Cookie Policy

What Are Cookies?
Cookies are small text files that are placed on your device (computer, smartphone, or tablet) when you visit a website. They are widely used to make websites work efficiently and to provide analytical and advertising information to website owners.
Cookies can be "session cookies" (deleted when you close your browser) or "persistent cookies" (stored on your device for a set period). They may be set by the website you are visiting ("first-party cookies") or by third-party services the website uses ("third-party cookies").
How Studylio Uses Cookies
Studylio itself uses minimal cookies — primarily for site hosting and basic session management via our hosting provider, Vercel. None of our own cookies are used to track your tool usage or store any content you enter.
However, we display advertisements through Google AdSense, which is a third-party service that places its own cookies on your device. These are used to serve personalised or contextual advertisements and to track ad performance.
