What Data We Collect

HealthWise collects the following information that you voluntarily provide: • Personal health data: age, sex, height, weight, health goals • Medical information: conditions, medications, blood test data (including photos sent for AI extraction) • Lifestyle data: smoking status, alcohol frequency, waist circumference • Meal photos and food logs • Water intake logs • Fasting sessions and history • Smoking logs (cigarette count per day, daily limits, quit date goals)

This data is stored locally on your device using Apple's SwiftData framework and is protected by iOS Data Protection encryption.

iCloud Sync If you are signed into iCloud and have iCloud Drive enabled, HealthWise automatically syncs your health data across your Apple devices via Apple's CloudKit service. Your data is stored in your personal iCloud account and subject to Apple's iCloud Privacy Policy. HealthWise does not have access to data stored in your iCloud account. You can disable iCloud sync for HealthWise at any time in iOS Settings → [your name] → iCloud → Apps Using iCloud.

Child Profiles & Parental Consent HealthWise allows parents and guardians to create child profiles. By creating a child profile, you confirm you are the parent or legal guardian and consent to the child's health data being stored locally, synced via iCloud, and — if AI features are enabled — processed by Google Gemini AI. Child profiles automatically disable features inappropriate for children. Parents can delete a child profile and all associated data at any time from Profile → Switch Profile → swipe to delete. Contact [email protected] with any questions about child data.

Device Permissions

HealthWise requests the following device permissions:

Camera: Used to photograph your meals so that Google Gemini AI can identify the foods and estimate their nutritional content. Meal photos are sent to Google's Gemini API and stored locally on your device.

Photo Library: Used to select meal photos for nutritional analysis, and blood test report photos for AI value extraction. Selected photos are sent to Google's Gemini API for processing and stored locally on your device.

Microphone: Used for voice food input on the Meal Entry and Food Advisor screens. Your voice is processed by Apple's Speech Recognition framework. Depending on your device and settings, audio may be sent to Apple's servers for recognition. HealthWise does not store or transmit your audio. You can disable microphone access at any time in iOS Settings.

Notifications: Used to send medication reminders at the times you specify. All notifications are generated locally on your device — no data is sent to any server to deliver them.

You can manage these permissions at any time in the iOS Settings app under HealthWise.
