Introduction
This Privacy Policy describes how Bart Migal ("we," "us," or "our") collects, uses, and protects your information when you use the Practice Butler mobile application ("App"). Practice Butler is designed to help musicians memorize music through personalized spaced repetition using video recordings.
We are committed to protecting your privacy and being transparent about our data practices. This policy explains what information we collect, how we use it, and your rights regarding your personal information.
Information We Collect
Information You Provide Directly
Video and Audio Recordings: When you use Practice Butler, you create video recordings of your musical practice sessions. These recordings are stored locally on your device and are not transmitted to our servers or any third-party services.
Optional Email Subscription: If you choose to subscribe to updates about the App through our website (practicebutler.com), we collect your email address. This is entirely optional and separate from using the App.
Information Collected Automatically
Device Permissions: The App requests the following permissions to function properly:
- Camera Access: To record video content for your practice sessions
- Microphone Access: To capture audio as part of your video recordings
- Photo Library Access: To allow you to save or manage your recorded videos within your device's photo library
- Speech Recognition: To enable optional voice commands and practice session summaries
App Store Analytics: We receive basic analytics data through Apple's App Store Connect, including general usage statistics, crash reports, and performance metrics. This data is anonymized and aggregated by Apple.
No Personal Identifiers: The App does not collect, store, or transmit any personal identifiers such as your name, email address, phone number, or device identifiers.
How We Use Your Information
Local Data Processing
Video Storage: All video recordings you create are stored locally on your device. We do not have access to, store, or process these recordings on our servers.
Practice Analytics: The App may analyze your locally stored videos to provide personalized spaced repetition scheduling. This analysis occurs entirely on your device.
Optional Features
Speech Recognition: When enabled, the App uses Apple's built-in speech recognition to process voice commands. This processing may involve sending audio data to Apple's servers in accordance with Apple's privacy policy.
Practice Session Summaries: When enabled, the App may use third-party artificial intelligence services (such as OpenAI's ChatGPT or similar services) to generate summaries of your practice sessions. When you use this feature:
- Audio or text data from your practice sessions may be transmitted to the third-party AI service
- This data is processed according to the third-party service's privacy policy
- You can enable or disable this feature at any time in the App settings
- We do not store or retain copies of data sent to these services
Email Communications: If you subscribe to our email list through our website, we use your email address to send you updates about the App, new features, and related information. You can unsubscribe at any time.
Data Sharing and Third-Party Services
No Data Sharing
We do not sell, trade, or rent your personal information to third parties. Since your video recordings are stored locally on your device, we do not have access to this content.
Third-Party Services
Apple Services: The App uses Apple's built-in speech recognition service when this feature is enabled. Apple's privacy policy governs how Apple handles this data.
AI Services: When you enable practice session summary features, your data may be processed by third-party AI services. These services have their own privacy policies that govern how they handle your information.
App Store: Your use of the App is subject to Apple's App Store privacy practices, including payment processing and app distribution.
Data Security
Local Storage Security
Your video recordings are stored locally on your device using standard iOS security measures. The security of this data depends on your device's security settings, including screen locks, device encryption, and other iOS security features.
Transmission Security
When optional features transmit data to third-party services (such as for AI processing), we use industry-standard encryption protocols to protect data in transit.
No Cloud Storage
We do not store any of your personal content or recordings on our servers or in cloud storage services.
Data Retention and Deletion

Your video recordings and all associated data are stored locally on your device. This data remains on your device until you:
- Delete individual recordings through the App

Children's Privacy
Practice Butler is appropriate for users of all ages. However, we do not knowingly collect personal information from children under 13. Since the App operates without user accounts and stores all data locally, no personal information is transmitted to our servers.
If you are a parent or guardian and believe your child has provided personal information to us, please contact us so we can address the situation appropriately.
International Data Transfers
The App is currently available only in the United States and Canada. When you use optional features that involve third-party AI services, your data may be processed by servers located in various countries. These transfers are governed by the privacy policies of the respective third-party services.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will notify you of any material changes by:
- Posting the updated policy on our website
- Providing notice through the App when feasible
- Sending email notifications to subscribers (if applicable)
Your continued use of the App after changes to this policy constitutes acceptance of the revised policy.
California Privacy Rights
If you are a California resident, you may have additional rights under the California Consumer Privacy Act (CCPA). Since we do not collect or store personal information beyond what is described in this policy, most CCPA rights do not apply to our data practices. However, you may contact us with questions about your privacy rights.
