Information Used by the App

GrowZone uses limited data solely to provide core functionality:

  • Location information (optional):
    If you grant permission, your approximate location is used to determine your USDA growing zone, local weather, and planting recommendations. Location data is processed on your device and is not stored or shared by us.
  • Garden data:
    Plants, notes, photos, and journal entries you create are stored locally on your device and, if enabled, synchronized privately through Apple iCloud using your Apple ID. We do not have access to this data.
  • Photos:
    Photos you add to your garden or journal remain on your device or in your private iCloud storage. We do not upload or view your photos.

In-App Purchases

GrowZone offers a one-time in-app purchase to unlock premium features. Purchases are processed securely by Apple. We do not receive or store your payment information.


Third-Party Services

GrowZone uses Apple-provided services only, including:

  • iCloud for data synchronization (if enabled)
  • WeatherKit for weather information

These services are governed by Apple’s privacy policies.


Children’s Privacy

GrowZone is not directed to children under the age of 13. We do not knowingly collect personal information from children.


Data Security

We rely on Apple’s platform security features, including device encryption and iCloud security, to protect your data. While no system is perfectly secure, we take reasonable steps to ensure your information is handled responsibly.
