Privacy

Vlucht in beeld is a hobby project by Processware (Emmeloord) and runs on its own hardware in the Netherlands. There are no accounts, no tracking cookies and no adverts. This is what is stored.

Visitor statistics

Per page view: the path, the referring site, the kind of device (phone/desktop) and how long the page was open. The visitor is identified by a hash that changes daily, without a cookie and without the IP address being stored. Retention period 90 days.

Places

A chosen place appears as coordinates (rounded to about 100 metres) in the address bar. If you save a place, we store the name you give it, those coordinates and a hash of your IP address (only to limit the number of new places per day; the address itself is not stored). The logbook of aircraft at that place is public to anyone who knows the link. A place that hasn't been viewed for 90 days is deleted, logbook and all; you can delete it yourself from the browser in which you created it, or on request by email.

Notifications

If you turn on notifications, we store the push address your browser creates (a long, random URL at Google, Apple or Mozilla), the place and the rules you chose. We can only use that to send notifications; it says nothing about who you are. You can turn them off in the 🔔 panel or in your browser settings; an address that no longer works is deleted automatically.

Your phone's location

"My location" asks your browser once for your position and puts it, rounded, in the address bar. The position is not stored separately.

Reports of aircraft that aren't on the map

If you report an aircraft with the 👀 button, we store what you filled in (type, seen or heard, number, time, direction, altitude) and the place, rounded to about one kilometre. The report is public: for an hour on the map and for 30 days on the reports page. To prevent one person filling the map, we also store the daily changing visitor hash (see above); no IP address. Reports are deleted after one year.

Sources and third parties

Aircraft data comes from adsb.fi, adsbdb and Planespotters.net; maps from Esri, PDOK, 3D BAG and OpenStreetMap; weather from Buienradar; orbital elements from CelesTrak. Your browser fetches map images and photos directly from those parties, who see your IP address when it does; beyond that we share nothing with third parties.

The flown track of an aircraft you click is fetched by our server from OpenSky Network. Your browser doesn't connect to OpenSky itself, so OpenSky doesn't see you; the server only asks about the aircraft.

On the ISS page there is a button for the NASA livestream. That video comes from YouTube (Google) and is only loaded when you click it yourself — until then nothing is loaded from Google. If you do click, Google sees your IP address and, once the video plays, may store data on your device, just as on YouTube itself. We use the youtube-nocookie.com address for this, which stores less than regular YouTube.

This site sets only one cookie, and only when you choose a language with the EN/NL button: taal (value nl or en), which remembers your language preference for one year. It contains nothing else and is not used for tracking. Apart from that, what your browser remembers are your own settings: your chosen place, your map layer and your 3D preferences. That stays on your device and goes nowhere.
