+Enhanced History Privacy Policy
+===============================
+
+This extension does not and will not [ever] send your data externally.
+
+If it does, then it's a bug, and not on purpose.
+
+Data may be stored locally (duh), but in that case it is fully yours to keep.
+
+No information about you is sent to us. That is the entire reason why this fork was created.
+
+I hope this appeases Google.
+
+Feel free to reach out if you have any questions.
