This app is developed by the Privacy by Design principle.
We do not collect or store your personal data. Weerzien does collect some basic analytics and sends it to our own Matomo instance. This is not shared to anyone else. Again, no personal info is used, just analytics on how the app is used.
Weerzien does not consciously collect and/or share any other (meta)data to the developer (Touchinski) or other parties.
