About the App in Development
Learning recordings and history are saved on your device, and pronunciation analysis is designed to run on the device too. There is no system for sending recordings to a server for analysis. You can delete your recordings or export files yourself.
The early free version is planned to be supported by Google AdMob banner ads. They will appear on Home and the lesson list, but not during lessons, reviews, or on the progress screen. You can still study when ads cannot be loaded.
To deliver ads, prevent fraud, and measure performance, Google’s advertising and consent SDKs handle data such as IP addresses, device identifiers, approximate location, ad impressions and interactions, and crash and performance information. No process is provided to pass recordings, transcripts, or lesson learning content to the advertising SDKs.
This version requests non-personalized ads and does not request tracking permission for access to the advertising ID. Google’s consent screen is shown where required, and you can change your choices through “Ad privacy settings” in the app’s Settings. For details, see Google’s Use of Data for Advertising and SDK Data Disclosures. The app is currently being prepared for release.
