allow you to:

  • View and delete existing cookies
  • Block cookies from specific sites
  • Block all cookies (note: this may affect site functionality)
  • Use private/incognito mode to prevent cookie storage

If you block the ql_vid cookie, qklnk links will still redirect you to the destination, but click tracking and attribution may not work correctly.

For qklnk Customers

If you use qklnk to create short links, you are responsible for disclosing the use of tracking cookies in your own privacy and cookie policies. You should inform your users that clicking your links may set cookies for conversion tracking purposes.
