Cookie Policy

Last updated: January 5, 2026

This Cookie Policy explains how OpenTrain AI (“OpenTrain,” “we,” “us,” or “our”) uses cookies and similar technologies on our websites and services (collectively, the “Platform”). It also explains the choices you have and how you can manage them.

This Cookie Policy should be read together with our Privacy Policy, which explains how we collect, use, and share personal information more broadly.

1. What cookies are

Cookies are small text files that a website places on your device (computer, phone, tablet) when you visit. Cookies help websites function, remember preferences, keep you signed in, and understand how people use the site.

Cookies are commonly described as:

• First-party cookies: set by OpenTrain (the site you are visiting).
• Third-party cookies: set by other companies whose tools or content are used on the Platform (for example, advertising or analytics providers).
• Session cookies: expire when you close your browser.
• Persistent cookies: remain on your device until they expire or you delete them.

2. Similar technologies we use

In addition to cookies, we and our service providers may use:

• Pixels (web beacons): small files or code that help measure whether you interacted with content (for example, visiting a page, clicking a link, or seeing an ad).
• Tags and scripts: code that enables site functionality, analytics, and advertising measurement.
• Local storage: browser storage used to remember settings or support site features (similar to cookies, but stored differently).
• SDKs (software development kits): commonly used in web and mobile experiences to support analytics or advertising functions.

For simplicity, we refer to all of these as “cookies” in this Policy.

3. Why we use cookies

We use cookies for the purposes below. Some cookies are essential to make the Platform work. Others help us improve performance, personalize your experience, and measure and improve our marketing.

A. Strictly necessary cookies (required)

These cookies are needed for the Platform to function and generally cannot be turned off in our systems. They are usually set in response to actions you take, such as:

• Maintaining your session and keeping you logged in (especially in authenticated areas of the Platform)
• Enabling core features like navigation, page load balancing, and form submissions
• Security, fraud prevention, and abuse detection
• Remembering your cookie consent choices (where required)

If you disable these cookies in your browser, parts of the Platform may not work.

B. Functional cookies (preferences and features)

These cookies help the Platform remember your choices and provide enhanced functionality, such as:

• Remembering preferences (for example, region, language, or other settings)
• Supporting embedded content or tools you choose to interact with

C. Performance and analytics cookies

These cookies help us understand how the Platform is used so we can improve it. They may collect information such as:

• Which pages are visited and how users navigate through the site
• Approximate location (derived from IP address), device and browser type
• Performance metrics (page load times, errors)
• Which features are used most often

We may also use cookies for testing and optimization (for example, measuring different versions of a page or feature to learn what works best).

D. Advertising and marketing cookies

We use advertising cookies to support and measure our marketing, including ads on platforms like Google and Meta (Facebook/Instagram). These cookies and pixels may be used to:

• Measure ad performance (for example, whether someone who clicked an ad later visited the site or created an account)
• Build audiences for remarketing (showing ads to people who previously visited our site)
• Limit how often you see the same ad (frequency capping)
• Help prevent fraud and improve ad safety

Advertising partners may use these technologies to collect information about your online activity over time and across different websites or apps.

4. Cookies set by platforms we use (Webflow, Bubble, and others)

Parts of our Platform may be built or hosted using tools such as Webflow (for marketing pages) and Bubble (for application functionality). These platforms may place cookies that are necessary for their infrastructure to work, such as cookies used for:

• Security and performance
• Session management and authentication (for logged-in areas)
• Load balancing and reliability
• Basic analytics or debugging

We may also use other embedded services (for example, review widgets, video players, customer support tools, or payment-related services). When these load, they may set cookies or similar technologies as described in this Policy.

5. How long cookies remain on your device

Cookie lifespans vary:

• Session cookies: deleted when you close your browser.
• Persistent cookies: remain until they expire or you delete them. Expiration can range from days to months (and sometimes longer) depending on the cookie and purpose.

6. Your choices and how to manage cookies

You have several options:

A. Cookie banner or preference tool (where available)

Depending on your location, you may see a cookie banner or preference tool that lets you accept or reject certain categories of cookies (for example, analytics or advertising cookies). You can also change your choices later if we provide a “Cookie Settings” link on the Platform.

B. Browser controls

Most browsers let you:

• See which cookies are set
• Delete cookies
• Block cookies (all cookies or only third-party cookies)
• Set rules for certain sites

If you block or delete cookies, you may need to reset preferences, and some features (especially login and account-related functions) may not work properly.

C. Advertising choices

You can also manage targeted advertising settings directly through providers (for example, Google and Meta) and through your device settings (for example, mobile advertising identifiers). Note that opting out of targeted advertising does not mean you will stop seeing ads. It means ads may be less relevant.

7. Targeted advertising and “sale” or “sharing” under some US state laws

We do not sell personal information for money.

However, using third-party advertising cookies and pixels (such as those used for measuring and improving advertising on Google and Meta) may involve sharing certain identifiers and online activity information with advertising partners. Under some US state privacy laws, this may be considered a “sale” or “sharing” of personal information for targeted advertising.

Where required, you can opt out by adjusting cookie preferences (if available) or using other controls described in this Cookie Policy and our Privacy Policy.

8. Do Not Track and similar signals

Some browsers offer “Do Not Track” signals. Because there is not a consistent industry standard for how to interpret these signals, the Platform may not respond to them.

Some jurisdictions also recognize signals like Global Privacy Control. Where required by applicable law, we will process recognized opt-out preference signals.

9. Changes to this Cookie Policy

We may update this Cookie Policy from time to time. If we make changes, we will update the “Last updated” date above. If changes are material, we may provide additional notice on the Platform.
