With iubenda, you only need to describe your website choosing which services collecting personal data your website uses. Remember that even a cookie is considered as personal data.
To understand the personal data collected on your website, just try to scroll the list of services by clicking on the “Add services” button. If you find something familiar, just click on the “add” button. Usually, examples of personal data collection are: collection for analytics purposes (e.g. to know how many visitors your website collects), collection for advertising purposes (banners and similar stuffs), email address collection for keeping your users up to date, registration form.
Iubenda may not cover some of the services you use. If this happens, just drop us a line at [email protected] asking us to fill the gap.
If none of the names of the services you read sounds familiar, try to ask for help to the web designer who built your website, or to the one who manages it.
