Read the latest related update (Oct 2021): Matomo exempt from tracking consent in France
Cookie Consent in the data freedom law
It is necessary to inform users of the presence, purpose and duration of the cookies placed in their browsers, and the means at their disposal to oppose it.
What is a cookie?
Cookies are tracers placed on Internet users’ hard drives by the web hosts of the visited website. They allow the website to identify a single user across multiple visits with a unique identifier. Cookies may be used for various purposes: building up a shopping cart, storing a website’s language settings, or targeting advertising by monitoring the user’s web-browsing.
Which cookies are exempt from the Cookie Consent rule?
France has exempted certain cookies from the cookie consent rule: for those cookies that are strictly necessary to offer the service sought after by the user you do not need to ask consent to user. Examples of such cookies are:
- the shopping cart cookie,
- authentication cookies,
- short lived session cookies,
- load balancer cookies,
- certain first party analytics (such as Matomo (Piwik) cookies),
- persistent cookies for interface personalisation.
Asking users for consent for Analytics (tracking) Cookies
For all cookies that are not exempted from the Cookie Consent then you will need to:
- obtain consent from web users before placing or reading cookies and similar technologies,
- clearly inform web users of the different purposes for which the cookies and similar technologies will be used,
- propose a real choice to web users between accepting or refusing cookies and similar technologies.
You don’t need Cookie Consent with Matomo
The excellent news is that there is a way to bypass the Cookie Consent banner on your website:
If you are using another analytics solution other than Matomo then you will need to ask users for consent. If you do not want to ask for consent then download and install Matomo or signup to a service offering Matomo hosted in the Cloud to get started.
If you are already using Matomo you need to do two simple things: (1) anonymise visitor IP addresses (at least two bytes) and (2) include the opt-out iframe solution in your website (learn more).
Note that these recommendations currently only apply in France, but because the law is European we can expect similar findings in other European countries.
