Google says that the Location Permission used by Hybrid Assistant is not compliant with the Developer Program Policy.
Hybrid Assistant uses Location information to provide telemetry data for Hybrid Reporter charts and stats, and this is an integral part of the app purpose.
Location data is always stored locally to the device, and it's not shared with anyone unless the user explicitly exports the produced reports.
We're going to write to Google Support to sort this out and we're confident Hybrid Assistant will be available on the Play Store again soon...
Google is about to enforce Android 11 compliance for apps on the Play Store.
Last year we merged Hybrid Reporter into Hybrid Assistant to prepare for this compliancy requirement.
The update we just published fulfills the requirement that an app is not allowed to write to the filesystem at will.
This means that the _hybridassistant directory, where datafiles are stored, will be migrated to a private directory: this will be totally transparent to the average user, who will see a "Migrating" message on the first run only.
Reports will still be accessible from the Hybrid Reporter menu as always.
If you are an "advanced" user, willing to consult the Hybrid Assistant database directly, you'll find an "Export" button in the Hybrid Reporter Database Maintenance screen that will allow to copy the database on Goggle Drive, for example.
