Privacy policy

Recordings

Recordings are made in your browser. To produce a transcript, the audio of an attempt is sent to our speech-to-text service (Cloudflare Workers AI) and discarded after transcription. We do not store your audio.

If your browser supports built-in speech recognition, it may be used as a fallback for live captions. That feature is provided by your browser vendor and subject to their privacy policy.

Transcripts and feedback

For AI feedback, your transcript and speaking metrics are sent to a language model running on Cloudflare Workers AI. We do not store transcripts or feedback on our servers.

Progress

Your session history, streak and settings are stored in your browser's local storage on this device. You can delete them at any time from the Progress page.

Usage limits and analytics

To enforce daily free limits we store a one-way hash of your IP address combined with the date. We record anonymous product events (for example, “practice started”) with a random device identifier to understand how the product is used. We do not use advertising trackers.
