Privacy Policy
Last updated: September 23, 2026
Nounce helps you hear, understand, and practice the pronunciation of English words you highlight while reading. This policy explains what data we handle and why. It covers the Nounce Chrome extension, Mac app, and web app, which follow the same practices.
What we collect and why
- The word or phrase you select. When you invoke Nounce on a highlighted selection, that text (and a short surrounding sentence, for contextual meaning) is sent to our backend to generate pronunciation and meaning. We do not scan, read, or transmit any page content you have not explicitly selected and acted on.
- Voice recordings you make. When you choose to practice a word, your microphone audio is captured and sent to our pronunciation-assessment provider to produce per-syllable feedback. Recording only happens when you start it.
- Your email address.Used to create and sign in to your account (passwordless one-time code), to manage your subscription, and to send you product emails such as a weekly word. Every one of those has a one-click unsubscribe. If you're in the EU, the UK or Switzerland, we send them only if you ask for them.
- Your first language and what you do, if you tell us. Both are optional. We use them only to choose and write the tips in your word emails, never for advertising. You can change or clear either one at any time on your profile.
- Your country. Taken from your connection when you use Nounce, and used only to decide which email rules apply to you. We do not store your IP address for this.
- A random device identifier. Generated locally for anonymous usage so we can apply the free daily quota fairly. It is not tied to your identity.
We do not collect browsing history, keystrokes, form data, or the contents of pages you visit.
How data is used
- To return pronunciation audio, IPA, contextual meaning, and practice feedback.
- To authenticate you and enforce free-tier daily limits.
- To process subscription payments (via Stripe).
We do notsell your data, share it with third parties for advertising, or use it for any purpose unrelated to delivering Nounce's core features. The marketing site counts visits using Cloudflare Web Analytics, which sets no cookies and builds no profile of you. Nothing you look up or say is ever sent to it.
Third-party processors
- Supabase — account authentication and data storage (US region).
- Anthropic (Claude) — generates contextual meaning and pronunciation tips.
- Microsoft Azure Speech — text-to-speech audio and pronunciation assessment.
- Cloudflare — hosts the backend API and caches audio.
- Stripe — payment processing; we never see your card details.
- Cloudflare Web Analytics — cookie-free, aggregate traffic measurement on the nounce.ai marketing site only. It sets no cookies and does not identify or follow you. Not loaded on app.nounce.ai, and not used in the extension or the Mac app.
Each processes data only to provide its part of the service.
Storage and retention
- Your saved words and account record are retained while your account is active.
- Cached pronunciation audio is stored to keep the service fast and inexpensive.
- Voice recordings are sent for real-time assessment and are not retained as a permanent library.
- Locally, the extension stores only your session token and device identifier. Signing out clears the session.
Your choices
- You can sign out at any time from the extension popup or web app.
- You can manage or cancel your subscription from the billing portal.
- You can change or clear your first language and profession on your profile page.
- You can pause or stop product emails from the link at the bottom of any of them.
