When you join the waitlist we store your email address and the time you joined, nothing else. It is used for one thing: telling you when SayFast is ready. Write to hello@sayfast.app and it is deleted.
Live words are recognised on your Mac. When you release the key, the recording of that dictation is sent to the transcription model to produce the final text, then discarded. If you turn on "keep audio", the last recordings stay on your Mac only, for retries.
Text cleanup and meeting notes send the transcribed text, not audio, to the model that writes them. Voices in meetings are stored on your Mac as numbers that describe the voice, never as audio.
Nothing you say or write is used to train models, by us or by the providers we use.
