DuoAccent ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, share, and safeguard your personal information when you use our accent training platform, including our website at duoaccent.com and our mobile application (collectively, "the Service").
When you create an account, we collect your email address, name, password (managed securely through Firebase Auth -- we never store your password in plain text), native language, professional role, and target accent preference.
When you use our accent training features, we process your audio recordings through our AI scoring pipeline. Audio is sent to OpenAI Whisper API for transcription and analysis. Audio recordings are processed in real time and are not stored permanently. Anonymized, non-identifiable data derived from recordings may be retained to improve our scoring models.
We collect data about how you use the Service, including practice history, accent scores, drill completion rates, streaks, XP (experience points), achievements, leaderboard rankings, and progress metrics.
We collect device identifiers for the purpose of demo rate limiting (to prevent abuse of our free Instant Accent Demo feature). This may include a device ID or fingerprint.
When you install the app, we generate a randomized identifier and store it securely on your device. We use this identifier to detect when you switch between devices during practice. We do NOT use device hardware identifiers (IDFA, IDFV, Android Advertising ID).
When you complete a drill, our scoring system classifies your audio against multiple regional English accent profiles, including American and British. We collect both classifications regardless of which accent you've selected as your target, to improve our models. You can choose to display only your American score, only your British score, or both, in Settings → Accent Target.
When you subscribe to a paid plan, payment is processed by Dodo Payments, our third-party payment processor. We do not store your credit card number, bank account details, or other sensitive payment information on our servers. We receive only transaction confirmations and subscription status from Dodo Payments.

We do NOT sell your personal data to third parties.
We may also disclose your information if required by law, legal process, or governmental request, or to protect the rights, property, or safety of DuoAccent, our users, or others.
We retain your account data and usage data for as long as your account is active or as needed to provide the Service. Audio recordings are processed in real time and are not stored permanently.
If you delete your account, we will delete your personal data within 30 days, except where retention is required by law or for legitimate business purposes (such as fraud prevention or resolving disputes). Anonymized, aggregated data that cannot be used to identify you may be retained indefinitely.

If we become aware that we have collected personal data from a child under 13 without parental consent, we will take steps to delete that information promptly. If you believe a child under 13 has provided us with personal data, please contact us at privacy@duoaccent.com.
We take the security of your data seriously and implement appropriate technical and organizational measures to protect your personal information, including:
While we strive to protect your personal data, no method of transmission or storage is 100% secure. We cannot guarantee absolute security.
We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page and notify you via email or in-app notification where appropriate.
We encourage you to review this policy periodically to stay informed about how we protect your data. Your continued use of the Service after any changes constitutes your acceptance of the updated policy.
