ReCAPTCHA by Google® service collects information that can be used by Google® to identify a visitor so as to determine if the actions on our site are actually human. So, the visitor’s IP address and other data that Google® needs for the reCAPTCHA service can be sent to Google. IP addresses within the member states of the EU or other parties to the Agreement on the European Economic Area are almost always truncated before the data ends up on a server in the United States. The IP address will not be combined with any other Google data unless you are logged in with your Google Account while using a reCAPTCHA service. First, the reCAPTCHA algorithm checks if your browser already has Google cookies from other Google services (YouTube, Gmail, etc.) and then reCAPTCHA sets an additional cookie through your browser to capture a snapshot of your browser window.
Cookies created by the reCAPTCHA service are third party cookies. On our effort to understand and record the information they collect we have created the following list of browser and user data. At any case, this list is not exhaustive and as this is a third-party cookie widely used on internet nowadays, we cannot guarantee that his Google® process is GDPR compliant.
- Referrer URL (the address of the page from which the visitor comes)
- Internet IP address (e.g., 2184.108.40.206)
- Information about the operating system (the software that enables you to operate your computer, known operating systems are Windows, Mac OS X or Linux)
- Cookies (small text files that store data in your browser)
- Mouse and keyboard behavior (any action you perform with the mouse or keyboard is saved)
- Date and language settings (which language or which date you have preset on your PC)
- Screen resolution (shows how many pixels the displayed image on your screen is made of)
It is indisputable that Google uses and analyzes this data before you click on the check mark “I am not a robot”. With the Invisible reCAPTCHA version you do not even tick the box anymore and the entire recognition process runs in the background. How much and what data Google® stores exactly, cannot be learned from Google® in detail.
Here we refer to the reCAPTCHA demo version of Google® at https://www.google.com/recaptcha/api2/demo. All these cookies require a unique identifier for tracking purposes.
Here is a list of cookies that Google® reCAPTCHA has set on this demo version:
