We built Flintalk so the most sensitive part of your day, your live conversations, stays on your machine and out of sight.
Your documents, your knowledge bases, and your saved conversations live on your machine. Retrieval over them runs locally. We don't upload your files or your meeting content to train anything.
Call audio streams over an encrypted connection to the transcription service, is transcribed live, and is discarded. It is never written to disk, on your Mac or on any server. The only thing we keep is the minute count we need to meter usage.
The overlay is excluded from screen capture, so it stays invisible when you share your screen on Zoom, Google Meet, and Microsoft Teams. No bot joins the call, and no other participant sees it. We verified this against the real apps.
We store your sign-in session encrypted in the macOS Keychain, backed by Apple's Secure Enclave. It is never written in plain text.
The app is signed with an Apple Developer ID and notarized by Apple, so macOS Gatekeeper checks that it hasn't been tampered with before it runs.
We meter only the minutes you use, and we measure them server-side so the count stays accurate and a modified client can't fake it.
To answer a question, we send the detected question and any snippets you've chosen to use to the AI provider through our proxy, which keeps API keys server-side. Your full documents, your transcripts, and your audio are not uploaded. We don't store anything about your meeting beyond the minute count we use for billing.
