SolarScope creates no user account and sells no personal data.
The “Tonight’s sky” page asks for your permission before using your position. The coordinates are rounded before being sent to Nominatim to show an approximate town; the sky is then calculated on your device. They are neither stored by SolarScope nor linked to a profile. The same goes for the nearby meteorites search, where the position is rounded to about 10 km.
Some pages query science services from NASA, NOAA, ESA, The Space Devs and Where The ISS At. These providers may receive the usual technical information of a web request, including the IP address.
To know which missions are really used, SolarScope counts page views with Vercel Web Analytics. This service sets no cookie, builds no profile and does not follow visitors from one site to another. SolarScope only sends the page address, without parameters or passport code; Vercel also works out the country, device type and browser, in aggregate.
SolarScope creates no account. The browser may keep the selected audience or level, the light display mode, the passport progress and stargazing logbook, the step open in a lesson card and a temporary local cache of space weather. This information stays on the device and is not sent to SolarScope. The language is simply shown in the page address (/en for English).
The passport can be erased from the “Space passport” page. Other preferences and the cache can be removed in the browser’s storage settings; the weather cache also expires on its own. Questions sent to SolarBot go to Google’s Gemini service when Gemini is enabled, without being kept in a SolarScope database.
