Information We Collect

Flow Builder is designed with privacy in mind. We collect minimal information to provide you with the best possible experience:

  • Local Storage: Your yoga flows and preferences are stored locally on your devicein your browser (web app) or on-device storage (iOS and Android apps). We do not have access to this data.
  • iCloud Data (iOS): If you subscribe to a plan that includes iCloud Sync, your flows and settings are synced via Apple's iCloud service. This data is stored in your personal iCloud account and is governed by Apple's Privacy Policy. We do not have access to your iCloud data.
  • Cloud Sync (Android): On Android, you may optionally sync your data via Google Drive or Dropbox. When enabled, your flows and practice session data (including health metrics) are stored in your personal cloud account. We authenticate using OAuth 2.0 and only access app-specific storage. We do not access any other files in your cloud accounts.
  • Health Data (Android): With your explicit permission, the Android app integrates with Android Health Connect to read and write the following health data:
    • Heart Rate: We read heart rate data from Health Connect during yoga, meditation, and breathwork sessions to display real-time heart rate and calculate session analytics (average, minimum, and maximum heart rate). Heart rate samples are stored locally on your device as part of your practice session history.
    • Exercise Sessions: We write exercise session records (yoga, meditation, breathwork) to Health Connect so your practice appears alongside other fitness activities on your device.
    Health data is used solely to enhance your practice experience and provide session analytics. It is stored locally on your device and is only synced to cloud storage if you explicitly enable cloud sync. Health data is never sent to our servers, sold, or shared with third parties.
  • Posture Tracking (Android): With your permission, the Android app uses your device's accelerometer and gravity sensors to provide real-time posture feedback during practice. Posture metrics (posture score, duration, and correction count) are stored locally on your device as part of your session history. Sensor data is processed entirely on-device and is never transmitted to our servers.
  • Subscription & Purchase Data: If you subscribe to a paid plan through the iOS app or Android app, your purchase is processed entirely by Apple (App Store) or Google (Google Play). We do not collect or store your payment information. The platform may share a transaction receipt with us to verify your subscription status.
  • Camera & Microphone: Premium features such as Pose to Flow and Voice to Flow require camera or microphone access. This data is processed entirely on your device and is never uploaded to our servers.
  • Contact Information: When you contact us through our contact form or email, we collect your name and email address to respond to your inquiry.
  • Usage Analytics: We may collect anonymous usage statistics to improve our service, but this data cannot be linked back to you personally.
  • Facebook SDK (iOS): The iOS app includes the Meta (Facebook) SDK to support advertising attribution, install measurement, and app analytics. When you use the iOS app, the Facebook SDK may automatically collect and transmit the following information to Meta:
    • Device identifiers (such as the Identifier for Advertisers (IDFA), if you grant App Tracking Transparency permission, or an anonymized device identifier if you do not)
    • Device information (model, operating system version, language, time zone, country)
    • App events (such as app installs, app launches, in-app purchases, and subscription activity)
    • IP address (used by Meta for approximate location and fraud prevention)
    In compliance with Apple's App Tracking Transparency (ATT) framework, the iOS app will request your permission before enabling tracking. If you decline tracking, the IDFA is not shared and Meta receives only limited, non-personalized event data. Data collected by the Facebook SDK is governed by Meta's Privacy Policy and is used by Meta to measure ad performance, attribute installs, and provide aggregated analytics. We use this data solely to understand how users discover Flow Builder and to improve our marketing. You can opt out at any time by revoking the App Tracking Transparency permission in your device's Settings > Privacy & Security > Tracking.

Data Storage and Security

Your privacy and security are our top priorities:

  • iCloud Sync (iOS): When enabled, your data is synced through Apple's iCloud infrastructure using end-to-end encryption. We cannot read or access your synced data.
  • Cloud Sync (Android): When enabled, your data (including practice sessions and health metrics) is synced to your personal Google Drive or Dropbox account. Data is transmitted securely over HTTPS and stored within your own cloud storage account.
  • No Account Required: You don't need to create an account or provide personal information to use Flow Builder.
  • Secure Communications: All communications with our servers use industry-standard encryption (HTTPS).
  • No Data Sales: We never sell, rent, or share your personal information with third parties for marketing purposes.

  • Apple Music (MusicKit): If you connect Apple Music on iOS, we access your library metadata to sync music with your flows. We do not store or transmit your music data.
  • Meta (Facebook SDK) — iOS only: The iOS app integrates the Meta SDK for advertising attribution, install measurement, and aggregated analytics.
