+### Privacy
+
+The meteroid app stores a few things permanently on your device
+("permanently" meaning, until you uninstall the app or clear its data):
+* the URL of your chosen mete instance
+* your user ID (just a number that identifies you)
+* your last five used items
+
+Additionally, some data may be cached temporarily:
+* your avatar
+* the avatars of other users
+* the images of drinks
+
+The rest of the data is kept in your mete instance. Please check its terms
+and make sure you trust its operators:
+* your chosen name (this can just be a nickname)
+* your e-mail address (optional)
+* your usage history (optional)
