Privacy note:
Google syncs your searches to the cloud. If the Book Library account is the only Google account signed in on your device, your device will report your search history under the BookFusion account.
We recommend signing in with a personal Google account, or creating one if you do not already have one. Alternatively, you may wish to consider changing your default search engine to an alternative, such as Bing, to ensure your private activity is not shared via the Book Library account.
