Data Collection

What Data We DO NOT Collect

AstroCollect does NOT collect, transmit, or store any of the following:

• Personal information (name, email, phone number)
• Account credentials (no accounts exist)
• Usage analytics or statistics
• Crash reports
• Device identifiers (IDFA, UUID)
• IP addresses
• Location data (unless you explicitly enable it)
• Search queries
• Any data about your usage patterns

What Data the App Stores Locally

AstroCollect stores the following data exclusively on your device:

1. Photos you add
   • Celestial object photos you choose to upload
   • Stored in your device's Application Support folder
   • Never transmitted anywhere
2. Observation metadata
   • Object names
   • Capture dates (extracted from photo EXIF or current date)
   • Upload dates (when you added the photo)
   • GPS coordinates (only if you explicitly enable this feature)
3. App preferences
   • Language selection
   • GPS extraction preference (on/off)
   • Onboarding completion flag
   • Display preferences (sort order, filters)

Storage location: All data is stored locally in your device's Application Support directory (/Library/Application Support/AstroCatalog/) and UserDefaults. This data is:

• Sandboxed (only AstroCollect can access it)
• Backed up to iCloud/iTunes if you have device backups enabled (encrypted)
• Never sent to any server

Photo Metadata (EXIF)

What We Extract

When you add a photo, AstroCollect may extract the following EXIF metadata:

• Capture date: When the photo was taken (if available)
• Camera make/model: For future display features (not currently used)
• Camera settings: ISO, exposure, aperture, focal length (for future features)

What We DO NOT Extract by Default

• GPS coordinates: Location data is NOT extracted by default
  • You must explicitly enable "Save location data" in Settings
  • Even when enabled, GPS data never leaves your device
  • You can delete GPS data at any time by disabling the setting

Why We Extract Metadata

• To automatically determine when you captured each photo
• To provide better organization and sorting of your observations
• To display camera settings in future versions (optional feature)

Data Export/Import

Export Feature

You can export all your observation data (photos + metadata) to a ZIP file:

• Export is triggered manually by you
• Creates a local ZIP file on your device
• You can share this file via AirDrop, Files app, email, etc.
• We never see or access your export files

Import Feature

You can import previously exported data:

• Import is triggered manually by you
• Reads a ZIP file you select from your device
• Restores photos and metadata locally
• No data is sent anywhere during import

Privacy note: When you share your export file (e.g., via AirDrop to another device), you are responsible for ensuring the recipient is trustworthy. We recommend:

• Only share with your own devices
• Use secure transfer methods
• Disable GPS extraction before exporting if sharing with others

GPS/Location Data

Default Behavior

GPS coordinates are NOT extracted from photos by default.

Opt-In Feature

You can enable "Save location data" in Settings to extract GPS coordinates from photos:

• This is entirely optional
• Must be explicitly enabled by you
• Can be disabled at any time
• When enabled, GPS coordinates are:
  • Extracted from photo EXIF metadata
  • Stored locally on your device
  • Never transmitted anywhere
  • Never shared with any third party

Why We Offer This Feature

Some users want to remember where they captured their astronomical photos (e.g., dark sky sites, observatories). This feature is for them.

Privacy Warning

AstroCollect displays a warning when you enable GPS extraction:

"GPS coordinates reveal your location. Disable before sharing your data."

This reminds you to turn off GPS extraction before exporting data you plan to share.

Third-Party Services

AstroCollect does NOT use any third-party services, including:

• No analytics services (Google Analytics, Firebase, etc.)
• No crash reporting services (Crashlytics, Sentry, etc.)
• No advertising networks
• No social media SDKs
• No cloud storage services (except Apple's native iCloud for device backups)
• No backend servers

The app is entirely self-contained and offline-capable.

Data Sharing

General Policy

AstroCollect NEVER shares your data with third parties.

Your photos and observation metadata:

• Remain entirely under your control
• Are never sent to our servers (we don't have any)
• Are never shared with Olivier Teissonnière or any third party
• Are never sold
• Are never used for commercial purposes

Manual Sharing (Export)

You can voluntarily share your data by exporting a ZIP file. When you do:

• You decide who receives the data
• You choose the sharing method (AirDrop, email, etc.)
• We have no access to the file once created

Right to Opt-Out of Sharing/Selling

Since we never share or sell your data, there is no "sharing" or "sale" mechanism to opt out of. You already have complete control.

Data Retention

Retention Policy

All your data (photos and metadata) are retained:

• For as long as you want - as long as you keep the app installed
• You have full control: delete a photo, delete all data, whenever you want
• No automatic time limit (unless you choose to delete)

Complete Deletion

When you delete the app:

• All local data is deleted from the Application Support storage
• Preferences are deleted from UserDefaults
• No data persists after app deletion
• Exception: If you have iCloud backups enabled, data may be restored if you reinstall the app (controlled by Apple, not by us)

Future Improvements

We plan to add automatic iCloud synchronization. When this feature is added:

• It will be entirely optional (opt-in)
• You will have the choice to sync or not
• Data will be end-to-end encrypted
• This privacy policy will be updated accordingly
