Information we collect

Voice recordings

To process and carry out your command, a recording of your command and a transcript of your recording are created. Once the command is completed, we immediately delete the recording and transcription, unless you allow Mozilla to store them.

To help us improve Firefox Voice, you may choose to allow Mozilla to store your voice commands and transcripts of your commands. We store this data without personally identifiable information, which means we don’t know who said them.
