What Are Cookies Anyway?

Cookies are small text files that websites store on your device. Think of them as digital sticky notes that help websites remember things about you — like your preferences or whether you've visited before.

They can't access other files on your computer or install anything. They're just data snippets that sit in your browser's storage. Some expire when you close your browser, others stick around longer.

How We Use Tracking on Tylvendo

When you browse our courses or read about React Native development, we collect information about your visit. This helps us see which topics get the most attention and where people drop off.

We track things like page views, time spent reading, and which links you click. This data shows us what's working and what needs improvement. If everyone abandons a course page after ten seconds, we know something's wrong.

Types of Tracking We Do

Specific Cookies We Set

Session Management

These remember your login state if you're enrolled in courses. They expire when you close your browser. Without them, you'd have to log in on every page.

• tylv_session — Maintains your login session (expires after 2 hours)
• tylv_secure — Security token for form submissions (session only)
• tylv_lang — Remembers your language preference (30 days)

Analytics and Measurement

We use Google Analytics to track visitor behavior. It's probably the most common analytics tool on the web. The data helps us understand traffic patterns and course popularity.

• _ga — Distinguishes unique visitors (2 years)
• _gid — Distinguishes users and sessions (24 hours)
• _gat — Throttles request rate (1 minute)

Marketing and Advertising

If you arrived through an ad, we track that to measure campaign effectiveness. This data tells us whether our ad spending actually brings interested people to the site.

• tylv_source — Records where you came from (7 days)
• tylv_campaign — Tracks which marketing campaign (30 days)

Managing Cookies Through Your Browser

Every browser lets you control cookies. You can block them entirely, delete existing ones, or approve them case-by-case. The downside? Some features won't work if you block everything.

Most browsers also have a "private" or "incognito" mode that doesn't save cookies after you close the window. That's useful if you're on a shared computer.

Third-Party Tracking

We embed content from other services sometimes — like videos or social media posts. These third parties might set their own cookies, which we don't control.

Services We Embed

• YouTube — For tutorial videos embedded in course materials
• Google Fonts — For typography (they might log basic metrics)
• CDN Providers — For faster content delivery worldwide

Each service has its own privacy policy. We can't speak for what they track, but we try to use privacy-focused options when available.

Your Rights and Choices

You're in control here. You can reject non-essential cookies using the button above, manage them through browser settings, or contact us to request deletion of any data we've collected about your visits.

If you're in the European Economic Area, you have additional rights under GDPR. You can access, correct, or delete personal data we hold. For cookie-related data, most of this is handled automatically through browser controls.

What Happens When You Reject Cookies

The site still works. You can read content, browse courses, and contact us. You just won't see personalized content recommendations, and we won't track your behavior across visits.

Some features might feel less smooth. For example, we can't remember your preferences between sessions, so you might see the same welcome message every time.

Changes to This Policy

We update this policy when we change how we use cookies. Major changes get announced on our homepage. Minor updates just show up here with a new date at the top.

We recommend checking back occasionally if you care about these details. Most people don't, and that's fine too.
