Matomo still drops a cookie despite it is set to not use cookies

Support & Bugs

Im trying to avoid having to have a cookie banner at my site so Im disabling any cookie that is set, but Matomo still drops some cookies despite being disabled. I searched and found this:

https://matomo.org/faq/general/faq_157/#:~:text=It%20is%20important%20to%20note,increase%20user%20security%20and%20privacy.

It is important to note that even when cookies are disabled, Matomo may still set essential cookies in some cases, but these are purely functional and contain no personal data that would be covered by privacy laws. In fact, all of these cookies are actually designed to increase user security and privacy

GDPR doesn’t care about whether a cookie is essential or it ‘increases user security and privacy’. If cookies are being set, a cookie banner and consent are required.

Is it possible to prevent Matomo from dropping any cookie including functional or security ones so that a cookie banner wont be necessary?

Have a look at this:

Just note though with less cookies you’ll also have less data.

Also check here Cookies used by Matomo, you could tweak your config as such:

Thanks, I did see those but cant be sure whether that would fix my problem - Im using Matomo for Wordpress, I already disabled cookies, but it still sets a functional cookie.

In the 2nd link above it mentions this:

Certain configurations of Matomo may be used without consent for analytics purposes (refer to the ePrivacy and National Implementations guide)

Not sure if this answers your question that those functional cookies might not need consent. Maybe ask directly Matomo support about it as this is per their policies too.

There’s a lot of write-ups and interpretations in those pages, but afaik you have to show a cookie banner if you are setting functional cookies even if they don’t require consent:

This forum doesn’t let me add links to my post so I cant post the link. But this is what gdpr.eu says:

  • Strictly necessary cookies — These cookies are essential for you to browse the website and use its features, such as accessing secure areas of the site. Cookies that allow web shops to hold your items in your cart while you are shopping online are an example of strictly necessary cookies. These cookies will generally be first-party session cookies. While it is not required to obtain consent for these cookies, what they do and why they are necessary should be explained to the user.
