Scribe (offline transcribing recorder) app records audio, stores it on device, reads files from device, if you ask it to. It doesn't have permission to access Internet, so it doesn't connect to any cloud service, let alone doesn't collect any data.
This format is interesting for privacy cautious institutions working with personal data, like healthcare, banks, retail and governmental services.
We believe, data should be in hands of the one who pays, he is the ultimate owner.
Yours sincerely,
