Duet for Duo

Privacy policy

Effective November 9, 2026.

Practice on your device

Duet stores lesson progress, practice dates, saved note phrases and practice videos in its library on your iPhone. You do not need an account. Duet does not upload your practice videos, analyze your hands or identify notes in your videos.

Camera and microphone access are requested only when you choose to record practice. You can import a video through the system file picker instead. You can export or delete recordings and phrases from the Library. Deleting Duet removes its local library. Device backups are controlled by your Apple settings.

Earlier TestFlight links

Version 1.0 does not publish new public phrase links. If you created links in an earlier TestFlight build, About Duet provides a control to remove them on the installation that created them. The earlier service stored the phrase title, note events, sharing time, a hashed installation credential and publishing counters on Google Cloud. The credential authenticates link removal. Removing a link clears its phrase content and disables access. Copies already saved by recipients cannot be removed by Duet. Uninstalling the app alone does not disable earlier links. For help removing a link, contact us with its URL.

Exports, website visits and support

When you export through another app, the recipient and service you choose handle those copies under their own practices. If you contact support, we use the information you include to respond. Please do not send passwords or private recordings unless you intend to share them with support.

Google Cloud hosts these pages and the earlier link-removal service. It processes technical request information, including request times and network information, for delivery, security and troubleshooting. There are no advertising or third-party analytics SDKs in Duet. We do not sell your personal information or use it for advertising tracking.

Your choices

You can delete local phrases and recordings in the Library, revoke camera and microphone permissions in iPhone Settings, and contact us about earlier shared content or support correspondence. We retain earlier link records as needed to operate and disable those links, and support correspondence as needed to address your request and meet legal obligations.
