Current status
Vocbook does not currently show third-party advertising in the app. The main monetization surface is Vocbook Pro, which may be offered through Google Play subscriptions and managed through RevenueCat.
Personalization
Vocbook does not sell vocabulary content or use your saved words, notes, images, pronunciation attempts, or Micro-Learn activity for third-party personalized advertising.
Future changes
If advertising features are introduced, this page and the Privacy Policy will be updated to explain the ad partners, data use, and available controls before or when the feature becomes active.
