Information Collection and Use

We don't require personal information to use the application. You will still be able to download decks, purchase credits and take quizzes without an account.

Kotoba Boost offers an option to create an account so that your quiz progress and credit purchases may be backed up for recovery as well as synchronizing across multiple devices. As mentioned above, this is completely voluntary. If you do choose this option, we us the Google OAuth 2.0 API service which will provide us with the email address of the primary account of your play store device. At no time do we share or use this email address for anything other than the usage of a unique identifier that proves your identity. At any time you may contact us from the email account we have to request your account be deleted.

Advertisements and Purchase systems are leveraged using Google APIs. With advertisements, the applications exculsively use the AdMob network. In the event of such features being necessary, the requests are handed off to these services. At no time do any of the application associate with personally-identifiable information or other identifiers to aid in advertisement practices. The advertisements are bound by the rules set forth by the Google API and AdMob systems of which the application has no control.
