Well, on the plus side, SoundCore (Anker) are at least reputable enough (even though security teams would still want to review that!):

Under the security part, they do seem to at least be compliant with your typical security standards (HIPAA, SOC 2 Type 1, etc.) and claim that all data is deleted within 12 hours of transcription. So it isn't like the contents of your meeting are being siphoned off to some fly-by-night service, at least.
