Usage Data (Stored Locally Only):
These records and app preferences are stored in the app's local data on your device. The developer does not receive them through the app. If you choose to send feedback by email, the support recipient receives the message and sender information through your email service.
For users in the European Economic Area (EEA), United Kingdom, and Switzerland, we process your personal information based on the following legal grounds:
The information we collect is used solely for the following purposes:
Local Storage: Practice history, Stability Value history, selected emotion labels, and preferences are stored locally in the app. The app does not provide cloud synchronization. Voice audio is held in a temporary app file during recording and is deleted when recording stops or the recording screen closes. If the app terminates unexpectedly, the app removes leftover recording files at its next launch. Only the selected emotion label and recording duration are retained.
Local app data may be included in device backups according to your iOS backup settings. The app does not add a separate encryption layer to its locally stored practice records. Protect access to your device and its backups using your device settings.
We commit to:
The app uses Apple services for optional in-app purchases, the operating-system microphone permission prompt, and the system email composer when you choose to send feedback.
App Store In-App Purchase: Used for processing subscription payments. All payment information is handled by Apple, and we do not have access to your payment details. Apple's Privacy Policy applies to payment processing.
Feedback Email: If you send feedback, the message is delivered to the support email address shown in the composer by the email service configured on your device. We do not send feedback unless you choose to submit it.
Analytics and Advertising: We do not use third-party analytics, advertising, or tracking services.
