Local Dictation Privacy and Offline Operation
The default speech engine runs on your computer. This technical explanation distinguishes local recognition from updates and optional online services.
Local speech is the default
FU Flow ships Whisper models and runs recognition through whisper.cpp on the same PC. No FU Flow account or paid API key is required for that mode. Once installed, local dictation can work without an internet connection.
An optional remote provider changes the data flow
Settings also offers an OpenAI-compatible speech provider. When you choose it, the app sends recorded audio to the endpoint you configured. The provider may require credentials and charge for processing. Its privacy and retention terms apply. Keep the local provider selected if you want speech recognition to stay on your PC.
Update checks use the network
The app checks for a newer release after startup. Checking does not download an installer. If you choose an update, the app downloads it. These requests are distinct from speech transcription. The site and download host receive normal request metadata when your computer connects to them.
History and the destination app
Transcripts, dictionary rules and statistics are stored locally in the app database. Text is inserted through the Windows clipboard and paste workflow. Anyone with access to your local files or clipboard may be able to read it. The program receiving the text can store or sync it under its own settings.
Practical checks
- Confirm the local provider in Settings before dictating sensitive material.
- Use a short offline test to check the setup on your own PC.
- Review what is saved in History and what you copy into another service.
- If you report a bug, review the diagnostic text before sharing it.
