Cookie Policy · Quiz App

Overview

What are cookies?

Cookies are small text files placed on your device when you visit a website. They allow the app to remember things — like that you're logged in, which avatar you chose, or whether you've already seen this banner. Cookies cannot run code or carry viruses.

We also use similar technologies like localStorage and sessionStorage in your browser. These work the same way as cookies for the purposes of this policy.

      Your choice matters. Strictly necessary cookies are set automatically because the
      app cannot function without them. All other categories require your explicit consent and can be
      withdrawn at any time.

Third Parties

Third-party services

The app loads fonts and icons from Google Fonts and Cloudflare CDN. These services may set their own cookies. We have no control over third-party cookies — please review their policies directly.

      We do not currently use advertising networks, social media trackers, or any
      third-party analytics platforms (e.g. Google Analytics). If this changes, this policy will be
      updated and your consent will be sought again.
