b. Lungy does not request or require any personal identifiable information such as name, email address, date of birth, or address for functionality.

c. Downloading, accessing, or otherwise using this App indicates that you have read this privacy policy and consent to its terms. If you do not consent to the terms of this privacy policy, please do not download, access, or otherwise use this App.

a. Lungy does not currently collect or require any personal identification information such as name, email address, date of birth, gender, and country to access and use the app. There is no login screen or registration to access the app.

b. You may be expected to provide your financial details (such as credit or debit card details) via your Apple ID, to the Apple App Store in order to become a paid subscriber or purchaser of this App. Additionally, Lungy may collect purchase data to aid with managing and handling user subscriptions, purchases, and promotions. This data may be collected but is not linked to your identity and only stored with anonymous App User IDs.

c. Lungy uses the microphone to recognize and respond to user breathing. No audio or microphone data is ever recorded, streamed, transmitted, or stored. The microphone data is analyzed and stored as encrypted numerical breathing data after each breathing exercise you complete. This data is entirely anonymized, the data remains on your device and is on-device encrypted.

d. Additionally, Lungy can use the camera (with TrueDepth on supported devices), with subsequent face-tracking, to help you position the phone for optimal breathing detection. The use of the camera positioning screen is entirely optional and at the user's discretion. No depth (including all TrueDepth data), video or camera data is ever recorded, streamed, transmitted or stored. No identifiable or recognizable face or face-tracking data is ever stored, and is only used for the purpose of tracking the positioning and orientation of the face. The positioning and any facial tracking data is not saved to the device at any time and these data only exist whilst i) a user's face is detected and ii) the camera positioning screen is visible to the user and will be immediately deleted and unrecoverable as soon as: i) a user's face is no longer detected and/or ii) the camera positioning screen is no longer visible or active. Similarly, TrueDepth data is never shared with any third parties, and does not leave the device. Additionally, it is not saved to the device at any time. If you would prefer to not use this face-tracking feature, please select 'Without Camera' during the tutorial, or set Face-Tracking to Off in 'Settings'.

e. Your privacy is a priority to us. For this reason, Lungy does not share any identifiable or user information with remote or cloud servers, it is not transferred, and stays on your device.

This tool allows us to collect anonymized data on app usage patterns, ensuring that no personally identifiable information is linked to the data collected.
