 For details on how to import your data, have a look at the [importing wiki](https://github.com/pbogre/jetlog/wiki/Importing)
 
+## Privacy Notice
+
+Jetlog itself does not collect any user data outside of your own setup. However,
+it relies on external APIs ([adsbdb](https://www.adsbdb.com/)) for some features
+such as automatic flight fetching from the flight number. Since you cannot always
+be sure of how external APIs use your data, you may wish to opt out of these by setting
+the `ENABLE_EXTERNAL_APIS` environment variable to `false`.
