Cookies and consent
In the EU and UK, non-essential cookies (analytics, advertising) need consent before they are set, and your cookie policy must explain what each cookie is for. Strictly necessary cookies, like a login session, do not need consent but should still be listed.
Privacy-friendly analytics that set no cookies can remove the need for a banner for analytics; check each tool's documentation.
Questions
Do I need a cookie banner?
If you set non-essential cookies for EU or UK visitors, yes. The policy explains; the banner collects consent.
Is the list of cookies exact?
It lists typical cookies for each tool. Check your site's actual cookies in the browser's developer tools.
Is this legal advice?
No. It is a template to start from. Have a lawyer review it, especially if you handle sensitive data or sell in many countries.
Is what I type stored?
No. The document is built in your browser.
