Privacy Policy

This privacy policy explains how Goyodrive operates Sentence Monster and collects, uses, stores, and deletes personal information for the web and mobile services.

The service processes account information, learning progress, subscription and transaction identifiers, support requests, essential cookies, optional preference storage, Google Analytics when analytics consent is enabled, and Firebase Analytics events in the iOS app.

Users can request access, deletion, correction, restriction, portability, or objection through the privacy page, My Page, or email.

Information We Collect

Sentence Monster may collect account information, learning history, service usage logs, billing and subscription identifiers from payment processors or app stores, and privacy request records. After account deletion, a keyed pseudonymous account value and related API usage may be retained for up to 400 days solely to prevent free or paid usage resets, then deleted; the original email and learning content are not retained in that record.

Cookies and Analytics

Essential cookies keep login and security working. Optional storage and Google Analytics are used only after consent.

Processors

Sentence Monster uses LemonSqueezy for web payments, Apple App Store and Google Play for app store subscriptions, and Google for social login, email infrastructure, analytics when enabled, and Firebase Analytics in the iOS app.
