Privacy & cookies

Last updated: 2026. This page explains what the poppo ADS-B service stores and which cookies it uses. It is a small, self-hosted hobby service run by the owner ("we").

What we collect

Account data: the name you choose and an access code. No email is required to use the map.
Technical data: your IP address and browser/device user-agent, recorded when you sign in and (for the owner's own statistics) when you view the map or pick aircraft.
Usage data: events such as "opened the map", "followed aircraft XYZ", "viewed area (approximate location)" — used only by the owner to see how the service is used.
