SparkFlow is built around a simple promise: your voice stays on your machine. This policy explains what the app does — and does not — send anywhere. We publish it in the belief that privacy claims should be verifiable, not just asserted.
Speech recognition runs entirely on your device using models you download (Whisper-family and Parakeet models). Your microphone audio is processed locally and is never uploaded to us or to any third party. The app works with your network disconnected — that is the simplest way to verify it yourself. Recordings are deleted after transcription (you can configure retention to your preference, including "delete immediately").
The app makes exactly three kinds of network requests, all optional or minimal:
No audio recordings. No telemetry or usage analytics. No advertising identifiers. This website sets no cookies and runs no tracking scripts.
Payments are processed by Stripe, whose privacy policy applies to payment data. We receive your email address and subscription status, which we use solely to deliver and renew your license key. License delivery emails are sent through Resend. We do not sell or share your information.
We retain the minimum records needed to operate licensing: your email and subscription state. Email us and we will tell you what we hold, correct it, or delete your account records. Deleting your records ends subscription-based license renewals.
Material changes will be announced on this page and by email where reasonable.
