Cookie Policy
This policy explains which cookies and local storage technologies CSV Stock Comparator uses, why we use them, and how you can control them.
1. What are cookies
Cookies are small text files that a website saves in your browser. They allow the site to remember your preferences, recognise you on your next visit, and understand how you use the application. In addition to cookies, we use localStorage — a similar mechanism that does not send data to the server but stores it exclusively in your browser.
2. Essential technologies (always active)
These technologies are necessary for the application to function. The legal basis for processing is legitimate interest (GDPR Art. 6(1)(f)) — without them the application cannot work properly. They cannot be disabled.
