• QSO Logging: Your callsign and contact details are stored to maintain your amateur radio logbook
• Notifications: Alert you when satellites are approaching or passing overhead based on your notification preferences
• Grid Square Tracking: Calculate and display worked grid squares for VUCC award tracking
• Distance Calculations: Compute contact distances for DXCC and other award programs
• Calendar Integration: Add satellite pass events to your device calendar for planning
• SSTV Decoding: Process audio files to decode slow-scan television images transmitted by satellites and amateur radio operators

3.2 Data Export and Import

You can Manage your QSO log data in the following formats:

• CSV Format: Export
• JSON Format: Export / Import
• Image Format: Save to Gallery
• Email Export: Send your log data via email for backup purposes

These options are user-initiated and under your complete control.

4. Third-Party Services

4.1 N2YO Satellite Tracking API

Ham Satting uses the N2YO API to retrieve real-time satellite orbital data (Two-Line Element sets).

What information is shared:

• Your location coordinates (for calculating satellite visibility)
• Your N2YO API key (if you provide one)
• Satellite names you're tracking

4.2 Optional Amateur Radio Logging Services

What information is shared:

• Your amateur radio callsign
• QSO log data (date, time, frequency, mode, worked callsign, etc.)
• Your login credentials for these services (stored securely on your device)

5. Location Services

5.1 Why We Need Location Access

Ham Satting requires access to your device's location services to:

• Calculate accurate satellite pass predictions from your QTH
• Display real-time satellite positions relative to your location
• Show satellite footprints and visibility areas
• Calculate distances for DX contacts
• Determine appropriate elevation and azimuth angles

5.2 Location Data Usage

• Location data is used only while the app is active (foreground location access)
• Your location is converted to a Maidenhead grid square and stored locally
• Raw GPS coordinates are only sent to N2YO API for satellite calculations
• Location data is never stored on external servers
• You can manually set a default location if you prefer not to use GPS

5.3 Revoking Location Access

You can revoke location permissions at any time through your device settings:

• Android: Settings → Apps → Ham Satting → Permissions → Location
