What Are Cookies Anyway?

Cookies are small text files that get stored on your device when you visit a website. Think of them as digital sticky notes that help websites remember things about you — like whether you're logged in, what language you prefer, or items you've added to a cart.

They're not programs and can't carry viruses. But they do collect information, which is why we're telling you about them.

How They Actually Work

When you visit thinkultraflow.com, your browser receives these small files from our server. Your browser stores them and sends them back with each request you make to our site. This back-and-forth lets us recognize you between page visits.

Some cookies expire when you close your browser. Others stick around for weeks or months, depending on what they're designed to do.

The Types We Use

Why We Track This Stuff

Here's the honest truth: tracking helps us build better products. When we see that most visitors from Taiwan use mobile devices to access our AI application demos, we prioritize mobile optimization. When analytics show people leaving at a certain point, we investigate why.

For our education content, tracking tells us which learning programs get the most interest and which explanations confuse people. That data directly influences how we write and structure information.

Real Examples From Our Site

In late 2024, we noticed visitors spending significant time on our mobile AI documentation but rarely clicking through to related articles. That insight led us to redesign our navigation in early 2025, making connections between topics more obvious. Session duration on those pages increased by about 40%.

Another example: functional cookies remember if you've expanded certain sections of our technical documentation. Without them, you'd need to re-expand everything every time you reload the page. Small thing, but it matters when you're deep in learning mode.

Taking Control: Browser Settings

You have full control over cookies through your browser. Every major browser gives you options to block, delete, or manage them individually.

Keep in mind that blocking all cookies will affect how sites function. Some features might not work, and you'll need to log in every single time you visit.

Third-Party Cookies

We work with external services that set their own cookies. These include Google Analytics for traffic analysis, occasional advertising partners for marketing campaigns, and embedded content from platforms like YouTube if we include video tutorials.

These third parties have their own privacy policies. We choose partners carefully, but we can't control their practices once you leave our site or interact with their services.

When you decline non-essential cookies through our preference tool, we signal these third parties not to track you. But that depends on them honoring the signal. Browser-level blocking gives you more direct control.

Updates to This Policy

Technology changes. Our site evolves. Sometimes we add new features that require different tracking, or we switch to new analytics providers.

When we make meaningful changes to this policy, we'll update the date at the top and notify you through a banner on the site. For minor clarifications or corrections, we'll just update the document.

We recommend checking back occasionally if you care about the details. We won't make dramatic changes without letting you know.
