Privacy policy

Last updated 8 October 2026

Short version: The app collects nothing about you or your calls. The app runs on your Mac, and the only things that leave it go to the AI service you connect yourself.

Who we are

Murmury is a free Mac app made by an independent developer based in Italy. For anything about privacy, write to murmuryelf@gmail.com.

The app

• Audio. Murmury captures your Mac's system audio and your microphone and turns speech into text on your Mac. Audio is not recorded, not saved and never sent to us.
• Transcripts and answers live in memory while the app runs and are gone when you quit.
• What leaves your Mac. To write an answer, Murmury sends the text of what was said, your call description and your documents to the AI service you connected: Anthropic's API with your own key, or your own Claude Code login. That service processes it on your account, under its own terms and privacy policy. We never see it.
• First start. The speech model (about 1.6 GB) is downloaded once from Hugging Face.
• Your key and settings. An API key is stored in your Mac's Keychain. Settings stay on your Mac.
• Nothing else. No account with us, no analytics, no crash reports, no tracking.

This website

• The site and the download are hosted by Cloudflare (Pages and R2). Cloudflare processes technical data such as your IP address to deliver pages and files and to protect them from abuse.
• We count visits with Cloudflare Web Analytics. It uses no cookies and does not follow you across sites: it records anonymous page views, the page you came from, your country and your type of device.
• No cookies, no ads, no trackers. Fonts are served from this site, not from Google.

The waitlist

If you join the waitlist we store your email address, the date, the channel that brought you to the site (for example a link from Reddit or LinkedIn) and your country, in a Cloudflare D1 database. We use them only to email you when Murmury opens and about big updates, on the basis of your consent. We never sell or share them. To leave the list or have your data deleted, write to murmuryelf@gmail.com or use the unsubscribe link in any email.

The other people on your call

Murmury turns their voice into text on your Mac and sends the text of their questions to your AI service. Where the law requires it, telling them or getting their consent is up to you. See the Terms.

Your rights

Under the GDPR you can ask to access, correct or delete personal data and object to its use. The app sends us nothing, so we usually hold nothing about you beyond your waitlist entry or emails you sent us, which we delete on request. You can also complain to the Italian data protection authority, the Garante per la protezione dei dati personali.

Changes
