Who runs Orrery Space

Orrery Space (orreryspace.com) is made and run by Harsh Unagar in India. Questions about privacy, and requests to see, correct or delete information, go to harshunagar@orreryspace.com.

What stays on your device

Orrery Space keeps a few settings in your browser's local storage, on your own device: your quiz stars, badges and quests, the S2 race's best score, the guide's level and language, units, sound on or off, the voice for the tour, the quality setting, the galaxy log, and a birthday if you type one into the time machine. None of it is sent anywhere. The 3D app also keeps a copy of itself so it opens offline. Clearing this site's data in your browser removes all of it.

Google Analytics

Orrery Space uses Google Analytics 4 to count visits: which pages are read, which worlds are picked and which views of the app are opened (for example the Moon explorer or galaxy mode), searches in the galaxy map, links followed out, the main button on a world's, system's or landing site's page, the level and language chosen in the guide, printing the lessons, and error messages, so that bugs can be found. Google records the browser, device type, screen size and an approximate location (country and city, worked out from the IP address, which Google Analytics 4 does not store).

• Outside the European Economic Area, the UK and Switzerland it sets the cookies _ga and _ga_LRPDS06DFS, which last up to two years.
• Inside them, and on the pages written for children (the guide and the lessons) wherever you are, it stores nothing on your device: Google receives a count of the visit without a cookie or an identifier.
• Analytics data is never used for advertising: ads personalisation and ad user data are switched off for every visitor.
• To opt out everywhere, use Google's Analytics opt-out add-on, or block cookies for this site.

Advertising

Google AdSense shows ads on the home page, the Lunar Mission Browser and the reference pages (worlds, planetary systems, galaxies). It shows none in the 3D app, the guide or the lessons.

• Every ad is non-personalised: chosen from the page it is on and your approximate location, never from your browsing history or a profile.
• Google may still use cookies or similar storage for these ads, to limit how often you see one, to stop fraud and abuse, and to count results.
• Google explains this in How Google uses information from sites that use its services and How Google uses cookies in advertising.

Children

Orrery Space is for everyone, children included. There is no sign-up, chat, comment box or upload anywhere on it. On the pages written for children there are no ads and no analytics cookies, and nowhere on the site are ads personalised. Orrery Space asks no one for personal information, and does not knowingly collect it from children. If you are a parent or teacher and think a child's information has reached us, for example in an email, write to harshunagar@orreryspace.com and it will be deleted.

Other services

• Hosting. Orrery Space is served by Hostinger. Like any web server, theirs keep standard access logs (IP address, time, page, browser) for security, under Hostinger's privacy policy.
• NASA. "Today's Earth" in the 3D app fetches that day's picture from NASA's GIBS service only when you ask for it; NASA's server sees your IP address as any website would.
• Read aloud. The tour's voice is your browser's own speech. Some browsers use an online voice, which sends the sentence being read to the browser maker's speech service.

Your rights

Under India's Digital Personal Data Protection Act 2023, the GDPR in Europe and the UK, and the privacy laws of US states, you can ask what information about you is held, and have it corrected or deleted. Orrery Space itself holds none beyond any email you send, which is kept only to answer it. For what Google holds, use the links above or My Ad Center. Write to harshunagar@orreryspace.com; you will get an answer within 30 days.

Changes

If this policy changes, the new version will be posted on this page with its date.
