Answer
raus analyses your notes locally using rule-based profiles. There is currently no dedicated back end, user account or synchronisation. However, Android voice input or other operating system features may have their own processing paths, depending on the device settings and services you have chosen.
So not all speech processing is guaranteed to happen entirely offline. The analysis in raus runs locally, but your device’s voice input may use an external service depending on its settings. If you record particularly sensitive content, it’s best to check your input method and system settings.
