Last updated: February 12, 2026
This Cookie Policy explains how U2L.AI ("we", "us", "our") uses cookies and similar tracking technologies when you visit our website at u2l.ai and use our services. This policy should be read alongside our Privacy Policy.
1. What Are Cookies?
Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work efficiently, provide a better user experience, and supply information to website owners. Cookies can be "persistent" (remaining on your device until deleted or expired) or "session" cookies (deleted when you close your browser).
2. How We Use Cookies
We use cookies for the following purposes:
2.1 Essential Cookies
These cookies are strictly necessary for the website to function. Without them, core features would not work. They cannot be disabled.
| Cookie | Purpose | Duration |
|---|---|---|
| __session | Authentication session token (Firebase Auth) | Session |
| __cf_bm | Cloudflare bot management | 30 minutes |
| cf_clearance | Cloudflare security challenge clearance | Up to 1 year |
2.2 Preference Cookies

| locale | Stores your language preference | 1 year |
2.3 Analytics Cookies
We may use analytics cookies to understand how visitors interact with our website. These cookies collect information anonymously and help us improve the Service. We do not use third-party advertising cookies or trackers.
3. Third-Party Cookies
Some cookies on our website are set by third-party services that we use:
- Cloudflare: Sets security and performance cookies to protect against malicious traffic and optimize content delivery
- Firebase (Google): Sets authentication-related cookies for secure login functionality
- Payment processors: May set cookies during the checkout process for fraud prevention
These third parties have their own cookie and privacy policies. We encourage you to review them.
4. Link Click Tracking
When someone clicks a short link created through U2L.AI, we collect anonymous analytics data (country, device type, browser, referrer) to provide click statistics to the link creator. This tracking does not use cookies on the clicker's device. The data is collected from HTTP request headers during the redirect and no cookies are set on the visitor's browser.
5. Managing Your Cookie Preferences
You can control and manage cookies in several ways:
- Browser settings: Most browsers allow you to view, delete, and block cookies. Check your browser's help documentation for instructions.
- Device settings: Your mobile device may provide options to limit ad tracking or clear cookies.
- Opt-out tools: Some third-party services provide opt-out mechanisms on their websites.
Please note that disabling essential cookies may affect the functionality of the Service, including the ability to log in and use authenticated features.
6. Do Not Track Signals
Some browsers offer a "Do Not Track" (DNT) setting. There is currently no universal standard for how companies should respond to DNT signals. We do not currently respond to DNT signals, but we do not engage in cross-site tracking or sell your data to third parties.
7. Changes to This Policy
We may update this Cookie Policy from time to time to reflect changes in technology, legislation, or our business practices. We will post the updated policy on this page and update the "Last updated" date. Your continued use of the website after changes constitutes acceptance of the revised policy.
