Cookie Notice

1. Introduction

This Cookie Notice explains how E2X ("we," "us," or "our") uses cookies and similar tracking technologies on e2x.ai (the "Service"). It describes what these technologies are, why we use them, and how you can control your preferences.

This Cookie Notice supplements our Privacy Policy — please read both documents to fully understand how E2X processes your information.

2. What Are Cookies?

Cookies are small text files that are placed on your device (computer, phone, or tablet) when you visit a website. They are widely used to make websites work efficiently, remember your preferences, and provide information to the site owners about how the site is being used.

In addition to cookies, we may use similar technologies such as local storage, session storage, and web beacons. For simplicity, this Cookie Notice refers to all of these collectively as "cookies".

3. Categories of Cookies We Use

We group the cookies on our Service into four categories based on their purpose:

3.1 Essential Cookies (Always Active)

These cookies are strictly necessary for the Service to function and cannot be turned off in our systems. They are usually only set in response to actions you take, such as signing in, setting your privacy preferences, or filling in forms.

• Authentication & session cookies — keep you signed in across pages (set by Clerk, our identity provider)
• Security cookies — protect against CSRF, abuse, and other security threats
• Load-balancing & routing cookies — ensure your requests reach the correct server
• Consent cookies — remember your cookie preferences so you don't have to set them on every visit

3.2 Analytics Cookies

These cookies help us understand how visitors interact with the Service by collecting aggregated, anonymous information such as page views, navigation patterns, and feature usage. We use this data to improve performance, reliability, and the developer experience.

Analytics cookies are optional. You can opt out at any time through our Cookie Settings link in the footer.

3.3 Preference Cookies

These cookies remember choices you make on the Service — for example, your dashboard layout, language, or model filters — so we can offer a more personalized experience. Disabling preference cookies will reset these choices on every visit.

3.4 Marketing & Third-Party Cookies

We do not use cookies for advertising or behavioural targeting. However, some third-party services integrated into our platform (such as embedded documentation or social media widgets) may set their own cookies when you interact with them. These are controlled by those third parties and not by E2X.

4. Third-Party Cookies

The following third-party services may set cookies when you use the Service. Each provider operates under its own privacy and cookie policy:

• Clerk — authentication, session management, and identity verification. Clerk Privacy Policy
• Stripe — payment processing, fraud prevention, and billing infrastructure. Stripe Cookie Policy
• Vercel — hosting, edge caching, and infrastructure analytics. Vercel Privacy Policy

We do not control these cookies. To manage them, please refer to the respective provider's documentation or your browser settings.

5. How We Use Cookies

We use cookies to:

• Keep you securely signed in across sessions
• Protect the Service against fraud, abuse, and security threats
• Remember your preferences (e.g. dashboard layout, model filters)
• Measure aggregate usage to improve features and reliability
• Provide essential functionality such as payment and billing

We do not use cookies to build advertising profiles, sell your data to advertisers, or track you across third-party websites.

6. Managing Your Cookie Preferences

You can manage cookies in two ways:

6.1 Through E2X

Open Cookie Settings from the footer to toggle optional cookie categories on or off. Essential cookies cannot be disabled because the Service relies on them to function. Your choices are stored locally on your device.

6.2 Through Your Browser

Most browsers allow you to view, manage, delete, and block cookies through their settings. Refer to your browser's documentation for instructions:

• Google Chrome
• Mozilla Firefox
• Apple Safari
• Microsoft Edge

Please note that disabling essential cookies may prevent you from signing in or using core features of the Service.

7. Do Not Track Signals

Some browsers offer a "Do Not Track" (DNT) signal that asks websites not to track you. Because there is no industry-wide standard for how to interpret DNT signals, our Service currently does not respond to them. Instead, you can manage your preferences through the Cookie Settings interface described above.

8. Changes to This Cookie Notice

We may update this Cookie Notice from time to time to reflect changes in our practices, technologies, or applicable law. When we make material changes we will revise the "Last updated" date at the top of this page and, where appropriate, notify you through the Service.
