We use tracking technologies on evolvstream.dev because they help us understand how people interact with our authentication systems documentation and learning materials. Cookies and similar tools let us remember your preferences, keep you logged into your account, and figure out which topics need better explanation.
This policy walks you through what tracking methods we use, why we need them, and how you can adjust settings if you want more control. We're pretty straightforward about what data we collect and what happens to it.
Cookies are small text files that get stored on your device when you visit our site. They contain bits of information that help the website recognize you on return visits. Some stay until you close your browser, while others hang around longer to remember your settings between sessions.
Besides cookies, we might use local storage, session storage, and pixels. These work differently but serve similar purposes - tracking how the site gets used and making your experience smoother. Local storage holds more data than cookies and doesn't expire automatically. Pixels are tiny images that load when you visit certain pages, helping us count visitors.
We categorize our tracking technologies into four groups based on what they do. Each serves different needs, and some are more critical to site function than others.
Essential Cookies
These are non-negotiable. The site won't work properly without them. They handle authentication, session management, and security features that protect your account and data.
- Keep you logged in as you navigate between pages
- Remember your authentication state
- Prevent security threats and unauthorized access
- Enable core site functionality
Functional Cookies
These remember your choices and make the site more personalized. You could disable them, but you'd lose convenience features that make learning easier.
- Save your language and region preferences
- Remember code editor themes you selected
- Store your progress through tutorials
- Keep track of completed lessons
Analytics Cookies
We use these to understand how visitors use the site. They tell us which pages get the most traffic, where people get stuck, and what content needs improvement.
- Count visitors and measure traffic sources
- Track which tutorials are most popular
- Identify confusing sections that need rewriting
- Measure how long people spend on different pages
Marketing Cookies
These track your activity across different websites to show you relevant content about our programs. They help us understand which marketing channels work best.
- Show you information about relevant courses
- Measure effectiveness of our outreach
- Connect with you about upcoming events
- Understand which topics interest you most
Session cookies disappear when you close your browser. Persistent cookies last longer - anywhere from a few days to a couple of years, depending on their purpose.
Essential authentication cookies typically last 30 days unless you log out manually. Preference cookies might stick around for up to a year so we don't ask you to set language preferences every visit. Analytics cookies usually expire after two years, though we often refresh them as you use the site.
You can clear all cookies manually through your browser settings whenever you want. Just know that doing so means you'll lose your saved preferences and need to log in again.
Managing Your Cookie Settings
Most browsers let you control cookies through their settings menu. You can block all cookies, accept only first-party cookies, or get prompted before any cookie gets set. Keep in mind that blocking essential cookies will break authentication features.
Each browser handles cookie management differently. Here are the common ones:
Chrome Settings
Firefox Options
Safari Preferences
Edge Settings
Third-Party Services
Some cookies on our site come from third-party services we use for analytics and learning management. These services have their own privacy policies that govern how they handle data.
We try to work only with services that respect user privacy and comply with international data protection standards. But you should know that when you interact with third-party content embedded on our pages, those companies might set their own cookies.
Updates to This Policy
We update this policy when we add new tracking technologies or change how we use existing ones. Major changes get announced through email to registered users. Minor clarifications just get updated here with a new date at the top.
We recommend checking back occasionally if you care about tracking details. The internet changes fast, and so do the tools we use to run educational platforms.
