The Mobile Geographics website does not track visitors or collect information, beyond logging IP addresses.
None of the Mobile Geographics apps (for macOS, iOS, and visionOS) track individuals. Anonymous analytics are collected via Telemetry Deck, to track usage and bugs. With the exception of the AIS programs below, no individual user information leaves your device.
If you sign up for AIS data sharing using SkunkTracker, your personal information might be logged by the AIS data sharing service you sign up for.
