Your voice stays yours.

Cadensa uses the microphone only when you choose to record speaking practice. Pronunciation analysis and supported speech recognition run on your device. Cadensa does not send practice recordings, recognized practice transcripts, or features extracted from your voice to our servers or to an AI provider.

Your practice history, scores, completed activities, saved phrases, preferences, and any recordings you keep are stored on your device. How long recordings are kept follows the controls you choose in the app. You can export your learning history and delete local history and recordings in Settings. An export is saved only where you choose to save it, and you control any copies you share.

No Cadensa account is needed for local practice or for an App Store subscription. Cloud history sync, online AI conversations, and improvement sharing are not available in the current version. Buying Cadensa Pro does not turn them on or include unlimited online AI use.

The app may contact our HTTPS service at api.annotateaudio.com to check which features are available, and to carry out account, export, or deletion requests for an account that already exists. That service runs on Alibaba Cloud infrastructure. As with any internet request, network providers process connection information such as your IP address and the time of the request in order to deliver and secure it. We do not use practice audio or learning content to train models.

If you have an existing account linked to your Apple Account, its credentials are kept in your device’s Keychain. Signing out, deleting cloud data, and deleting local copies are separate actions. A privacy request that is still pending may keep the identifiers needed to retry it when you reconnect; it does not keep conversation text. Contact us if you cannot complete a request in the app. If connected features change, the app will explain the change and give you separate controls for it.

Apple processes subscription payments through your Apple Account. To provide Pro access, Cadensa reads and verifies Apple signed transaction and subscription information on your device, including the product you bought, when it expires, and whether it renews or was revoked. We never receive or store your payment card details, and the app does not send purchase transactions to our servers.

Purchases can be restored on any device signed in to the same Apple Account: open Settings, choose Cadensa Pro, then tap Restore purchases. Subscriptions renew automatically unless canceled in your Apple subscription settings. Deleting the app, your local history, or a Cadensa account does not cancel an Apple subscription. See Apple’s instructions for canceling and our subscription help.

Cadensa is ad free. We do not sell your personal data, share it with advertising networks, or use third party advertising trackers in the app. Apple processes App Store and purchase information under Apple’s privacy policy.

You can change microphone and speech recognition permissions at any time in the iOS Settings app. Inside Cadensa, Settings has controls for:

• your local practice history and recordings
• exporting your learning history
• account copies kept after signing out, and older recovery copies
• an existing account’s cloud data, which has its own separate controls

Restoring a purchase never requires a Cadensa account.

Cadensa is rated 4+ and does not knowingly collect personal information from children. Practice data stays on the device, and no account is needed to use the app.

For access, correction, deletion, or any other privacy question, email [email protected]. Describe your request, but please do not send recordings, passwords, payment details, or Apple verification codes. Before we act on account data we may need enough information to confirm the account is yours.

We will update this page, and the date above, if the way the app handles data changes. Use of the app is covered by Apple’s Standard End User License Agreement. Cadensa is provided by Core Arc Studio LLC and was previously called Pique.
