Privacy Policy

Last updated: 11/16/2025

Our Privacy Commitment

At Gilly, your privacy is paramount. We believe your health data belongs to you and only you. This privacy policy explains how we handle your information.

Data Storage

All your health data stays on your device. Gilly uses on-device storage (SwiftData) to store your injection logs, weight data, photos, and side effect records. We do not transmit this data to our servers or any third parties.

Apple Health Integration

If you choose to integrate with Apple Health (HealthKit), Gilly will:

  • Request permission to read weight and other health metrics you authorize
  • Optionally write injection records to HealthKit if you enable this feature
  • Only access data you explicitly grant permission for
  • Never share your HealthKit data with any third parties

All HealthKit data access is governed by Apple's strict privacy policies and your iOS permissions.

Progress Photos

Progress photos are stored locally on your device within the app's secure container. They are not uploaded to any cloud service unless you explicitly choose to back them up via iCloud (which is encrypted and controlled by you through your Apple ID).

Information We Collect

The only information we may collect includes:

  • Email address - Only if you join our waitlist or contact support
  • Crash reports - Anonymous diagnostic data to improve app stability (opt-in only)
  • Usage analytics - Anonymous, aggregated data about feature usage (opt-in only)

What We Don't Do

  • We don't sell your data
  • We don't share your data with advertisers
  • We don't track you across other apps or websites
  • We don't require an account to use the app
  • We don't store your health data on our servers

Third-Party Services

Gilly may use the following third-party services:

  • Apple App Store - For app distribution and in-app purchases
  • Apple HealthKit - For health data integration (your choice)
  • iCloud - For optional device backup (your choice via iOS settings)

Data Export and Deletion

You can export all your data at any time via the app's export feature (PDF reports, CSV files). You can delete your data at any time by deleting the app from your device. Since we don't store your data on our servers, deletion is immediate and permanent.

Children's Privacy

Gilly is not intended for use by children under 13 years of age. We do not knowingly collect information from children under 13.

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