This section applies specifically to the VocabFolio Android mobile application. Mobile apps use a different technical stack from web browsers — traditional browser cookies are replaced by device-level identifiers and local storage mechanisms. This section explains what technologies the Android app uses in place of cookies.
When you use VocabFolio on Android, the following technologies serve similar functions to the cookies described in Sections 2–7 of this policy:
VocabFolio does not use any third-party advertising networks or ad SDKs in the Android app at launch. The Android Advertising ID (AAID) is collected solely for internal analytics. If we introduce advertising in the future, we will update this policy and notify you in advance.
The Android app is distributed via the Google Play Store and may use Google Play Services (e.g. for authentication via Google Sign-In). Google Play Services may collect usage data subject to Google's own privacy policies. We do not control or have access to data collected by Google Play Services beyond what is described in this policy.
