PERIGEE is a real-time 3D map of everything near Earth. It is built to be private by default. This policy describes exactly what it does and does not do with your data — in plain terms, with no legalese padding.
PERIGEE has no accounts, no analytics, no ads, no tracking, and no third-party SDKs. There is no login, no advertising identifier, no cross-app tracking, and no behavioral profiling. Nothing you do in the app is measured or reported to us or to anyone else.
If you set an observer location — by searching a place, entering coordinates, or using your device's location — it is used only to compute which satellites and passes are overhead. That math happens locally on your device. Your location stays in your browser's local storage and is never sent to any feed provider.
The single exception is push alerts. If you enable them, your chosen coordinates and the label you picked for that location are stored on the operator's server together with your push subscription, so the server can decide when a pass, asteroid approach, fireball, or launch is relevant to you. That data is kept until you disable alerts. Your location is never sold, rented, or shared with anyone.
Push alerts are entirely opt-in. When you enable them, your browser's push subscription (an endpoint URL supplied by your browser's push service) plus your alert preferences and observer location live on the operator's server. When you disable alerts, that subscription and its stored data are deleted. Subscriptions that a push service reports as expired are also removed automatically.
PERIGEE draws its data from public space feeds. Your server makes standard requests to these sources; your coordinates are sent to none of them:
The only user-supplied text that ever leaves your device is the place name you type into the search box, which is sent to Nominatim to resolve into coordinates. Your resolved observer position is not.
PERIGEE is suitable for all ages and shows factual astronomical and orbital data only. It collects no personal information unless you enable push alerts — in that case your chosen coordinates, location label, timezone, and push endpoint are stored as described above, and deleted when you disable alerts.
