Cookies are small text files that websites place on your device — whether it's your computer, smartphone, or tablet. Think of them as tiny notes that help websites remember who you are and what you prefer.
When you visit DevTools Universe, cookies help us keep you logged in, remember your preferences, and understand which tools you use most often. Without cookies, you'd have to log in every single time you visited.
Some cookies are placed by us directly (first-party cookies), while others come from services we use, like Google AdSense for advertising (third-party cookies). We're transparent about all of them.
Not all cookies are created equal. Here's a breakdown of each type we use on DevTools Universe:
These cookies are absolutely necessary for DevTools Universe to work properly. Without them, features like logging in and basic security would break.
Essential cookies cannot be disabled because doing so would make the website unusable.
Examples: Session IDs, authentication tokens, CSRF protection, secure login cookies
Functional cookies help us remember your preferences and settings so you don't have to set them up every time you visit.
Disabling them won't break the site, but your experience might be less convenient.
Examples: Theme preferences, language selection, recently used tools

DevTools Universe displays advertisements through Google AdSense to support our free tools and content. This helps us cover hosting costs and continue developing new tools for the community.
Google may show you ads based on your interests determined by your browsing activity across websites using Google services.
If you opt out, you'll still see ads — they just won't be tailored to your interests. They may be based on page content or general location.
