The short version. Audio never leaves your device. Transcripts go to Anthropic's Claude API only when you trigger analysis, and aren't retained there. We don't sell your data. We don't train AI on it.

1. Who we are

Speakest is operated by Speakest Ltd, UK-registered. Email privacy@speakest.app for privacy questions. For UK GDPR purposes, we are the data controller.

2. Data we collect

Account information

Email, hashed password, optional display name. Stored in Supabase (EU-hosted).

Voice and speech data

Your voice is transcribed locally in your browser using the Web Speech API. Audio never leaves your device. Transcripts are sent to Anthropic's Claude API only when you trigger analysis or a journal summary, and aren't retained there for training.

Session metadata

Scores, word counts, duration, timestamps stored so your dashboard works.

Journal transcripts

If you opt to save a session as a journal entry, the transcript is stored server-side so daily summaries work across devices.

Payment information

Handled entirely by Stripe. We never see your card details.

3. How we use your data

We do not train AI on your data, sell to third parties, or use it for advertising.
