Serenum does not collect any personal or non-personal information about you.
We originally worked on a feature that logged both private and non-private information about you. That feature would also give you - the visitor - complete control over your own data that we had stored in our database. But in the end, we removed it since we didn't found any real purpose for it other than for see how many people that visited Serenum.
The purpose with Serenum is to give you the current weather report and the forecast for 48 hours ahead and 7 days ahead at the same time your data are kept safe with you. We will never change that.
