Ashik Bhandari ("I", "me", or "my") built Attune as a free app. This page informs you of my policies regarding the collection, use, and disclosure of personal data when you use the app.
Information We Access
Apple HealthKit
Attune requests read-only access to the following Apple HealthKit data:
Step count
Active energy burned
Walking + running distance
Heart rate
This data is used solely to display your daily health metrics within the app. Attune does not write any data to HealthKit.
Account Information
When you create an account, Attune collects:
Email address (for login)
Name, date of birth, height, and weight (for personalized meal and exercise plans)
Fitness goals and dietary preferences
How Your Data Is Used
Meal & exercise plans: Your profile information (age, height, weight, fitness goal, and dietary preferences) is sent to our backend server and, from there, to our AI provider, Anthropic (the "Claude" API), solely to generate your personalized plan. Anthropic processes this data as our service provider and does not use it to train its models. This information is not sold or shared for any other purpose.
Quit challenges, journal entries, task lists, meditation progress, and tracking: This data is stored locally on your device. If you create an account and sign in, it is also synced to our backend server so your data is backed up and available across your devices. It is used only to provide the app's features and is never shared with or sold to any other parties.
Data Storage
Local data: Journal entries, tasks, quit challenges, daily tracking progress, meditation progress, and motivational preferences are stored on your device using standard app storage. They remain on your device even if you never create an account.
Server data: If you create an account and sign in, the following are stored on our backend server: account credentials (email and encrypted password), profile information, AI-generated plans, and a synced copy of your journal entries, tasks, meditation progress, and quit-challenge/tracking data. Health data from Apple HealthKit is never sent to the server.
Data We Do NOT Collect
Attune does not:
Use analytics, advertising, or tracking SDKs
Share or sell your data to third parties
Track your location
Access your contacts, photos, or other personal data
HealthKit Data
In compliance with Apple's HealthKit guidelines, health data accessed through HealthKit is:
Never shared with third parties
Never used for advertising or marketing purposes
Never sold to anyone
Never stored on external servers — HealthKit data remains on your device
Data Security
Passwords are encrypted using industry-standard hashing (bcrypt)
Authentication uses secure JWT tokens
API communications use encrypted connections
Data Deletion
You can permanently delete your account and all associated server data directly in the app: go to Profile → Delete Account. This removes your account, profile, AI-generated plans, and all synced data from our server. You can also request deletion by contacting me at the email below. Local data can be removed by signing out or by deleting the app from your device.
Changes to This Policy
I may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
