Cookie Policy
Last Updated: March 2025
DataDevix uses tracking technologies to improve your experience on our website. This policy explains what these technologies are, why we use them, and how you can control their use. We're committed to transparency about how we collect and use data when you visit datadevix.com.
What Are Cookies?
Cookies are small text files that websites place on your device when you visit them. They're pretty much everywhere on the internet these days. Your browser stores these files and sends them back to the website on subsequent visits, which helps the site remember things about you.
Think of them as digital sticky notes. When you visit a website, it might leave a note on your device saying "this person prefers dark mode" or "they're logged into their account." Next time you visit, the website reads that note and remembers your preferences.
These are cookies set directly by datadevix.com. We control them completely and they only work on our site. They help us understand how you interact with our courses and content.
These come from external services we use, like analytics providers or embedded content. They might track you across multiple websites, not just ours.
How We Use Tracking Technologies
We use several types of tracking technologies on our website. Each serves a different purpose, and some are more essential than others.
Essential Cookies
These are necessary for the website to function properly. They handle things like security, navigation, and basic functionality. Without these, parts of our site simply wouldn't work. You can't really disable these if you want to use the site.
Functional Cookies
These remember your preferences and choices. Things like your language preference, course filters you've applied, or whether you prefer list or grid view. They make your experience more personalized without tracking you for marketing purposes.
Analytics Cookies
We use these to understand how people use our website. Which pages do they visit most? Where do they get stuck? How long do they stay? This data helps us improve the site and create better content for our NLP programming courses.
Marketing Cookies
These track your activity to show you relevant ads and measure campaign effectiveness. If you've looked at our Python for NLP course, you might see related content elsewhere online. These are the ones people usually have the most questions about.
Specific Cookies We Use
Here's a breakdown of the actual cookies you'll encounter on datadevix.com. We try to keep this list current, but sometimes new tools get added as we improve the site.
| Cookie Name | Purpose | Duration |
|---|---|---|
| session_id | Maintains your session while browsing the site | Session |
| user_preferences | Stores your display and navigation preferences | 12 months |
| analytics_tracking | Helps us understand how visitors use the site | 24 months |
| course_progress | Remembers where you are in course materials | 6 months |
| marketing_consent | Records your marketing preferences | 12 months |
Other Tracking Technologies
Cookies aren't the only way websites track activity. We also use a few other methods that work similarly.
Web Beacons
Sometimes called pixel tags, these are tiny transparent images embedded in web pages or emails. They tell us when you've viewed a page or opened an email. We use them to see which email campaigns people actually read and which pages get the most attention.
Local Storage
This is similar to cookies but can store more data and doesn't expire as quickly. We use it to remember things like your course viewing history or draft forum posts you haven't submitted yet. It makes the site feel faster and more responsive.
Session Storage
Like local storage, but it clears when you close your browser tab. We use this for temporary things like keeping track of which sections you've expanded on a page during your current visit.
Why This Matters for NLP Learning
When you're working through our natural language processing courses, tracking helps us create a better learning experience. We can see which topics need more explanation, which examples resonate, and where people tend to get stuck. That feedback loop directly improves the education we provide.
Managing Your Cookie Preferences
You're in control of which cookies you accept. There are several ways to manage them, though some methods are more thorough than others.
Browser Settings
Every modern browser lets you control cookies. You can block them entirely, delete existing ones, or set rules about which sites can use them. Be aware that blocking all cookies will break some website functionality.
Mobile Devices
Both iOS and Android have privacy settings that limit tracking across apps and websites. Look for "Limit Ad Tracking" on iOS or "Opt out of Ads Personalization" on Android. These won't block all cookies, but they reduce tracking for advertising purposes.
What Happens When You Block Cookies
If you block cookies, you'll still be able to view most of our content. But you might need to log in every time you visit, your preferences won't be saved, and some interactive features might not work properly. It's a trade-off between privacy and convenience.
Data Retention
Different cookies stick around for different lengths of time. Session cookies disappear when you close your browser. Others might last for months or even years, depending on their purpose.
We regularly review and clean up old tracking data. Analytics information older than 26 months gets deleted. User preference cookies expire after 12 months of inactivity. If you delete your account, we remove all associated tracking data within 30 days.
Third-Party Services
We work with several external services that might set their own cookies when you use our site. These include:
- Analytics providers that help us understand website traffic and user behavior
- Video hosting platforms for our course tutorials and demonstrations
- Payment processors for secure transaction handling
- Email service providers for course communications
- Social media platforms if you interact with embedded content
Each of these services has its own privacy policy and cookie practices. We recommend reviewing their policies if you want to understand exactly what data they collect.
Updates to This Policy
This policy changes occasionally. Maybe we add a new analytics tool or stop using an old one. Perhaps privacy regulations change. When we make significant updates, we'll adjust the "Last Updated" date at the top of this page.
We won't notify you about minor clarifications or formatting changes. But if we start using cookies in substantially different ways, we'll let you know through an announcement on the website or via email if you're enrolled in courses.
Questions About Our Cookie Use?
