Deer Rock Studios ("we") describes how Vieira handles information.
Local processing
Your scripts and generated audio stay on your device. Vieira does not upload scripts to Deer Rock servers.
How speech is generated
Vieira uses Microsoft Edge's neural TTS engine via the local edge-tts Python package. Speech synthesis runs through that local toolchain. We do not operate a separate cloud TTS API for the app.
No accounts or telemetry
No analytics, no ads, no user accounts. Generation history (last items) is stored locally on your PC.
