AccentMirror is developed and operated by Stuart Pendergast, based in the United Kingdom.
This policy explains what data AccentMirror collects, why, and what your rights are under UK GDPR and applicable data protection laws.
AccentMirror requires two things to work. Both are necessary for the app’s core features — neither is optional, and there’s no separate consent step for either beyond the one-time acknowledgement shown the first time you open the app.
Voice processing. When you record yourself speaking, that audio is sent to Microsoft Azure (Speech Services) for transcription and pronunciation scoring, and — for the initial “mirror” playback — to Deepgram for speech-to-text. The text of what you said is then sent to Anthropic (Claude AI) to generate your personalised coaching tips. Audio is processed in real time by each provider and is not retained by them after your request completes.
Progress and session backup. Your scores, practice phrases, and language settings are automatically backed up to secure cloud storage (Firebase) so your progress survives a reinstall or a new device. This starts the moment you first open the app, tied to an anonymous device identifier — no account or email is required for this to happen. If you later save your progress with an email address in Settings, that same backup becomes linked to your account instead of the anonymous identifier.
AccentMirror collects anonymised usage data (such as “session started” and “score shown”) to fix bugs and improve the app. No audio, transcriptions, or personally identifying information is ever included in this data. This is carried out under a legitimate interest basis rather than consent — we’ve assessed that it has minimal privacy impact while providing clear benefit in making the app work better for everyone. If you’d like to object to this processing, contact accentmirrorapp@gmail.com at any time.
Free-tier (Echo) users see ads to help cover the cost of the AI services that power every session. For users in the EEA, UK, and Switzerland, ad personalisation is managed through Google’s certified consent platform (Google UMP) — you’re asked to make a choice the first time you use the app, and you can change it at any time via Settings → Manage ad privacy within the app. If you consent to personalised ads, your device’s advertising identifier may be used. If you don’t consent, or you’re outside these regions, only non-personalised, contextual ads are shown, and no advertising identifier is used. We never sell your data to advertisers or anyone else.
Session history, scores, and coaching summaries are stored locally on your device, and are also automatically backed up to secure cloud storage (Firebase) so your progress survives a reinstall or a new device. This backup happens automatically from the moment you first open the app, tied to an anonymous device identifier — it does not require creating an account or entering an email address. If you later save your progress with an email address in Settings, that same backup becomes linked to your account. You can delete your on-device data by uninstalling the app; to remove your data from our servers entirely, use Delete Account in the app’s Settings, or contact accentmirrorapp@gmail.com.
No. AccentMirror works fully — including cloud backup of your progress — without ever creating an account or entering an email address. An anonymous identifier is generated automatically on first launch and is what your backed-up data is tied to. Creating an account with an email (via Settings → Save your progress) simply lets that same backup follow you if you sign in on a different device; it doesn’t change what’s collected or how it’s used.
