Version 1, September 2026. This policy covers the FlightPortrait network: the map and API at flightportrait.com/network, and the stations that feed it. It is operated by YODE PTE LTD, Singapore. The FlightPortrait frame, app and shop are covered by a separate policy.

What we collect when you feed

• The aircraft messages your receiver sends. These are public radio broadcasts, not personal data.
• Your station key, stored as a one-way hash. We do not store the key itself.
• Your station's approximate location, calculated from the aircraft it hears and rounded to about 11 km.
• Connection statistics: when the station was first and last seen, whether it is online, and its message rate.
• Your antenna position, if you use MLAT. It is held in memory only while your station is connected.

We do not store your IP address. It is used to keep the connection open and discarded when the connection closes. We do not ask for your name, email, or address. There are no accounts.

What we collect when you visit the map

• Your IP address and browser type, kept briefly for security and rate limiting.

We do not use analytics or advertising trackers. Aircraft photos are loaded from planespotters.net and map tiles from OpenFreemap directly by your browser, under their own privacy policies.

How we use it

• To combine your data with other stations' and show it on the map and in the API.
• To calculate aircraft positions with MLAT.
• To show your station on the coverage roster.
• To keep the service running and secure.

What is public

• Your station's generated identifier, approximate location, first and last seen dates, and online status.
• The combined aircraft data from all stations, published as open data under the ODbL 1.0 licence.

Your exact antenna position is never made public.

The Station setup page

If you use our Station software, its setup page runs in your browser on your own network. It requests map tiles from OpenFreemap, address search from Nominatim, ground elevation from Open-Meteo, and a rough starting position from ipwho.is. None of this data is sent to us.

A Station flashed from our SD card image, until it is set up, tells us its address on your home network (like 192.168.1.23) and its name, once a minute, so that the join page, opened on a phone on the same Wi-Fi, can link to its setup page. We match the two by your home's public IP address. This is held in memory for ten minutes, under a scrambled form of that IP address, and never written down; it stops once the Station is set up.

The Am I feeding page compares your public IP address with the stations connected right now. It happens in memory, under a scrambled form of the address, and nothing is written down.

Deleting your data

Email [email protected] with your station key and we will delete your station's history. Aircraft data already published under ODbL cannot be recalled.
