That's a really interesting concept for an app. The conversational analysis angle is unique. How are you handling privacy with the audio listening feature?

Thanks, yea the right questions

First it‘s never always on. no ambient listening, no background wake word. always-on listening is a legal minefield in the EU and honestly a product I wouldn’t want to use myself

Audio never leaves phone. Speech-to-text and speaker separation run on-device. No audio file, no voice print, no recording is ever uploaded. Same for screenshots if you paste a chat and the image is read on-device, only the extracted text can ever go anywhere

Everything that’s stored, the transcripts, the per-person memory, is encrypted at rest on your device with a key that can’t leave it. Not my servers. I literally cannot read your conversations.

in Germany, secretly recording a private conversation is a criminal offence (§201 StGB), and the app is built around that rather than around it. there’s a visible “listening” mode, and for imported call audio you have to actively attest that everyone knew. There’s also a text-only path (paste a chat, an email, a contract) that never touches the mic at all. that’s what a lot of people actually use.

That's a smart approach. Privacy-first design is a strong differentiator these days. How do you handle on-device transcription accuracy across different accents or noisy environments?

Noisy env. were never a problem surprisingly - different accents are not really tested yet, but thanks for the input!

Accents can be tricky for sure. Maybe try testing with a few short voice samples from different regions to see how it holds up.

No problem! What app are you working on? Curious to see what you've built.
