Privacy Policy

Last updated: April 21, 2026

Ankh ("we", "our", or "the app") is a personal fitness tracking application. We take your privacy seriously. This policy explains what data we collect, how we use it, and your rights.

1. Data We Collect

Health & fitness data (via Apple HealthKit): With your permission, Ankh reads the following data types from Apple Health: heart rate recovery, sleep analysis, active energy burned, step count, body mass, and body fat percentage. This data originates from your connected devices (e.g., Whoop, smart scales) and is read locally on your device.

Data you enter manually: Workout logs (exercises, sets, reps, notes), food entries (meals, calories, macros), supplement logs, body measurements, progress photos, and goals.

Photos: If you choose to add photos to share cards, those photos are processed entirely on your device. They are never uploaded to our servers.

Account information: If you choose to sign in with Apple for cloud sync, we receive your Apple ID identifier and, optionally, your name and email address. We do not receive your Apple ID password.

2. How We Use Your Data

All data processing happens on your device. Specifically:

• Your health data is read from Apple Health and displayed in the app's dashboard, charts, and share cards.
• Your manually entered data is stored locally on your device using Apple's SwiftData framework.
• If you enable AI analysis, your fitness data may be sent to Anthropic's Claude API for processing. This is only triggered when you explicitly tap "Analyze" and requires your own API key or an active Pro subscription.
• If you enable cloud sync, your data is encrypted and stored on Supabase servers in the EU (Frankfurt region). This is entirely optional.

3. Apple HealthKit Data

We comply with Apple's HealthKit guidelines:

• HealthKit data is never used for advertising or marketing purposes.
• HealthKit data is never sold to third parties, data brokers, or information resellers.
• HealthKit data is never shared with third parties for their marketing or advertising purposes.
• HealthKit data is only used for the app's primary purpose: displaying your fitness data to you.
• If cloud sync is enabled, HealthKit-derived data may be stored in your encrypted cloud backup for the sole purpose of restoring your data on another device.

4. Third-Party Services

Anthropic (Claude API): If you use AI analysis features, a summary of your fitness data is sent to Anthropic's servers for processing. Anthropic's privacy policy applies to that data. You can review it at anthropic.com/privacy.

Supabase: If you enable cloud sync, your data is stored on Supabase infrastructure in the EU. Supabase's privacy policy applies. See supabase.com/privacy.

Apple: Sign in with Apple is provided by Apple Inc. Apple's privacy policy applies to the authentication process.

We do not use any analytics SDKs, tracking pixels, crash reporting services, or advertising frameworks.

5. Data Storage & Security

Local data is stored on your device using Apple's SwiftData framework and iOS Keychain (for sensitive tokens). This data is protected by your device's encryption and passcode.

If you enable cloud sync, data is transmitted over HTTPS and stored in Supabase's EU servers. Authentication tokens are stored in the iOS Keychain, not in plain-text storage.

6. Data Retention & Deletion

Your data remains on your device until you delete the app. Deleting the app removes all locally stored data.

If you have cloud sync enabled, you can delete your cloud data by signing out from Settings. To request complete deletion of your cloud account and all associated data, contact us at the email below.

7. Children's Privacy

Ankh is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

8. Your Rights (GDPR)

If you are in the European Economic Area, you have the right to:

• Access your personal data
• Correct inaccurate data
• Request deletion of your data
• Export your data in a portable format
• Object to processing of your data

To exercise any of these rights, contact us at the email below.

9. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy in the app and updating the "Last updated" date above.
