Do I need a cookie policy on my website?

Yes, if your website uses cookies. GDPR and most other privacy laws require that you disclose to visitors what information you collect from them, such as their personal data and what you do with this information. If you use cookies to collect data from your site users, then you must have a cookie policy. 

However, if your site already has a privacy policy page, it is not mandatory for you to add another page called ‘cookie policy.’ You can add the cookie details inside the privacy policy page in a separate section on cookies.
