Personal data we collect about you and how we use it

a. Data collected from surfing the Website

When using our website, Decidim uses the services of Plausible analysis software. Its is software that, when tracking user data, this data is kept fully and securely encrypted. The purpose of Plausible Analytics is to track general traffic trends on your website and not individual visitors. Each HTTP request sends the IP address and user agent to the server, so that's what they use, generating an identifier that changes daily using the visitor's IP address and user agent. To anonymise this data, it is passed through a hash function with a rotating salt. This generates a random string of letters and numbers that is used to calculate the number of unique visitors for the day. The IP address of the raw data and the user agent are never stored in the logs, databases or anywhere on Plausible analytics disk. Older salts are deleted every 24 hours to avoid the possibility of linking visitor information from one day to the next. In this way, no personal user data is collected while browsing our website, for more information about the data processing by Plausible Analytics, you can visit their website at
