Your data. Your practice.
Updated November 1, 2026
Your practice, on your device
Guitar Rudiments is provided by Nicholas Gattuso. The app does not require an account and has no ads, subscriptions, or in-app purchases. Practice sessions, notes, exercise results, settings, and saved chord loops are stored locally on your device. We do not operate a server that syncs your practice records.
Microphone access
The tuner and optional accuracy mode use the microphone only after you choose to start them and grant permission. Audio samples are analyzed in memory on your device to estimate pitch, note onset, and timing. Guitar Rudiments does not save audio recordings or upload microphone audio. You can stop listening in the app or revoke microphone access in your device settings. Other practice tools work without microphone permission.
App updates and diagnostics
The app uses Expo's update service to check for and download compatible app updates. These requests include an installation identifier, the app's platform and runtime or update version, and may include information about a failed update or fatal error. Expo also receives ordinary network information, such as an IP address, when servicing a request. Installation identifiers and crash diagnostics support update delivery, reliability, and measurement of update usage. They are not used by us for advertising, tracking across other companies' apps, or building a personal profile. Microphone audio and your practice database are not part of update requests.
Links and support
Optional learning-source links open third-party websites, which have their own privacy practices. Our support and privacy pages are hosted by Netlify; the hosting provider processes ordinary request information needed to deliver and secure those pages. If you email support, we receive your email address and the information you choose to include. We use support correspondence to answer your request and maintain relevant support history. Please do not send audio recordings or sensitive information unless you want to share it for support.
Retention and your choices
Practice data remains on your device until you remove the app or remove its stored data. Operating-system backups and restores depend on your Apple device and iCloud settings; they are managed by Apple. We cannot retrieve or restore your local practice database. You can ask us about support correspondence or request its deletion through the support page. Expo and Netlify manage service logs according to their own privacy and retention policies. Apple may process App Store, TestFlight, or diagnostics information according to your Apple settings and Apple's policies.
